What is Dev-C++?
Dev-C++, developed by Bloodshed Software, is a fully featured graphical IDE (Integrated Development Environment), which is able to create Windows or console-based C/C++ programs using the MinGW compiler system. MinGW (Minimalist GNU* for Windows) uses GCC (the GNU g++ compiler collection), which is essentially the same compiler system that is in Cygwin (the unix environment program for Windows) and most versions of Linux. There are, however, differences between Cygwin and MinGW; link to Differences between Cygwin and MinGW for more information.

Nov 10, 2016 DEV-C for Windows contains all standard features necessary for creating, fixing, and executing programs written in C program languages. As C is an object-oriented expansion of C, it also supports earlier versions of the language. Precision tune auto care md. We recommend reading this tutorial, in the sequence listed in the left menu. C is an object oriented language and some concepts may be new. Take breaks when. C (pronounced 'see-plus-plus') is an object oriented, general purpose programming language that was created in 1983 by Bjarne Stroustrup. It's used mainly for desktop software and game development, and is an extremely useful programming language to know. Bloodshed Dev-C is a full-featured Integrated Development Environment (IDE) for the C/C programming language. It uses Mingw port of GCC (GNU Compiler Collection) as it's compiler. Dev-C can also be used in combination with Cygwin or any other GCC based compiler. Feb 01, 2011 This video is an introduction to C programming using the BloodShed Dev C IDE and compiler. This tutorial is designed for people that are completely new to computer programming.
Bloodshed!?
I'll be the first to say that the name Bloodshed won't give you warm and fuzzies, but I think it's best if the creator of Bloodshed explains:
First I would like to say that I am not a satanist, that I hate violence/war and that I don't like heavy metal / hard-rock music. I am french, but I do know the meaning of the 'Bloodshed' word, and I use this name because I think it sounds well. If you are offended by the name, I am very sorry but it would be a big mess to change the name now.I'll be the first to say that the name Bloodshed won't give you warm and fuzzies, but I think it's best if the creator of Bloodshed explains:
There's also a reason why I keep the Bloodshed name. I don't want people to think Bloodshed is a company, because it isn't. I'm just doing this to help people.
Here is a good remark on the Bloodshed name I received from JohnS:
I assumed that this was a reference to the time and effort it requires of you to make these nice software programs, a la 'Blood, Sweat and Tears'.

Using Dev-C++
This section is probably why you are here.
This section is probably why you are here.
All programming done for CSCI-2025 will require separate compilation projects (i.e. class header file(s), class implementation file(s) and a main/application/client/driver file). This process is relatively easy as long as you know what Dev-C++ requires to do this. In this page you will be given instructions using the Project menu choice. In another handout you will be given instructions on how to manually compile, link and execute C++ files at the command prompt of a command window. See here.
Step 1: Configure Dev-C++.
We need to modify one of the default settings to allow you to use the debugger with your programs.
We need to modify one of the default settings to allow you to use the debugger with your programs.
- Go to the 'Tools' menu and select 'Compiler Options'.
- In the 'Settings' tab, click on 'Linker' in the left panel, and change 'Generate debugging information' to 'Yes':
- Click 'OK'.
Step 2: Create a new project.
A 'project' can be considered as a container that is used to store all the elements that are required to compile a program.
A 'project' can be considered as a container that is used to store all the elements that are required to compile a program.
- Go to the 'File' menu and select 'New', 'Project..'.
- Choose 'Empty Project' and make sure 'C++ project' is selected.
Here you will also give your project a name. You can give your project any valid filename, but keep in mind that the name of your project will also be the name of your final executable. - Once you have entered a name for your project, click 'OK'.
- Dev-C++ will now ask you where to save your project.
Step 3: Create/add source file(s).
You can add empty source files one of two ways:
You can add empty source files one of two ways:
- Go to the 'File' menu and select 'New Source File' (or just press CTRL+N) OR
- Go to the 'Project' menu and select 'New File'.
Note that Dev-C++ will not ask for a filename for any new source file until you attempt to:- Compile
- Save the project
- Save the source file
- Exit Dev-C++
- Go to the 'Project' menu and select 'Add to Project' OR
- Right-click on the project name in the left-hand panel and select 'Add to Project'.
EXAMPLE: Multiple source files In this example, more than 3 files are required to compile the program; The 'driver.cpp' file references 'Deque.h' (which requires 'Deque.cpp') and 'Deque.cpp' references 'Queue.h' (which requires 'Queue.cpp'). |
Step 4: Compile.
Once you have entered all of your source code, you are ready to compile.
Once you have entered all of your source code, you are ready to compile.
- Go to the 'Execute' menu and select 'Compile' (or just press CTRL+F9).It is likely that you will get some kind of compiler or linker error the first time you attempt to compile a project. Syntax errors will be displayed in the 'Compiler' tab at the bottom of the screen. You can double-click on any error to take you to the place in the source code where it occurred. The 'Linker' tab will flash if there are any linker errors. Linker errors are generally the result of syntax errors not allowing one of the files to compile.
Step 5: Execute.
You can now run your program.
You can now run your program.
- Go to the 'Execute' menu, choose 'Run'.
Disappearing windows
If you execute your program (with or without parameters), you may notice something peculiar; a console window will pop up, flash some text and disappear. The problem is that, if directly executed, console program windows close after the program exits. You can solve this problem one of two ways:
If you execute your program (with or without parameters), you may notice something peculiar; a console window will pop up, flash some text and disappear. The problem is that, if directly executed, console program windows close after the program exits. You can solve this problem one of two ways:
- Method 1 - Adding one library call:
On the line before the main's return enter:system('Pause');
- Method 2 - Scaffolding:
Add the following code before any return statement in main() or any exit() or abort() statement (in any function):/* Scaffolding code for testing purposes */
This will give you a chance to view any output before the program terminates and the window closes.
cin.ignore(256, 'n');
cout << 'Press ENTER to continue..'<< endl;
cin.get();
/* End Scaffolding */ - Method 3 - Command-prompt:
Alternatively, instead of using Dev-C++ to invoke your program, you can just open an MS-DOS Prompt, go to the directory where your program was compiled (i.e. where you saved the project) and enter the program name (along with any parameters). The command-prompt window will not close when the program terminates.
For what it's worth, I use the command-line method.
Step 6: Debug.
When things aren't happening the way you planned, a source-level debugger can be a great tool in determining what really is going on. Dev-C++'s basic debugger functions are controlled via the 'Debug' tab at the bottom of the screen; more advanced functions are available in the 'Debug' menu.

Using the debugger:
The various features of the debugger are pretty obvious. Click the 'Run to cursor' icon to run your program and pause at the current source code cursor location; Click 'Next Step' to step through the code; Click 'Add Watch' to monitor variables.
Setting breakpoints is as easy as clicking in the black space next to the line in the source code.

Dev-C++ User F.A.Q.
Why do I keep getting errors about 'cout', 'cin', and 'endl' being undeclared?
It has to do with namespaces. You need to add the following line after the includes of your implementation (.cpp) files:

How do I use the C++ string class?
Again, it probably has to do with namespaces. First of all, make sure you '#include <string>' (not string.h). Next, make sure you add 'using namespace std;' after your includes.

C++ (pronounced 'see-plus-plus') is an object oriented, general purpose programming language that was created in 1983 by Bjarne Stroustrup. It's used mainly for desktop software and game development, and is an extremely useful programming language to know.
So to start C++ programming, you'll need some way to write your C++ code, and then also a compiler which turns that code into something that your computer can directly read (often called 'machine language'). If you're using the Mac OS X operating system or a Linux distribution, I'd recommend using any text editor of your choice to write your code (I particularly like Sublime Text 2), and then using the 'g++' compiler to compile your code via the Terminal. For (Mac) OS X, g++ can be very easily installed as it comes bundled along with XCode.
Another popular choice for C++ coding and compilation is using an Integrated Development Environment (IDE) in which you can write and compile your code. For OS X you might want to use XCode if you're feeling worried about the g++ route (g++ can be a little complicated), and if you're using Windows, popular IDEs include Code::Blocks, which I personally recommend however does require some setup at the start (you may need to do some research), and Visual C++ Express, which is much easier to set up, however will require some sort of application pausing before the end of the 'main' function in most cases as it generates a window which will disappear after execution. If you decide to go with Visual C++ Express, just keep this in mind -- you may wish to put the
system('PAUSE');
or _getch();
lines before the end of your 'main' function (the latter of which requires you to #include <conio.h>
) -- if you don't understand what this means, you will soon enough.So by this point, you should have your development environment properly set up (even if you don't entirely know how to use it yet). If you're using an IDE, create a new C++ project, often called a 'console project', and remove any code/text which is generated for you, and if you're using a separate text editor and compiler, just create a new file with the '.cpp' extension (the file extension for C++ source files) - I'm going to name mine 'project.cpp'.
To start off with, we're just going to add what's called a 'comment' to the top of our file which says that we've written the program. Comments are simply notes that you write (to either yourself, your team, or whoever else might see the code) that the C++ compiler completely ignores, and so these don't affect how your application actually runs. We can do single-line comments in C++ by using a double slash (
//
) and multi-line comments using /*
to start the comment, and */
to end the comment. Take, for example, the following:After a comment on your top line (which isn't entirely necessary), we need to 'include' a few things before we begin writing our main application logic. When we 'include' things in C++, we're simply taking pieces of pre-written code from a file - as such, includes are usually done at the start of a section of code so that the functionality can be used in the rest of the code. In this case we want to include the 'iostream' file (which stands for input output stream) so we can output and take in basic text data. These includes always start with a hash symbol (
#
), and then use the include
keyword followed by the name of the file we wish to include (which we specify, in this case, in angle brackets):As alluded to earlier, the stuff inside 'iostream' is for inputting and outputting text. The two most well-known things in here are called
cout
and cin
(pronounced 'see-out' and 'see-in'), which are for outputting data and getting data from the user. These both, however, require the 'std' namespace - I'm not going to go into great detail about namespaces right now, but essentially just think about different namespaces as different drawers. A lot of the core C++ standard stuff is in the 'std' drawer and we can specify this by either writing std::
before every time we write cout
, cin
, and other things which require it, or for our simple purposes here, we can just use the namespace throughout out whole document. This is done by writing the using
keyword, followed by the namespace
keyword, followed by the namespace name, in this case, std
:Notice that I also finished the line by using a semicolon (
;
) - lines are often finished with a semicolon in C++ to show that the instruction or the line has finished. In this case, we're telling the compiler that we're done specifying the namespace by writing the semicolon.Dev C++ Lessons Youtube
With the top part of our document setup, we can actually begin writing our program's point of entry. https://potenttrends554.weebly.com/traktor-scratch-duo-2-upgrade-to-pro.html. All basic C++ programs start at what is called the 'main' function. A function is just a piece of code with a name, and that name, in this case, is 'main'. Functions also have a type, generally speaking the 'main' function should have the integer (whole number) type, and this is shown by writing the
int
keyword before the function name. This function type means that inside the function we must have a line which returns an integer value - don't worry too much about what this means right now, but if we return '0' from main, it generally means that we did everything without any errors. After we've written the function's name, we have to specify some brackets (which some people populate with some things, but we're going to leave them empty), and then some curly brackets which will actually contain our main application code. For now, I'm just going to put a comment in there. Our code so far should look as follows:Notice that I put a tab-space before the comment - this is because the comment is inside the 'main' function and I wanted to visually show this. Indented code isn't necessary for your code to compile and run correctly, however it makes finding errors a hell of a lot easier, and if you don't do it, nobody will like you (or want to work with you!).

While we're talking about the 'main' function itself, let's put in that 'return' line we talked about earlier so that our main function abides to its type. This is done by simply writing the
return
keyword followed by the value which you want to return, followed by a semicolon - so in this case, return 0;
. This will actually stop our 'main' function's execution though, so we want it to be the very last line of the function:From here, we're going to complete our basic program by simply getting it to output 'Hello World!' (or text of your choice) to the screen. As alluded to earlier, this is done by using
cout
(which, remember, is in the std
namespace). We can output a combination of different letters, numbers, and symbols, known as a string, by writing the cout
keyword, followed by insertion operators, <<
, followed by our string which is represented by wrapping in double quotes. We also need a semicolon to end the line.The way
cout
works, is essentially that you can just put insertion operators after each piece of data you want to output to output some more. Numbers don't have to be surrounded in double quotes to be processed in the correct way be the compiler, so if we wanted to output a number after our 'Hello World!' piece of text, we could either put it inside our string, which would encapsulate the data, or we could put it after another set of insertion operators (and move the semicolon to the 'new' end of the line):You should try to get used to this functionality. Without looking at the snippet below which reveals the answer, try to create a basic
cout
What does window auto tuning do. which would output a sentence with a number in the middle.We can add newlines to this output by either writing a backslash followed by the letter 'n' in a string (remember that strings are encapsulated by double quotes), or by using the
endl
keyword after some insertion operators. So our final piece of code which we're going to compile and run (which I've commented a bit to make it easier to understand), is as follows:To compile and run the code in an IDE, you can usually just hit a conveniently placed 'Run' or 'Debug' button (Key shortcuts of F8 in Code::Blocks, F5 in Visual C++ Express, and ⌘+R in XCode), however the process of compiling and running is slightly more confusing when you have a separate text editor and compiler. If this is the case, save the file with the code we've written (and with the '.cpp' file extension, so call it something like 'project.cpp'), and then open up a Terminal window (if you don't know how to do this in your OS, Google it). You can then navigate to wherever your project file (i.e. 'project.cpp') is stored using the 'cd' command (again, you'll have to Google if you don't know how to do this), and then run some compilation and running commands which are compiler and OS-specific. If you're using g++, you can run
g++ -o project project.cpp
to compile the code in 'project.cpp' to a file named 'project', and then on OS X and Linux you can run ./project
to run the generated 'project' file (and hence the program) itself.Dev C++ For Windows 10
In future tutorials I will expect you to know how to compile and run code in your own development environment, so it'd probably be a good idea for you to create a few C++ projects and compile/run them to get used to your development environment. As a little challenge to tie off the information in this tutorial (which will, of course, be built upon in future tutorials), try writing another
cout
line after the one we've already written that outputs something else.
