In C++, you can exit a program in these ways:
- Call the exit function.
- Call the abort function.
- Execute a return statement from
main.
exit function
The exit function, declared in <stdlib.h>, terminates a C++ program. The value supplied as an argument to exit is returned to the operating system as the program's return code or exit code. By convention, a return code of zero means that the program completed successfully. You can use the constants EXIT_FAILURE and EXIT_SUCCESS, also defined in <stdlib.h>, to indicate success or failure of your program.
Issuing a return statement from the main function is equivalent to calling the exit function with the return value as its argument.
Visual Studio 2013: Output window closes instantly. Posted by 5 years ago. Blocks as an IDE for basic projects. However, I'm transitioning to Visual Studio 2013. Every time I run a simple 'Hello World' program, the output is displayed for a split second before closing. Where can you find an advanced C software development. After program is compiled, click on Run button (next to compile). However, DevC has a problem. As soon as you Run the program, output window opens momentarily and then it closes. So to come around this solution, set a breakpoint at the end of main function and then click on Debug instead of running it.
abort function
The abort function, also declared in the standard include file <stdlib.h>, terminates a C++ program. The difference between exit and abort is that exit allows the C++ run-time termination processing to take place (global object destructors will be called), whereas abort terminates the program immediately. The abort function bypasses the normal destruction process for initialized global static objects. It also bypasses any special processing that was specified using the atexit function.
atexit function
Use the atexit function to specify actions that execute prior to program termination. No global static objects initialized prior to the call to atexit are destroyed prior to execution of the exit-processing function.
return statement in main
Issuing a return statement from main is functionally equivalent to calling the exit function. Consider the following example:
The exit and return statements in the preceding example are functionally identical. However, C++ requires that functions that have return types other than void return a value. The return statement allows you to return a value from main.
Destruction of static objects
When you call exit or execute a return statement from main, static objects are destroyed in the reverse order of their initialization (after the call to atexit if one exists). The following example shows how such initialization and cleanup works.

Example
In the following example, the static objects sd1 and sd2 are created and initialized before entry to main. After this program terminates using the return statement, first sd2 is destroyed and then sd1. The destructor for the ShowData class closes the files associated with these static objects.
Another way to write this code is to declare the ShowData objects with block scope, allowing them to be destroyed when they go out of scope:

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.
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:
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'.
Peace and freedom,
Colin Laplace
Getting Dev-C++
The author has released Dev-C++ as free software (under GPL) but also offers a CD for purchase which can contain all Bloodshed software (it's customizable), including Dev-C++ with all updates/patches.

You should let the installer put Dev-C++ in the default directory of C:Dev-Cpp, as it will make it easier to later install add-ons or upgrades.
Using Dev-C++
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.
- 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.
- 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:
- 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.
- 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.
- Go to the 'Execute' menu, choose 'Run'.

' menu, choose 'Parameters' and type in any paramaters you wish to pass.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:
- 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.
See the Dev-C++ help topic 'Debugging Your Program' for more information.

Dev C++ Closes After Runners
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.
