How to stop C++ console application from exiting immediately?

I created an exe file in c. When I run it command prompt opens and then closes quickly and I cannot see the output. The program takes no runtime values from users. It reads data from a file. Is there any way to prevent this?

Run it natively from the command line.

Let's say that your file is in C:\awesomeness.exe

Open the cmd, type cd C:\ and then type awesomeness.exe

One classic way to do it:

#include <stdio.h>

int main() {
    puts("hai");
    getchar();
}

This will wait for keypress at the end.

Are you in Windows? If so, a quick and dirty way is to use the system() function in stdlib.h (make sure you include it) to execute the PAUSE command in the command prompt.

system("PAUSE");

If you are using Visual Studio, hit CTRL + F5 instead of F5 in order to run your program.

Using 'system("pause");' before ending main() is the most common method.

int main() {
    ...
    ...
    system("pause");
}
