Question

I am a beginner of C. I run the C program, but the window closes too fast before I can see anything. How can I pause the window?

For Linux; getchar() is all you need.

If you are on Windows, check out the following, it is exactly what you need!

kbit() function

• kbhit() function is used to determine if a key has been pressed or not.
• To use kbhit() in C or C++ prorams you have to include the header file "conio.h".

For example, see how it works in the following program;

//any_key.c

#include  
#include 

int main(){

    //code here
    printf ("Press any key to continue . . .\n");
    while (1) if (kbhit()) break; 
    //code here 
    return 0;

}

When I compile and run the program, this is what I see.

Only when user presses just one key from the keyboard, kbhit() returns 1.
