Beginner needs help with closing programs please.

I am a beginner and i am typing in some simple program code and most of my programs are running but close immediately. I am using Dev-C++, Here is some code maybe someone can school me a bit???

Code:

#include <stdio.h>

int radius, area;

int main(void)
{
    printf( "Enter radius (i.e. 10): " );
    scanf( "%d", &radius );
    area = (int) (3.14159 * radius * radius);
    printf( "\n\nArea = %d\n", area );
getchar();
return 0;
}

 

Open a console window (cmd) and run the program.

If you are a beginner use Turbo C - it's a free download and easy to install and use - it was the number 1 compiler for Ms-Dos.

And, dont have any apprehensions about using Turbo C just because ms-dos is obsolete - you will find it's still the best way to learn C!
