    @Pushkar: dont use getch(), getch() is not included in standard c++ library.
    Instead maintain structure like this.
    #include<iostream>
#include<cstdlib>
int  main(int argc,char* argv[])
 {
 //....codehere.....
 system("PAUSE");
 return 0;
 }

    #include<stdio.h>
    #include <stdlib.h>
    main()
    {
    float area;
    int radius=1;
    area=circle(radius);
    printf("%f",area);
    }
    circle(int r)
    {
    float a;
    a=3.14*r*r;
    system("PAUSE");
    return(a);

    }
    i wrote this program, the output window was appeared but when i pressed any key to continue, the output window get disappeared 😔

    Well Pushkar in my opinion you need to put system("PAUSE") just before the closing braces of main function .Try this code:

    #include<stdio.h>
#include <stdlib.h>
circle(int r);
main()
{
float area;
int radius=1;
area=circle(radius);
printf("%f\n",area);
system("PAUSE");
return 0;
}
circle(int r)
{
float a;
a=3.14*r*r;

return(a);

}
