Thread: Linker Error

Hi all,

I have written a code for a program which detects whether a number is a factorial number or not. I am getting a linker error saying "undefined reference to WinMain@16" after compilation
of my program. Kindly help me to solve this problem. Thank you. Below is my code:

Code:

#include<stdio.h>
int main()
{   
    int i,n,prod=1;
    printf("Enter n to be checked");
    scanf("%d",&n);
    if(n==1 || n==2)
    {
            printf("n is a factorial number");
    }
    else if(n>2)
    {   
    for(i=1;i<=n/2;)
    {
     while (prod<=n)
           {
           prod*=i;
           i++;
           }
    }
    }
    if(prod==n)
                {
                printf("factorial");
                }
    else
                printf("not factorial");
    system("pause");
    return(0);
}

What compiler are you using, include the version information? What version of Windows are you using?
