void fact(int num); 

int main(void)

{

   int num;

    cout<<"Enter the number to find factorial\n";

    cin>>num;

    fact(num);

    getch();

    return 0;

}

void fact(int num)

{

    int i,f=1;

    for(i=1; i<=num; i++)

    {

   f=f*i;

     }

cout<<"Factorial of "<<num<<"is:"<<f;

}
