MOD calculation / reversing

[wilson bibe]

Maybe this function can help you:

#include <stdio.h>
#include <conio.h>

int main(void)
{
int a,b,res

printf ("\nenter a number:");
scanf ("%d", &a);

a = a * a;
a= int a;

printf ("\nenter a number:");
scanf ("%d", &b);

b = b;

res = a / b;

a = a * res;

a = int a;

res = a / b;

printf("\nResult of division of %d / %d = %d. \n",a,b,res));

getch();
return(0);
}
