Question

I have a problem with the following code:

#include <stdio.h>
#include <iostream>

int main () 
{
 int a, b;

 printf("Please type in your number a: ");
 scanf_s("%d", &a);

 printf("Please type in your number b: ");
 scanf_s("%d", &b);

 printf("Solution 1 (divide and modulus): %f\n", a / b +  a % b); 
 printf("Solution 2 (cast): %f", (float) a / b); 

 std::cin.get(); 
 std::cin.get(); 

 return 0;

}

I want my program to read two integers and i want to use two different methods to divide them without round-off errors. Sincerly the first solution does not work. The output are just zeros. I don’t know where the problem is.

Answer 1

The result of a/b + a%b is an integer (%d), but you are printing out a float (%f).
