Division of integers

Cplusbug (1)
I want to convert an integer into two separate integers, thousands and hundreds

examples:

4796 = 4 and 796

12765 = 12 and 765



If I try using the following to get the thousands I get an error as the result is floating-point.


{
int thousands
int hundreds

thousands = 4796/1000
hundreds = 4796 - (thousands * 1000)
}



How can I get the result of the division as an integer?

Not that I can see.

#include <iostream>

using std::cout;

int main()
{
  int thousands;
  int hundreds;

  thousands = 4796/1000;
  hundreds = 4796 - (thousands * 1000);

  cout << "thousands: " << thousands << '\n' << "hundreds: " << hundreds;
}


No floating-point in there. Works as expected.

It's also possible to use std::to_string() and stoi(), but I think the above solution is better.

Curious as to why one might want to avoid %, as in

@Repeater's code largely, just another approach

  thousands = 4796/1000;
  hundreds = 4796 % 1000;

  cout << "thousands: " << thousands << '\n' << "hundreds: " << hundreds;
}

Modular arithmetic is not typically taught in US education until College or University, sadly. The idea of a remainder is something that was taught and forgotten sometime around fourth grade.

Hence, beginning programmers are not really aware of the concept, let alone useful application.

What are the actual code and error message(s) you are seeing?
