spliting numbers in c++

something

// Example program
#include <iostream>
#include <cmath>
using namespace std;

int main()
{
  // declaring variables:
  int a, remainder;
  int result, result2, result3;

  // process:
  a = 357;
  result = floor(a / 100);
  remainder = a % 100;
  result2 = floor(remainder / 10);
  remainder = a % 10;
  result3 = remainder % 10;
  // print out the result:
  cout << result;
  cout << result2;
  cout << result3;
  // terminate the program:
  return 0;
}
