C++ - arithmetic operators example

#include <iostream>
using namespace std;
 
int main (){
  float a = 25;
  float b = 10;

  cout<<"a = "<<a<<", b = "<<b<<"\n\n";

  //Add a and b
  float result_add = a + b;
  cout<<"a + b = "<<result_add<<"\n";

  //Subtract b from a
  float result_sub = a - b;
  cout<<"a - b = "<<result_sub<<"\n";

  //Multiply a and b
  float result_mul = a * b;
  cout<<"a * b = "<<result_mul<<"\n";

  //Divide a by b
  float result_div = a / b;
  cout<<"a / b = "<<result_div<<"\n";

  //return division remainder - works with integral operands,
  //for other types cmath's fmod function can be used
  int result_modulo = (int) a % (int) b;
  cout<<"a % b = "<<result_modulo<<"\n";  
  return 0;
