Overload function: int and float

 
#include <iostream>
using namespace std;

int difference(int a, int b)
{
  return a-b;
}

float difference(float a, float b)
{
  return a-b;
}

int main()
{
  int (*p1)(int, int);
  float (*p2)(float, float);

  p1 = difference; // address of difference(int, int)
  p2 = difference; // address of difference(float, float);

  cout << p1(10, 5) << ' ';
  cout << p2(10.5, 8.9) << '\n';

  return 0;
}
