13. FUNCTION OVERLOAD: several functions can be declared with the same name provided there is a difference in their parameter list

One important advantage of C++ is the OPERATOR OVERLOAD. Different functions can have the same name provided something allows the compiler to distinguish between them: number of parameters, type of parameters...

using namespace std;
#include 

double test (double a, double b)
{
  return a + b;
}

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

int main ()
{
  double   m = 7,  n = 4;
  int      k = 5,  p = 3;

  cout << test(m, n) << " , " << test(k, p) << endl;

  return 0;
}

Output

11 , 2
