Function Overloading

In contrast, C++ supports function overloading which permits functions with the same name to support different parameter types and different return types.
This is often termed "a function with multiple type-signatures"

#include <iostream>

void outputWithNewline(int x)
{
    cout << "Integer value: " << x << endl;
}

void outputWithNewline(char *x)
{
    cout << "String value: " << x << endl;
}

The C++ compiler recognises that the multiple functions are strongly related, and calls the correct function (generates the correct instructions) depending on how the functions are called (i.e. with what parameter types).
