  Home  C++ Operator Overloading

⟩ What is overloading template?

A template function overloads itself as needed. But we can explicitly overload it too. Overloading a function template means having different sets of function templates which differ in their parameter list. Consider following example:

#include <iostream>

template <class X> void func(X a)

{

// Function code;

cout <<”Inside f(X a) n”;

}

template <class X, class Y> void func(X a, Y b) //overloading function template func()

{

// Function code;

cout <<”Inside f(X a, Y b) n”;

}

int main()

{

func(10); // calls func(X a)

func(10, 20); // calls func(X a, Y b)

return 0;

}
