What are some examples of function overloading in C++ templates?

Can you explain function overloading in C++ templates with examples?

Sure! Function overloading allows you to define multiple functions with the same name but different parameters. In C++ templates, this means you can create functions that work with different data types.

Can you give me a specific example of function overloading using templates?

Absolutely! Here's a simple example:

#include <iostream>
using namespace std;

template <typename T>
T add(T a, T b) {
    return a + b;
}

int add(int a, int b) {
    return a + b;
}

int main() {
    cout << add(5, 10) << endl; // Calls the int version
    cout << add(5.5, 10.5) << endl; // Calls the template version
    return 0;
}

In this example, the add function is overloaded for both int and a generic type T.

What happens if I try to overload with incompatible types?

If you try to overload functions with incompatible types, the compiler will not be able to determine which function to call, leading to a compilation error. It's important to ensure that the overloads are distinguishable by their parameter types.
