What is function overloading in C++ templates?

Can you explain what function overloading in C++ templates is?

Function overloading in C++ templates allows you to define multiple functions with the same name but different parameter types or numbers. This enables more flexible and reusable code.

How does it differ from regular function overloading?

In regular function overloading, the functions must have different parameter types or counts. In templates, the same function can work with different data types, making it more versatile.

Can you give me an example of function overloading in templates?

Sure! Here's a simple example:

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

int main() {
    cout << add(5, 3); // Calls add<int>
    cout << add(5.5, 2.5); // Calls add<double>
}

What are the benefits of using function overloading in templates?

The benefits include code reusability, type safety, and the ability to handle different data types with a single function definition.
