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.

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

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

In this example, the add function is overloaded for different types.

What are the benefits of using function overloading in templates?

The benefits include improved code readability, reusability, and the ability to handle different data types seamlessly without needing to write multiple functions for each type.

Are there any limitations to function overloading in templates?

Yes, one limitation is that the compiler may have difficulty resolving overloaded functions if the types are too similar, leading to ambiguity errors.
