Function Overloading vs Templates in C++

What is the difference between function overloading and templates in C++?

Function overloading allows multiple functions with the same name but different parameters, while templates enable generic programming by allowing functions and classes to operate with any data type.

Can you give me an example of function overloading?

Sure! Here's a simple example:

void print(int i) {
    std::cout << "Integer: " << i << std::endl;
}

void print(double d) {
    std::cout << "Double: " << d << std::endl;
}

This allows you to call print(5) or print(5.5).

And how about an example of templates?

Certainly! Here's a template function example:

template <typename T>
void print(T value) {
    std::cout << "Value: " << value << std::endl;
}

You can call print(5) or print("Hello") with this template.

When should I use function overloading instead of templates?

Use function overloading when you have specific implementations for different types, and templates when you want a single implementation for multiple types.
