C++ Overloading vs Templates

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 an 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 do templates work in C++?

Templates allow you to write a function or class that can work with any data type. For example:

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

You can call print(5) or print("Hello").

Which one should I use in my project?

It depends on your needs. Use overloading for specific types and templates for generic programming. Consider code readability and maintainability.
