What are some examples of function overloading in different programming languages?

Function overloading allows multiple functions with the same name but different parameters. For example, in C++, you can have:

1. void print(int i);
2. void print(double d);
3. void print(string s);

Each function performs a similar action but with different types of input.

Can you give me an example in Python?

Python doesn't support function overloading in the traditional sense, but you can achieve similar behavior using default arguments or variable-length arguments. For instance:

def add(a, b=0):
    return a + b

Here, add can take one or two arguments.

What about Java? How does it handle function overloading?

In Java, function overloading is straightforward. You can define multiple methods with the same name but different parameter lists. For example:

public void display(int a) {}
public void display(String b) {}
public void display(int a, String b) {}

Each method can be called based on the argument types.

Are there any languages that don't support function overloading?

Yes, some languages like Go do not support function overloading. In Go, each function must have a unique name, which can lead to different design patterns to achieve similar functionality.
