How does function overloading work in programming languages?

How does function overloading work in programming languages?

Function overloading allows multiple functions to have the same name but different parameters. It helps in creating more readable and maintainable code.

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

In Python, you can achieve function overloading using default parameters or by using variable-length arguments. For example:

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

Here, add can take one or two arguments.

What are the benefits of using function overloading?

The benefits include improved code readability, easier maintenance, and the ability to use the same function name for similar operations, which can reduce confusion.

Are there any programming languages that do not support function overloading?

Yes, some programming languages like Go and JavaScript do not support function overloading in the traditional sense, but they have other ways to achieve similar functionality.
