What is the difference between default parameters and overloading in programming?

What is the difference between default parameters and overloading in programming?

Default parameters allow you to specify default values for function arguments, while overloading lets you define multiple functions with the same name but different parameters.

Can you give me an example of default parameters?

Sure! In Python, you can define a function like this: def greet(name, greeting='Hello'): return f'{greeting}, {name}!'. Here, 'greeting' has a default value.

And how does overloading work?

Overloading is common in languages like Java. You can have multiple methods named 'add' that take different types or numbers of parameters, like add(int a, int b) and add(double a, double b).

Are there any languages that don't support overloading?

Yes, some languages like JavaScript do not support method overloading in the traditional sense, but you can achieve similar behavior using default parameters or by checking argument types.
