What are comparator functions in C++?

Can you explain what comparator functions are in C++?

Sure! Comparator functions in C++ are used to define custom sorting criteria for algorithms like sort().

How do I create a comparator function?

You can create a comparator function by defining a function that takes two parameters and returns a boolean value.

Can you give me an example of a comparator function?

Absolutely! Here's a simple example: bool compare(int a, int b) { return a < b; } This will sort integers in ascending order.

What if I want to sort in descending order?

You can modify the function to return a > b instead. This will sort the integers in descending order.
