What is a free function in programming?
A free function is a function that is not associated with any class or object. It's defined independently.
Can you give me an example of a free function?
Sure! In C++, a free function could look like this:
int add(int a, int b) {
return a + b;
}
This function can be called without needing an object.
What are the advantages of using free functions?
Free functions promote code reusability and can be easier to test since they don't depend on class states.
Are there any downsides to using free functions?
One downside is that they can lead to a less organized code structure if overused, especially in large projects.
