What's the difference between a library and function?

Question

I have been seeing these words on my guide but don't have a clear understanding. If possible please provide examples

Answer 1

@chirag answer is wrong.
a function is a set of instructions that can be executed by calling the function, example:
int sum(int a, int b) {
return a+b;
}
main () {
cout<<sum(5,3); //outputs 8
}
A library is usually a set of classes and functions that are made by other people to make your like easier, for example c++ comes with the standard library which contains classes for input and output, data stream, containers and orther utilities. There are also third-party libraries like the boost library or sfml

Answer 2

@Chirag meaning libraries act as a container of functions?

Answer 3

@Marco thanks I now fully have an idea

Answer 4

Functions are meant to do a specific task.

Libraries contain the predefined functions provided by the programming language.
