C++ question on Classes/ objects

[code builder]

For some reason they thought it will be a smart to exams online and not the answers.

I'm stuck on this question
What is a Class C++
I'm stuck between
A class is an object definition
A class is proper way to implement OOP.


I think it's the first one, but i know that classes have objects function at the end of their function not sure if objects are included in definition.

while classes are used in implementing OOP.

Help !!
