Difference between operator and function in C++?

Question

I could use some help understanding the following in C++, particularly the difference between an operator and a function:

• What is an operator?
• What is a f

Answer 1

Here are some differences between an operator and a function:

1. An operator does not push its parameters onto the stack, but a function pushes its parameters onto the stack.

2. The compiler knows about the operation of the operators, but is not aware of the output of the function. Said a different way, the action of the operator is defined at compilation time and that of a function is defined at the runtime.
