the function behaves as the value it returns .
for example you can do

int a = func(3,3) + 2;
cout<<a;
output 8.

Answer 2

as the name says itself, it returns the value of a variable, or operation.

if you call the function like:

func(2,3);

and inside it say return a + b, the return value will be 5.

Answer 3

It means you substitute every call of that function for the value it returns.
