Call by reference, value, and name

Question

I\'m trying to understand the conceptual difference between call by reference, value, and name.

So I have the following pseudocode:

foo(a, b, c)
{
           


        

Answer 1

By value - there is no changes out the function. all your actions vanish when the function finished.

By reference - your actions indeed changes the variables. By name - I've never heard ...

Passing x+1 is not change, just tells to the function 3 instead 2 or etc...
