There you go: http://www.learncpp.com/cpp-tutorial/74a-returning-values-by-value-reference-and-address/[^] Found it by searching for "value reference address C++". That wasn't so hard, was it?

Pretty obvious. What does it sound like to you?

Hello everybody! In my understanding In pass by value new copy is created. In pass by reference is passed but this reference does not occupy space in memory. in pointer address is stored inside a pointer and then this pointer variable is passed. This new variable take space in memory. Pointer can be a null-pointer while a reference always refers to a valid object.
