Passing By Reference in C++ gives us a few extra little feature ... what is it?

We can pass a pointer by reference allowing us more flexibility in dynamic allocation, unlike C where you have to use multiple pointers to get the same affect Technically we can use a reference parameter to "return" more than one value from a function In C++ we can test for NULL on our reference parameter and deal with it causing less errors Unlike C, passing by reference in C++ is safer and prevents illogical changes to the memory
