passing object by reference in C++

Question

The usual way to pass a variable by reference in C++(also C) is as follows:

void _someFunction(dataType *name){ // dataType e.g int,char,flo         


        

Answer 1

Passing by reference in the above case is just an alias for the actual object.

You'll be referring to the actual object just with a different name.

There are many advantages which references offer compared to pointer references.
