In computer programming, a forward reference is a reference to an item not yet fully known at the point when the forward reference is required.

The classic example would be that of a tree or list node structure of type Node, which itself contains elements which are pointers to Node elements. For a linked list, these elements might be pointers to previous and next nodes in the list, for a tree, those might point at right and left descendants.

What do you mean by forward declarations in c plus plus?

A forward declaration is simply a declaration of an identifier that will be defined at a later point during compilation. It is quite common to separate declarations from their definitions using header files (.h) and source files (.cpp). The header essentially contains all the forward declarations of all the definitions contained in the source file. It is also common practice to use forward declarations when a header contains pointers to a type, rather than references. If it includes references, then you must include the header file for those references, but if they are pointers then you only need a forward declaration of the type (before it is used) and the actual header that contains the full declaration can be included in the source file instead.
