-'''Pointers''' are special in C++. '''Pointers''' can be used to point to a [[variable]] instead of becoming a variable.
-Here is an example:
-There are 5 [[integer]] [[variable]]s.
-Each one is named accordingly (anInteger1, anInteger2, ect)
-However we have a [[function]] that uses whatever [[integer]] the user chooses.
-Enter '''pointer'''s.
-When running the program, the user makes his choice to pick whatever [[integer]] he wants.
-When that happens, the '''pointer''' is pointed twoard that [[integer]].
-Finally, whenever the user is ready, he will continue to the next stage, where a [[function]] is run to return the value of the [[integer]] he has chosen.
-The function will automatically pick whatever [[integer]] we have the '''pointer''' aimed at.
