							Determine if two rectangles overlap each other?
					I am trying to write a C++ program that takes the following inputs from the user to construct rectangles (between 2 and 5): height, width, x-pos, y-pos. All of these rectangles will exist parallel to the x and the y axis, that is all of their edges will have slopes of 0 or infinity.

							Does Java support default parameter values?

This matches C++ syntax, which only allows defaulted parameters at the end of the parameter list.  
Beyond syntax, there is a difference where this has run time type checking for passed defaultable parameters and C++ type checks them dur...

For that reason C & C++ only allow switches on integer types, since it was pointless with other  types.
