3.2 - Defining and Differentiating Computation.  vs ()
I'm trying to get a solid fix on how math computations work in C++ and how to declare their order, in particular with respect to ( ) operators.
this adds to an array:
inventory[numItems++] = "armor".
why don't I need to add () to the calculation? Because it's alone?
inventory[(numItems++)] = "armor"?
I see the () used in a lot of other calculations and I know they have to do with setting order:
num = ((i x 5) + var); //makes sure i is multiplied by 5 before added to var.
Even though the calculation is clear, the entire thing still has to be encasulated within ( ). Right? Why not in the array?
