Pointers in C++

Using typedefs

Rather than referring to gameState pointers as type gameState*, we can use the C++ typedef declaration to simplify:

struct gameStateInfo { int pile1; int pile2; }; typedef gameStateInfo* gameState;

Here, gameState is defined to be the name for the type gameStateInfo*, where gameStateInfo is the actual struct type.

Now, no mention of asterisks needs to be made in functions.

void clear(gameState g) { g->pile1 = 0; g->pile2 = 0; }
