RangedRandDemo方法显示如何在指定范围内生成随机数.您只需要范围0 .. 9999.
仅供参考:使用rand() % 10000 将给出该范围内的数字，但是它们不会均匀分布.对于这个游戏"问题，可能没关系.

The RangedRandDemo method shows how to generate random numbers over a specified range. You just want the range 0 .. 9999.
FYI: Using rand() % 10000 will give the numbers over that range, but they will not be uniformly distributed. For this "game" problem, that probably doesn''t matter.
