堆和栈的区别可以用如下的比喻来看出：

使用栈就象我们去饭馆里吃饭，只管点菜（发出申请）、付钱、和吃（使用），吃饱了就走，不必理会切菜、洗菜等准备工作和洗碗、刷锅等扫尾工作，他的好处是快捷，但是自由度小。

使用堆就象是自己动手做喜欢吃的菜肴，比较麻烦，但是比较符合自己的口味，而且自由度大。

-Difference between heap and stack can use the following analogy of view out: use the stack as we go to a restaurant for dinner, just order (an application), pay, and eat (use), enough to go, do not have to bother to cut dishes, vegetables, and other preparatory work and washing dishes, scrubbing pots off the work of his advantages are speed, but the small degree of freedom. Using heap like yourself to do the dishes you like to eat too much trouble, but more in line with their own tastes, and freedom.
