sqstack

代码说明：

  和线性表类似，栈也有两种存储表示：顺序栈和链栈。 　　顺序存储结构简称为顺序栈。和顺序表类似，对顺序栈也需要事先为它分配一个可以容纳最多元素的存储空间。 (and linear scale similar Stack also have two storage : order Stack and Stack chain. Sequence storage structure referred to as the sequence of stack. Table and order similar to the order Stack also needs prior to allocate it can accommodate a maximum of elements of storage space.)
