Write routines to implement two stacks using only one array. Your stack routines should not declare an overflow unless every slot in the array is used. Format of functions: Stack CreateStack( int MaxElements ); int IsEmpty( Stack S, int Stacknum ); i…

从语法上,在C++中(仅仅讨论C++中).class和struct做类型定义时仅仅有两点差别: (一)默认继承权限. 假设不明白指定,来自class的继承依照private继承处理.来自struct的继承依照public继承处理: (二)成员的默认訪问权限. class的成员默认是private权限,struct默认是public权限. 除了这两点.class和struct基本就是一个东西.语法上没有不论什么其他差别. 不能由于学过C就总认为连C++中struct和class都差别非常大,以下列…
