请使用VC6或使用【答题】菜单打开考生文件夹proj2下的工程proj2，此工程包含有一个源程序文件proj2．cpp，其中定义了Stack类和ArrayStack类。 Stack是一个用于表示数据结构“栈”的类，栈中的元素是字符型数据。Stack为抽象类，它只定义了栈的用户接口，如下所示：公有成员函数功能 push 入栈：在栈顶位置添加一个元素 pop 退栈：取出并返回栈顶元素 ArrayStack是Stack的派生类，它实现了Stack定义的接口。ArrayStack内部使用动态分配的字符数组作为栈元素的存储空间。数据成员maxSize表示的是栈的最大容量，top用于记录栈顶的位置。成员函数push和pop分别实现具体的入栈和退栈操作。请在程序中的横线处填写适当的代码，然后删除横线，以实现上述功能。此程序的正确输出结果应为： a，b，C C，b，a 注意：只在指定位置编写适当代码，不要改动程序中的其他内容，也不要删除或移动“//料found”。 //proj2．cpp include＜iostream＞ using namespacc std； class Stack{ public： virtual void push(char C)=0； virtual char pop=0； }；
