合工大编译原理实验报告,后面附代码,孩纸,只能参考不能抄袭哦,好好学习天天向上,

class stack//栈的构造及初始化 {

public:

bool empty() const;//是否为空 bool full() const;//是否已满

bool get_top(char &c)const;//取栈顶元素 bool push(const char c);//入栈 bool pop();//删除栈顶元素 void out();//输出栈中元素 ~stack(){}//析构 private:

int count;//栈长度

char data[MaxLen];//栈中元素 };
