9.52 使用stack对象处理带圆括号的表达式.遇到左圆括号时,将其标记下来.当你在一个左括号之后遇到右圆括号时,弹出stack对象中这两边括号之间的元素,直到遇到左括号,将左括号也一起弹出栈. 接着在stack对象中压入一个值,用以表明这个用一对圆括号括起来的表达式已经被替换. 程序如下: #include<iostream> #include<stack> #include<string> using namespace std; int main() { sta
#include<stdio.h> main() { int a; printf("请输入一个数字\n"); scanf("%d",&a); switch(a) { case 1:printf("M\n"); break; case 2:printf("T\n"); break; case 3:printf("W\n"); break; case 4:printf("TH\n&
