C语言程序设计现代方法第二版 第10章课后编程习题

第一题

这题10.2中的pop函数没有用，在我的电脑里（vs）当把pop赋值给字符串时总是报错，尝试了各种办法都不行，提示是：char(*)()和char类型不兼容。求大神帮呀

#include <stdio.h>#include<string>#define STACK_SIZE 100int top = 0;char contents[STACK_SIZE];void make_empty(void){top = 0;}bool is_empty(void){return top == 0;}bool is_full(void){return top == STACK_SIZE;}void push(char i){if (!is_full())contents[top++] = i;}char pop(void){if (!is_empty())return contents[top--];}int main(void){char ch,temp;int n = 0;printf("Enter parenteses and/or brance:");while ((ch = getchar()) != '\n'){if (ch == '[' || ch == '{')push(ch);else if (ch == ']' || ch == '}'){temp = contents[--top];if (ch == ']'&& temp != '['){n = 1;printf("ch:%c temp:%c\n", ch, temp);}else if (ch == '}'&& temp != '{')n = 1;}}if (n == 1)printf("错误\n");elseprintf("正确\n");system("pause");return 0;}
