括号匹配算法：

#include <stdio.h>//括号匹配
int main() {char str[7]={'{','(',')','[',']','}'};char data[10];int top=-1;char elements;bool flag= true;for (int i = 0; i < 7; ++i) {if (str[i]=='('||str[i]=='['||str[i]=='{'){data[++top]=str[i];}if (str[i]==')'||str[i]==']'||str[i]=='}'){if (top==0){flag= false;}elements=data[top--];if (str[i]==')'&&elements=='('){printf("()匹配成功\n");}if (str[i]==']'&&elements=='['){printf("[]匹配成功\n");}if (str[i]=='}'&&elements=='{'){printf("{}匹配成功\n");}}}return 0;
