1、实验1-1 过程化编程【实验目的】理解、掌握过程化编程程序设计思想。【实验内容】1. 程序填空，练习类、对象、继承的定义和实现方法。2. 根据程序运行结果，补充完整程序。【实验要求】我们在进行英语阅读的时候，会发现一个有趣的现象：有些字串是左右对称的，如madam。我们把这种字串称为symmetry text 即“对称文”。现在有若干航字串，每一行可以由数字、标点符号、空格符以及英文字符（包括大小写）组成。要你帮忙编程判断是否是对称文，否则，就不能最大限度地发现有趣现象了。输入说明每个字串为一行，每行结束以回车符为标志，可能有上百上千行业说不定。当字串为“000000”时，输入结束。英文字符不

2、区分大小写，即Madam亦为对称文。不要忘了“”也是互为对称的。输出说明如果是对称文，则输出“Symmetry”，否则输出“Not symmetry”。每个结论占一行。图 1 symmetry.in1 / 20图 2 symmetry.out【程序代码】#include#includeusing namespace std;bool isMatch(string s);int main() string s;while (1) cin s;if (pare(000000) = 0) break;if (isMatch(s) cout Symmetry endl;else cout Not sy
