UVA272 TEX Quotes【字符串处理】

本文主要是介绍UVA272 TEX Quotes【字符串处理】，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

问题描述

在Tex中，左双引号是 “ `` ”，右双引号是 “ '' ”。输入一篇包含双引号的文章，你的任务是把它转换成TeX的格式

样例输入

"To be or not to be," quoth the Bard, "that
is the question".
The programming contestant replied: "I must disagree.
To `C' or not to `C', that is The Question!"

样例输出

``To be or not to be,'' quoth the Bard, ``that
is the question''.
The programming contestant replied: ``I must disagree.
To `C' or not to `C', that is The Question!''

解题思路：简单字符串处理，问题的关键是如何把 “ '' ” 换成对应的符号，使用一个标记即可，具体看程序

AC的C语言程序：

#include<stdio.h>int main()
{int c,q=1;while((c=getchar())!=EOF){if(c=='"'){printf("%s",q?"``":"''");q=!q; }elseprintf("%c",c);}return 0;}
