[Uva] Tex Quates (272)
UVA - 272
Description TeX is a typesetting language developed by Donald . If the source contained "To be or not to be," quoth the bard, "that is the question." then the typeset document produced by TeX would not contain the desired form: ``To be or not to be," quoth the bard, ``that is the question." In order to produce the desired form, the source file must contain the sequence: ``To be or not to be,'' quoth the bard, ``that is the question.'' You are to write a program which converts text containing double-quote (") characters into text that is identical except that double-quotes have been replaced by the two-character sequences required by must be replaced by ``, the next by '', the next by ``, the next by '', the next by``, the next by '', and so on. Input Input will consist of several lines of text containing an even number of double-quote (") characters. Input is ended with an end-of-file character. Output The text must be output exactly as it was input except that:
Sample Input "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!" Sample Output ``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!'' |

ac代码：
#include <cstdio>
using namespace std;
int main(){
int c;
bool flag = 1;
while(scanf("%c", &c) != EOF)
if (c == '"') {printf("%s", flag ? "``":"''"); flag = !flag;}
else printf("%c", c);
return 0;
}
题目比代码长n倍典型范例 :)
