换行输出HDU1088:Write a simple HTML Browser
题记：写这篇博客要主是加深自己对换行输出的认识和总结实现算法时的一些验经和训教，如果有错误请指出，万分感谢。
Problem Description
If you ever tried to read a html document on a Macintosh, you know how hard it is if no Netscape is installed.
Now, who can forget to install a HTML browser? This is very easy because most of the times you don't need one on a MAC because there is a Acrobate Reader which is native to MAC. But if you ever need one, what do you do?
Your task is to write a small html-browser. It should only display the content of the input-file and knows only the html commands (tags) <br> which is a linebreak and <hr> which is a horizontal ruler. Then you should treat all tabulators, spaces and newlines as one space and display the resulting text with no more than 80 characters on a line.

Then you should treat all tabulators, spaces and newlines as one space and display the resulting text with no more than 80 characters on a line.
Input
The input consists of a text you should display. This text consists of words and HTML tags separated by one or more spaces, tabulators or newlines.
A word is a sequence of letters, numbers and punctuation. For example, "abc,123" is one word, but "abc, 123" are two words, namely "abc," and "123". A word is always shorter than 81 characters and does not contain any '<' or '>'. All HTML tags are either <br> or <hr>.

Output
You should display the the resulting text using this rules:
. If you read a word in the input and the resulting line does not get longer than 80 chars, print it, else print it on a new line.
. If you read a <br> in the input, start a new line.
. If you read a <hr> in the input, start a new line unless you already are at the beginning of a line, display 80 characters of '-' and start a new line (again).
The last line is ended by a newline character.
. If you read a word in the input and the resulting line does not get longer than 80 chars, print it, else print it on a new line.
. If you read a <br> in the input, start a new line.
. If you read a <hr> in the input, start a new line unless you already are at the beginning of a line, display 80 characters of '-' and start a new line (again).
The last line is ended by a newline character.
Sample Input
Hallo, dies ist eine ziemlich lange Zeile, die in Html aber nicht umgebrochen wird. <br> Zwei <br> <br> produzieren zwei Newlines. Es gibt auch noch das tag <hr> was einen Trenner darstellt. Zwei <hr> <hr> produzieren zwei Horizontal Rulers. Achtung mehrere Leerzeichen irritieren Html genauso wenig wie mehrere Leerzeilen.
Sample Output

题意：1.涌现<br>换行
2.涌现<hr>输出‘-’
3.每一行的加上现在的单词如果长度超过80则换行，每一个单词前留一个空格
4.结束时要输出换行
解法：知道了题意以后，就是很简单的标题了，注意处理就可以了
#include <stdio.h>
#include <string.h>
int main()
{
char s[10000];
int len;
int cnt = 0;
while(~scanf("%s",s))
{
if(!strcmp(s,"<br>"))
{
cnt = 0;
printf("\n");
}
else if(!strcmp(s,"<hr>"))
{
if(cnt)
printf("\n--------------------------------------------------------------------------------\n");
else
printf("--------------------------------------------------------------------------------\n");
cnt = 0;
}
else
{
int len = strlen(s);
if(!cnt)
{
cnt = len;
printf("%s",s);
}
else if(cnt+len+1>80)
{
cnt=len;
printf("\n%s",s);
}
else
{
cnt+=len+1;
printf(" %s",s);
}
}
}
printf("\n");
return 0;
}
文章结束给大家分享下程序员的一些笑话语录： 关于编程语言
如果 C++是一把锤子的话，那么编程就会变成大手指头。
如果你找了一百万只猴子来敲打一百万个键盘，那么会有一只猴子会敲出一 段 Java 程序，而其余的只会敲出 Perl 程序。
一阵急促的敲门声，“谁啊！”，过了 5 分钟，门外传来“Java”。
如果说 Java 很不错是因为它可以运行在所有的操作系统上，那么就可以说 肛交很不错，因为其可以使用于所有的性别上。
