本文介绍了一个程序设计问题——如何将输入的多条句子顺时针旋转90度进行输出。文章通过示例详细解释了输入输出的具体形式，并提供了一段C语言实现代码，帮助读者理解如何逐字符处理并完成旋转任务。

In ``Rotating Sentences,'' you are asked to rotate a series of input sentences 90 degrees clockwise. So instead of displaying the input sentences from left to right and top to bottom, your program will display them from top to bottom and right to left.

Input and Output

As input to your program, you will be given a maximum of 100 sentences, each not exceeding 100 characters long. Legal characters include: newline, space, any punctuation characters, digits, and lower case or upper case English letters. (NOTE: Tabs are not legal characters.)

The output of the program should have the last sentence printed out vertically in the leftmost column; the first sentence of the input would subsequently end up at the rightmost column.

Sample Input

Rene Decartes once said,
"I think, therefore I am."

Sample Output

"R
Ie
 n
te
h 
iD
ne
kc
,a
 r
tt
he
es
r
eo
fn
oc
re
e
 s
Ia
 i
ad
m,
.
"

wrong了N次不知为何，终于水过了，学会了用fgets知道了他会把回车符也读入。一直习惯于eof结束，fgets好吧学会了

#include <stdio.h>
#include <string.h>
#define size 200
void main ()
{int l,i,j,t,k=0,max=0;
char s[size][size];
while (fgets(s[k],size-1,stdin))
k++;
for (i=0;i<k;i++)
{t=0;
while (s[i][t]!='\n') ++t;
if (t>max) max=t;
for (j=t;j<size;j++)
s[i][j]=' ';
}
for (i=0;i<max;i++)
{for (j=k-1;j>=0;j--)
printf("%c",s[j][i]);
printf("\n");
}
}
