Rotating Sentences

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.

Input

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

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,
.
"

感觉好水啊这题，题目很容易就看懂了，为了搞清楚输入输出细节我借助了google翻译，结果"I think, therefore I am."这句名言变成了刘若英说的，让人捧腹。。。

wa了几次，老会把空格打成a，定义ch数组时老是无法正常定义，遇到a条件输出空格也不行，不知道是错误出在哪里。。

#include<stdio.h>
int main()
{
  int i = 0, j = 0, maxj = 0, maxi;
  char ch[100][100], temp;
  int row[100] = {0};

  for (;(temp = getchar()) != EOF;){
    if (temp == '\n'){
      i ++;
      j = 0;
    }
    else if (temp != '\t'){
      ch[i][j++] = temp;
      if (maxj < j)
        maxj = j;
      row[i] = j;
    }
  }

  maxi = i - 1;
  for (j = 0; j < maxj; j ++){
    for (i = maxi; i >= 0; i --)
      printf("%c", j < row[i] ? ch[i][j]: ' ');
    printf("\n");
  }

  return 0;
}
