小程序（七）C语言 输入字符 检测后每个单词逆序输出

比如说，输入 He  is a boy.

那么，输出 eH si a yob.

#include<stdio.h>
#include<stdlib.h>


void comp(char * inputStr, int len , char *outputStr)
{
    char *temp = (char*)malloc(sizeof(char)*len);

	int cont = 0;
	int n = 0;
	
	while(*inputStr)
	{
		while(*inputStr != ' ' && *inputStr != '\0')//不是空格的就把它存到temp中
		{
			temp[n] = *inputStr++;
		    cont++;
			n++;
		}
		
			
			for(int i=cont-1;i>=0;i--)
			{
				*outputStr++ = temp[i];//将temp中的元素逆序存入outputStr
			
			}
			if(*inputStr!='\0')
			  *outputStr++ = ' ';
			inputStr++;
			cont = 0;
			n = 0;
		
		//flag = 1;
	}
    *outputStr = '\0';

	   //printf("%s\n",outputStr);
}






int main()
{
  char * s = "  He is a boy   ";
  char *c = s;
  int len = 0;
  while(*c++)
      len++;
  char * outputStr = (char*)malloc(sizeof(char)*(2*len));
  comp(s,len,outputStr);
  printf("%s\n",outputStr);
  getchar();
  return 0;

}
