【c语言】把student a am i 变成 i am a student

// 把student a am i 变成 i am a student
//思想：把每个单词翻转，然后再把整体翻转

#include <stdio.h>
#include <string.h>
//把每次解析出来的单词翻转
 void fanw( char *l,char *r )
{
	char* left = l;
	char* right = r;
	char temp;
	while( left < right )
	{
		temp = *left;
		*left = *right;
		*right = temp;
		left++;
		right--;
	}
}
//解析出来每个单词
void fans( char *p )
{
	
	while( *p != '\0')
	{
		char *pst = p;
		while( *p != '\0' && *p != ' ' )
		{
			p++;
		}
		fanw( pst,p-1 );
		p++;
	}
}

int main()
{
	char p[30] = "student a am i";
	int len = strlen(p);
	printf("原字符串是：%s\n",p);
	printf("翻转后的字符串是：");
	fanw(p,p+len-1);
	fans(p);
	printf("%s\n",p);
	return 0;
}
