C语言不使用库函数反转字符串

给定一个字符串，当然你也可以自己输入（更改一下语句）
给定：“student a am i”
输出：“i ma a tneduts”

#include <stdio.h>
int main()
{
	int i = 0;
	int count = 0;
	char stu[] = { "student a am i" };
	char* star = stu;
	while (*star++)
	{
		count++;
	}
	star = stu;
	char* end = stu + count - 1;
	for (i = 0; star < end; i++)
	{
		char temp = *star;
		*star = *end;
		*end = temp;
		end--;
		star++;
	}
	printf("%s", stu);
}
