c语言写函数实现数组的反转要求用指针可运行？

代码示例：

#include<stdio.h>

void reverse_string(char *string)

{

char*last;

for (last = string; *last !bai= '\0'; last++);

last--;

while (string < last)

{

char temp;

temp = *string;

du *string++ = *last;

*last-- = temp;

}

}

void main()

{

char string[] = "abcdef";

printf("%s\n", string);

reverse_string(string);

printf("%s\n", string);

system("pause");

}
