#include <stdio.h>
void reverse(char* s)
{
// 获取字符串长度
int len = 0;
char* p = s;
while (*p != 0)
{
len++;
p++;
}
// 交换 ...
int i = 0;
char c;
while (i <= len / 2 - 1)
{
c = *(s + i);
*(s + i) = *(s + len - 1 - i);
*(s + len - 1 - i) = c;
i++;
}
}
int main()
{
char s[] = "www.codercto.com";
printf("'%s' =>\n", s);
reverse(s); // 反转字符串
printf("'%s'\n", s);
return 0;
}
以上实例输出结果为：
'www.codercto.com' => 'moc.boonur.www'
