void ReverseOrder(char* s)
{
	char temp;
	int len = strlen(s); 
	for(int i = 0,j = len-1;i<j;i++,j--)
	{
		temp = s[i];
		s[i] = s[j];
		s[j] = temp;
	}
}


int main()
{
    char s[] = "123456";
    cout << s << " 长度:" << strlen(s) << endl;
    ReverseOrder(s);
    cout << s << " 长度:" << strlen(s) << endl;
}

注意只能定义为char s[] = "123456"; 在堆栈区。
