经典的三次翻转：1.先翻转字符串前n个字符；2.再翻转后面的字符；3.翻转整个字符串；比如：输入字符串s="12345abc"，n=5;首先翻转前5个字符变成54321abc，然后翻转后面的字符变成54321cba，最后翻转整个字符串变成abc12345。#include <stdio.h>#include <windows.h>#include <string....

对指针进行加1，其实就是加上其指向类型的大小。struct B {              long lA1;              char cA2;              char cA3;              long lA4;              long lA5;       }*p;       p = (struct B*)0x1000000;       //...
