题意: 给出两个数字,输出(1)有多少位是相同的(2)有多少位不在正确的位置上. 思路: 扫一遍,统计相同的,并且将两串中不同的数的出现次数分别统计起来,取小者之和就是第2个答案了. class Solution { public: string getHint(string secret, string guess) { ; ,sizeof(int)*N); ,sizeof(int)*N); , wrong=; ; i<secret.size(); i++) { if(secret[i]==g

程序代码中退出函数exit()与返回函数return ()的区别   exit(0):正常运行程序并退出程序:   exit(1):非正常运行导致退出程序:   return():返回函数,若在主函数中,则会退出函数并返回一值.  解析: 1. return返回函数值,是关键字: exit 是一个函数. 2. return是语言级别的,它表示了调用堆栈的返回:而exit是系统调用级别的,它表示了一个进程的结束. 3. return是函数的退出(返回):exit是进程的退出. 4. return是

编写好layout中的接口组件之后,下一步就是编写控制接口组件的程序代码.上一章,我们使用了三种接口组件,在使用者输入性别和年龄之后点击“健康建议按钮”,程序会读取用户所填入的性别和年龄,然后显示判断结果,因此接口组件和程序代码之间必须能够互动并完成下列 3件事: 1.btnDoSug按钮被点击后,程序开始运行判断的程序代码: 2.程序代码必须能够读取edtSex和edtAge这两个EditText组件中的字符串: 3.程序代码必须将最后的判断结果显示在txtResult组件中. (一)设置Bu

具体怎么编译,生成执行程序,不懂得先学习C++程序代码编译和集成开发环境. 多的不说了,只有两个代码文件,一个头文件,一个源文件.不多说了,直接上干货. (恶意使用,或者商用,后果自负,与本人无关.) head.h #pragma once #ifndef WINVER // Specifies that the minimum required platform is Windows Vista. #define WINVER 0x0600 // Change this to the appr

要搞清楚别人的代码,首先,你要了解代码涉及的领域知识,这是最重要的,不懂领域知识,只看代码本身,不可能搞的明白.其次,你得找各种文档:需求文档(要做什么),设计文档(怎么做的),先搞清楚你即将要阅读是什么玩意,至少要把代码的整体结构搞清楚:整体架构如何,有几个模块,模块间通信方式,运行环境,构建工具等等.最后,如果不是全部的代码都归你管,重点关注将会属于你的模块,其他代码了解下即可. 如何快速读懂大型C++程序代码 (2012-06-14 11:25:03) 标签: c编程 分类: C 学习 六
