第1章　声明和初始化基本类型1.1　我该如何决定使用哪种整数类型？1.2　为什么不精确定义标准类型的大小？1.3　因为C语言没有精确定义类型的大小，所以我一般都用typedef定义int16和int32。
然后根据实际的机器环境把它们定义为int、short、long等类型。
这样看来，所有的问题都解决了，是吗？1.4　新的64位机上的64位类型是什么样的？指针声明1.5　这样的声明有什么问题？char*p1,p2;我在使用p2的时候报错了。
1.6　我想声明一个指针，并为它分配一些空间，但却不行。
这样的代码有什么问题？char*p;*p=malloc(10);声明风格1.7　怎样声明和定义全局变量和函数最好？1.8　如何在C中实现不透明(抽象)数据类型？1.9　如何生成“半全局变量”，就是那种只能被部分源文件中的部分函数访问的变量？存储类型1.10　同一个静态(static)函数或变量的所有声明都必需包含static存储类型吗？1.11　extern在函数声明中是什么意思？1.12　关键字auto到底有什么用途？类型定义(typedef)1.13　对于用户定义类型，typedef和#define有什么区别？1.14　我似乎不能成功定义一个链表。
我试过typedefstruct{char*item;NODEPTRnext;}*NODEPTR;但是编译器报了错误信息。
难道在C语言中结构不能包含指向自己的指针吗？1.15　如何定义一对相互引用的结构？1.16　Struct{　}x1;和typedefstruct{　}x2;这两个声明有什么区别？1.17　“typedefint(*funcptr)();”是什么意思？const限定词1.18　我有这样一组声明：typedefchar*charp;constcharpp;为什么是p而不是它指向的字符为const?1.19　为什么不能像下面这样在初始式和数组维度值中使用const值？constintn=5;inta[n];1.20　constchar*p、charconst*p和char*constp有什么区别？复杂的声明1.21　怎样建立和理解非常复杂的声明？例如定义一个包含N个指向返回指向字符的指针的函数的指针的数组？1.22　如何声明返回指向同类型函数的指针的函数?我在设计一个状态机，用函数表示每种状态，每个函数都会返回一个指向下一个状态的函数的指针。
可我找不到任何方法来声明这样的函数——感觉我需要一个返回指针的函数，返回的指针指向的又是返回指针的函数……，如此往复，以至无穷。
数组大小1.23　能否声明和传入数组大小一致的局部数组，或者由其他参数指定大小的参数数组？1.24　我在一个文件中定义了一个extern数组，然后在另一个文件中使用，为什么sizeof取不到数组的大小？声明问题1.25　函数只定义了一次，调用了一次，但编译器提示非法重声明了。
*1.26　main的正确定义是什么？voidmain正确吗？1.27　我的编译器总在报函数原型不匹配的错误，可我觉得没什么问题。
这是为什么？1.28　文件中的第一个声明就报出奇怪的语法错误，可我看没什么问题。
这是为什么？1.29　为什么我的编译器不允许我定义大数组，如doublearray[256][256]?命名空间1.30如何判断哪些标识符可以使用，哪些被保留了？初始化1.31　对于没有显式初始化的变量的初始值可以作怎样的假定？如果一个全局变量初始值为“零”，它可否作为空指针或浮点零？1.32　下面的代码为什么不能编译?intf(){chara[]="Hello,world!";}*1.33　下面的初始化有什么问题？编译器提示“invalidinitializers”或其他信息。
char*p=malloc(10);1.34　chara[]="stringliteral";和char*p="stringliteral";初始化有什么区别？当我向p[i]赋值的时候，我的程序崩溃了。
1.35　chara{[3]}="abc";是否合法？1.36　我总算弄清楚函数指针的声明方法了，但怎样才能初始化呢？1.37　能够初始化联合吗？第2章　结构、联合和枚举结构声明2.1　structx1{　};和typedefstruct{　}x2;有什么不同？2.2　这样的代码为什么不对？structx{　};xthestruct;2.3　结构可以包含指向自己的指针吗？2.4　在C语言中用什么方法实现抽象数据类型最好?*2.5　在C语言中是否有模拟继承等面向对象程序设计特性的好方法？2.6　为什么声明externf(structx*p);给我报了一个晦涩

#includesbitpwm=P3^7;sbitjia=P3^0;sbitjian=P3^5;sbitled=P3^2;chartt0,zkb;voidinit();voidmain(){ init(); while(1) { if(jia) { ysms(80); if(jia) { zkb--; if(zkb8) { zkb=8; } while(jian); } } if(zkb==8) { TR0=0; pwm=1; } else { TR0=1; } }}voidinit(){ P3M1=0X21; //00100001P350SHURU TMOD=0X01; TH0=0XFF; //6MHZ100uS TL0=0XCE; ET0=1; EA=1; TR0=1; zkb=8; led=0; ysms(200); led=1; ysms(200); led=0; ysms(200); led=1; ysms(200); led=0; ysms(200); led=1; ysms(200); led=0;}voidtime0()interrupt1{ tt0++; if(tt0＞zkb) { pwm=0; } if(tt0＞8) { tt0=0; pwm=1; } TH0=0XFF; //6MHZ100uS TL0=0XCE;}

主要包括一个初始化种子函数voidInitSeed()；
和两个二维随机点生成函数PointStructGetUniformPoint2()；
PointStructGetNormalPoint2()；
函数返回点的坐标。
实现了生成服从二维均匀分布和二维标准正态分布随机点的功能。

oracle的补丁，theplug-infailedinitsperformmethod报错的时候使用

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
