(完整word版)进程管理实验报告源代码
实验一进程管理1．目的和要求通过实验理解进程的概念，进程的组成（PCB结构），进程的并发执行和操作系统进行进程管理的相关原语（主要是进程的创建、执行、撤消）。
2．实验内容用C语言编程模拟进程管理，至少要有：创建新的进程；查看运行进程；换出某个进程；杀死运行进程以及进程之间通信等功能。
3．实验环境Windows操作系统、VC++6.0C语言4．实验提示PCB结构通常包括以下信息：进程名，进程优先数，轮转时间片，进程所占用的CPU时间，进程的状态，当前队列指针等。
可根据实验的不同，PCB结构的内容可以作适当的增删。

经典C语言程序100例(word文档版)
【程序1】题目：有1、2、3、4个数字，能组成多少个互不相同且无重复数字的三位数？都是多少？1.程序分析：可填在百位、十位、个位的数字都是1、2、3、4。
组成所有的排列后再去掉不满足条件的排列。
2.程序源代码：main(){int i,j,k;printf("\n");for(i=1;i<5;i++) ／*以下为三重循环*/for(j=1;j<5;j++)for (k=1;k<5;k++){if (i!=k&&i!=j&&j!=k) /*确保i、j、k三位互不相同*/printf("%d,%d,%d\n",i,j,k);}}=========================================================== 【程序2】题目：企业发放的奖金根据利润提成。
利润(I)低于或等于10万元时，奖金可提10%；利润高于10万元，低于20万元时，低于10万元的部分按10%提成，高于10万元的部分，可可提成7.5%；20万到40万之间时，高于20万元的部分，可提成5%；40万到60万之间时高于40万元的部分，可提成3%；60万到100万之间时，高于60万元的部分，可提成1.5%，高于100万元时，超过100万元的部分按1%提成，从键盘输入当月利润I，求应发放奖金总数？1.程序分析：请利用数轴来分界，定位。
注意定义时需把奖金定义成长整型。
2.程序源代码：main(){long int i;int bonus1,bonus2,bonus4,bonus6,bonus10,bonus;scanf("%ld",&i);bonus1=*0.1;bonus2=bonus1+*0.75;bonus4=bonus2+*0.5;bonus6=bonus4+*0.3;bonus10=bonus6+*0.15;if(i<=)bonus=i*0.1;else if(i<=)bonus=bonus1+(i-)*0.075;else if(i<=)bonus=bonus2+(i-)*0.05;else if(i<=)bonus=bonus4+(i-)*0.03;else if(i<=)bonus=bonus6+(i-)*0.015;elsebonus=bonus10+(i-)*0.01;printf("bonus=%d",bonus);}=========================================================== 【程序3】题目：一个整数，它加上100后是一个完全平方数，再加上168又是一个完全平方数，请问该数是多少？1.程序分析：在10万以内判断，先将该数加上100后再开方，再将该数加上268后再开方，如果开方后的结果满足如下条件，即是结果。

增量式PID控制C语言代码
增量式PID控制公式：
上面△u(k)是控制量增量，“增量式PID”就是直接以这个增量进行控制。
至于参数的整定，根据响应的情况调，比如，响应慢了，我就增大kp，或者减小kd，超调大了就减小kp或增大点kd，这个规律你可以看看PID三个参数的作用：）
////////////////////////////////////////////////////////////////
{
memset ( pp,0,sizeof(PID));
//memset()的函数，它可以一字节一字节地把整个数组设置为一个指定的值。
// memset()函数在mem.h头文件中声明，它把数组的起始地址作为其第一个参数，
//第二个参数是设置数组每个字节的值，第三个参数是数组的长度(字节数，不是元素个数)。

CRC16校验C语言程序源码(附完整的可执行的C语言代码)
CRC16校验C 语言程序源码 （附完整的可执行的 C 语言代码）//CRC16校验在通讯中应用广泛，这里不对其理论进行讨论，只对常见的 2种//实现方法进行测试。
方法一：查表法（256长度的校验表）速度快，准确，但是对于单片机设备存储占用大，且校验表长度大，输入时容易岀现错误 // .................. --POPULAR POLYNOMIALS ....................// CCITT: x A 16 + x A 12 + x A 5 + x A 0(0x1021) // CRC-16: x A 16 + xA15 + xA2 + xA0(0x8005)#defi neCRC_16_POLYNOMIALS0x8005const BYTE chCRCHTalbe[]=// CRC 高位字节值表{0x00, 0xC1, 0x81, 0x40, 0x01, OxCO, 0x80, 0x41, 0x01, OxCO, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x00, 0xC1,0x81,0x40, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x00, 0xC1, 0x81, 0x40, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x00, 0xC1,0x81,0x40, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41,0x00, 0xC1,0x81,0x40,0x01, 0xC0, 0x80, 0x41,0x01,0xC0, 0x80, 0x41, 0x00, 0xC1,0x81,0x40, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x00, 0xC1,0x81,0x40, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x00, 0xC1, 0x81, 0x40, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x00, 0xC1, 0x81, 0x40,0x01,0xC0, 0x80, 0x41,0x01, 0xC0, 0x80, 0x41,0x00, 0xC1, 0x81, 0x40, 0x01, 0xC0,0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x00, 0xC1, 0x81, 0x40, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x01,0xC0, 0x80, 0x41,0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x00, 0xC1,0x81,0x40, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x00, 0xC1, 0x81, 0x40, 0x01, 0xC0, 0x80, 0x41, 0x00, 0xC1, 0x81, 0x40, 0x01,0xC0, 0x80, 0x41, 0x01,0xC0, 0x80, 0x41,0x00, 0xC1, 0x81, 0x40 }；con st BYTE chCRCLTalbe[] = // CRC 低位字节值表 {0x00, 0xC0, 0xC1,0x01,0xC3, 0x03, 0x02, 0xC2, 0xC6, 0x06, 0x07, 0xC7,0x05, 0xC5, 0xC4, 0x04, 0xCC, 0x0C, 0x0D, 0xCD, 0x0F, 0xCF, 0xCE, 0x0E, 0x0A, 0xCA, 0xCB, 0x0B, 0xC9, 0x09, 0x08, 0xC8, 0xD8, 0x18, 0x19, 0xD9, 0x1B, 0xDB, 0xDA, 0x1代 0x1E, 0xDE, 0xDF, 0x1F, 0xDD, 0x1D, 0x1C, 0xDC, 0x14, 0xD4, 0xD5, 0x15, 0xD7, 0x17, 0x16, 0xD6, 0xD2, 0x12, 0x13, 0xD3, 0x11, OxD1, OxDO, 0x10, OxFO, 0x30, 0x31, OxF1,0x33, 0xF3, 0xF2, 0x32, 0x36, 0xF6, 0xF7, 0x37, 0xF5, 0x35, 0x34, 0xF4, 0x3C, 0xFC, 0xFD, 0x3D,0xFF, 0x3F, 0x3E, 0xFE, 0xFA, 0x3A, 0x3B, 0xFB, 0x39, 0xF9, 0xF8, 0x38,0x28, 0xE8, 0xE9, 0x29, 0xEB, 0x2B, 0x2A, 0xEA, 0xEE, 0x2E, 0x2F, 0xEF,0x2D, 0xED, 0xEC, 0x2C, 0xE4, 0x24, 0x25, 0xE5, 0x27, 0xE7, 0xE6, 0x26,0x22, 0xE2, 0xE3, 0x23, 0xE1, 0x21, 0x20, 0xE0, 0xA0, 0x60, 0x61,0xA1,0x63, 0xA3, 0xA2, 0x62, 0x66, 0xA6, 0xA7, 0x67, 0xA5, 0x65, 0x64, 0xA4,0x6C, 0xAC, 0xAD, 0x6D, 0xAF, 0x6F, 0x6E, 0xAE, 0xAA, 0x6A, 0x6B, 0xAB,0x69, 0xA9, 0xA8, 0x68, 0x78, 0xB8, 0xB9, 0x79, 0xBB, 0x7B, 0x7A, 0xBA,0xBE, 0x7E, 0x7F, 0xBF, 0x7D, 0xBD, 0xBC, 0x7C, 0xB4, 0x74, 0x75, 0xB5,0x77, 0xB7, 0xB6, 0x76, 0x72, 0xB2, 0xB3, 0x73, 0xB1, 0x71, 0x70, 0xB0,0x50, 0x90, 0x91, 0x51, 0x93, 0x53, 0x52, 0x92, 0x96, 0x56, 0x57, 0x97,0x55, 0x95, 0x94, 0x54, 0x9C, 0x5C, 0x5D, 0x9D, 0x5F, 0x9F, 0x9E, 0x5E,0x5A, 0x9A, 0x9B, 0x5B, 0x99, 0x59, 0x58, 0x98, 0x88, 0x48, 0x49, 0x89,0x4B, 0x8B, 0x8A, 0x4A, 0x4E, 0x8E, 0x8F, 0x4F, 0x8D, 0x4D, 0x4C, 0x8C,0x44, 0x84, 0x85, 0x45, 0x87, 0x47, 0x46, 0x86, 0x82, 0x42, 0x43, 0x83,0x41, 0x81, 0x80, 0x40}；WORD CRC16_1(BYTE* pchMsg, WORD wDataLe n){BYTE chCRCHi = 0xFF; // 高CRC字节初始化BYTE chCRCLo = 0xFF; // 低CRC字节初始化WORD win dex; // CRC 循环中的索引while (wDataLe n--){// 计算CRCwin dex = chCRCLo A *pchMsg++ ;chCRCLo = chCRCHi A chCRCHTalbe[wl ndex]; chCRCHi =chCRCLTalbe[wi ndex];}return ((chCRCHi << 8) | chCRCLo);}方法一：列表法(简单表)con st WORD wCRCTalbeAbs[]={0x0000, 0xCC01, 0xD801, 0x1400, 0xF001, 0x3C00, 0x2800, 0xE401, 0xA001, 0x6C00, 0x7800,0xB401,0x5000, 0x9C01,0x8801,0x4400,}；WORD CRC16_2(BYTE* pchMsg, WORD wDataLe n){WORD wCRC = OxFFFF;WORD i;BYTE chChar;for (i = 0; i < wDataLe n; i++){chChar = *pchMsg++;wCRC = wCRCTalbeAbs[(chChar A wCRC)& 15] A (wCRC>> 4);wCRC = wCRCTalbeAbs[((chChar >> 4) A wCRC) & 15] A (wCRC >> 4);}return wCRC;}方法二：定义法根据CRC16/MODBUS理直接计算，算法简单但对单片机计算压力大。
