1、常用各种数据校验方法源代码BorlandC++Builder5.0//-----------------------------------------------------------------------------//定义数据类型缩写形式typedefunsignedcharuchar;//无符号字符typedefunsignedshortushort;//无符号短整型typedefunsignedlongulong;//无符号长整型typedefunsignedintuint;//无符号整型typedefDynamicArrayTByteDy

2、nArray;//动态定义字节数组//CRC8位校验ucharCRC8Valid(constuchar*puchData,intlen){ucharcrc8=0;while(len--){crc8=crc8^(*puchData++);}returncrc8;}//---------------------------------------------------------------------------//CRC8位校验ucharCRC8Valid(constTByteDynArraypuchData,intlen){ucharcrc8=0;intinde

3、x=0;while(len--){crc8=crc8^puchData[index++];}returncrc8;}//---------------------------------------------------------------------------//和校验ucharSumValid(constuchar*puchData,intlen){ucharcrc8=0;while(len--){crc8=crc8+(*puchData++);}returncrc8;}//----------------------------------------

4、-----------------------------------//和校验ucharSumValid(constTByteDynArraypuchData,intlen){ucharcrc8=0;intindex=0;while(len--){crc8=crc8+puchData[index++];}returncrc8;}//---------------------------------------------------------------------------//从第index位开始进行校验ucharSumValid(constuchar*pu

5、chData,intindex,intlen){ucharcrc8=0;puchData+=index;while(len--){crc8=crc8+(*puchData++);}returncrc8;}//---------------------------------------------------------------------------//从第index位开始进行校验ucharSumValid(constTByteDynArraypuchData,intindex,intlen){ucharcrc8=0;intindexs=0;indexs+=i

6、ndex;while(len--){crc8=crc8+puchData[indexs++];}returncrc8;}//---------------------------------------------------------------------------//CRC16校验ushortCRC16Valid(constTByteDynArraybuffer,intlen){ushortcrc=0,tmp;intindex=0;while(len--){tmp=buffer[index++];crc=crc^(tmp<<8);for(inti=0;i<

7、8;i++){if(crc&0x8000)crc=(crc<<1)^0x1021;elsecrc<<=1;}}crc=(crc>>8)

8、(crc<<8);return(crc);}//---------------------------------------------------------------------------//CRC16校验ushortCRC16Valid(constuchar*buffer,intlen){ushortcrc=0,tmp;while(len--){tmp=*buffer++;crc=crc^(tmp<<8);for(i
