    Implement On A Data Set of Characters The Three CRC polynomials-CRC 12, CRC 16, CRC CCIP

    Uploaded by

    The document describes a program that implements three CRC polynomials - CRC 12, CRC 16, and CCITT on a data set of characters. The program takes in a frame and generator as input, appends zeros to the frame to match the generator length, and performs CRC calculations by dividing the frame by the generator polynomial. It outputs the processed frame at each step and the final transmitted frame. Sample outputs are given for each CRC polynomial.

    PROGRAM :2

    Aim: Implement on a data set of characters the three CRC polynomials- CRC
    12,CRC 16, CRC CCIP.

    #include<stdio.h>
    #include<conio.h>
    void main()
    {
    char s[100],p[100],d[30];
    int k,len,i;
    clrscr();
    printf("enter frame");
    gets(s);
    printf("enter gen");
    gets(d);
    k=strlen(d)-1;
    len=strlen(s);
    strcpy(p,s);
    for(i=len;i<len+k;i++)
    p[i]='0';
    p[i]='\0';
    printf("msg after appending %d zero bits:",k);
    puts(p);
    printf("order of process is :\n");
    while(strlen(p)>k)
    {
    if(p[0]=='1')
    for(i=0;d[i]!='\0';i++)
    p[i]=(p[i]-'0')^(d[i]-'0')+'0';

    for(i=0;p[i]!='\0';i++)
    p[i]=p[i+1];
    puts(p);
    }
    strcat(s,p);
