Code for PROGRAM TO COMPARE TWO STRINGS USING LOOP SPLITTING in C Programming

#include <stdio.h>
#include <string.h>
#include "headfork.h"
#include "headsem.h"
#include "headshr.h"

main()
{
    int i,nprc,id,shmid1,shmid2,shmid3,*final,flg=0;

}

OUTPUT

knoppix@ttyp0[pp]$ cc comp_str_lps.c
knoppix@ttyp0[pp]$ ./a.out
Enter first string : college

Enter second string : college

Enter the no.of proc: 3

Strings are equal

knoppix@ttyp0[pp]$ cc comp_str_lps.c
knoppix@ttyp0[pp]$ ./a.out
Enter first string : college

Enter second string : vasad

Enter the no.of proc: 3

Strings are not equal
