Help with a program in C(searching for a string).

Hello.

I've been given an assignment to write a program in C that can open a txt file and search for a string. It must then print the lines in which the string was found.

I have the following code so far:

Code:

#include <stdlib.h>

#include <stdio.h>

#include <string.h>

#include <ctype.h>

#include <conio.h>



main()



{



int i=0;

int line=1;

char s1[8]="Networks";

char s2[8]="networks";

char c,a[8];

FILE *fpt;



if((fpt=fopen("C:\\Keimeno.txt","r"))==NULL)

   printf("\nERROR - cannot open the file ");

else

    while ((c=fgetc(fpt))!=EOF)

     {

        if (c=='\n')

           line=line+1;



        a[i]=c;

        i++;



        if(i==8)

          {

          i=0;

          if((strcmp(a,s2)==1)||(strcmp(a,s1)==1))

          printf("The string was found in line %d...\n\n",line);

          }

      }

system("pause");

}

Although the program detects the line change in the text file, it prints that the string was found in almost every line.
I would really appreciate it if someone helped me with this.

The problem was already solved in another forum. I want to apologize for cross-posting,
but the matter was urgent and I needed an answer fast.

As a sign of responsibility, I will post the solution here:

[IMG]file:///C:/DOCUME%7E1/Raz/LOCALS%7E1/Temp/moz-screenshot-1.png[/IMG]Requinix from the Dev Shed Forums and JackOfAllTrades from Dreamincode forums noted that strcmp returns 0 if the string matches, not 1, which was my mistake.

Also my version of the program doesn't detect the string unless it's at some multiple of 8 characters from the beginning of the line.
