My first quistion

[adelkhamis]

Hi every body..
I've corrected my code in which I would like to compare strings of two txt files;

file1.txt=
054,8100,171
054,8100,191


file2.txt=
054,8100,171
054,8100,191
054,8100,171
054,8100,181
054,8100,171
054,8100,171
054,8100,171

to be as following:

Code:

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<conio.h>

void pError(char * s){
   printf("%s\n",s);
}

int main(){

int equal_lines=0;
FILE *pt1,*pt2;
pt1=fopen("file1.txt","r");
if (pt1==NULL)
   pError("open error f1");
pt2=fopen("file2.txt","r");
if (pt2==NULL)
   pError("open error f2");

short q=0;
char c1[50],c2[50]; //declaring a string to hold the content of each file.
int buf_size=sizeof(c1);

fgets(c1,buf_size,pt1);
while(((fgets(c2,buf_size,pt2))!= NULL)&&(!q))
   {
        printf("f1: %s\n",c1);
        printf("f2: %s\n",c2);


         if(strcmp(c1,c2)==0)
           equal_lines++;


   }

printf("\n\n equal_lines=%d",equal_lines);
getch();
return 0;
}

untill this point, it's perfectly achieve comparing 1st string of file1 with all strings of file2...
but know, I want to compare the 2nd string of file1 with all string of file2.. and so on consecutively..

I would greatly appreciate it if I could get some assistance! Thanks in advance!

Just before/at/instead of line 25 you need a loop similar to line 26 that operates on file 1.
