Thread: Read from file and match the password and username

Code:

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

int main()
{
   FILE *dg;
   int No1,No2;
   int username,password;
 
   if( (dg=fopen("ogr.txt","r")) == NULL )
     puts("File can not open !\n"), exit(1);
  
   printf("type username :"); scanf("%d",&username); printf("\n");
   printf("type password :"); scanf("%d",&password); printf("\n");
  

   while( !feof(dg) )                  
   {
      fscanf(dg,"%d %d",&No1,&No2);

      if((No1==username) && (No2==password))
      {
         printf("Correct Numbers");
      }
      else
      {
         printf("Wrong Numbers");
      }
   }

   fclose(dg);                          

 return 0;
}

error message :
ubuntu@ubuntu-desktop:~/Desktop/Debug$ cc readf.c -o 5

if I cancel this part if((No1==username) && (No2==password))
code is working, what can be the errors?

I believe that stray /something means an illegal character. Usually from copying pasting.
Try typing again the line.
Read also the FAQ about feof()

One of those symbols is not as they appear, then, in your source file. If I remember correctly, those \xxx things are actually octal, but anyway they represent special characters.

Thnx for urgent reply

I will change the algortihm
