Searching Files

[smmcc]

I've looked everywhere and havent been able to find a solution. I have a file that holds the account number and the balance of the account. I want the user to enter the account number and the program tests to see if it is there and returns the balnace. I have tried figuring this out using text files and binary files but havent been able to figure it out yet

Any help would be greatly appreciated.

Try:

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

int findinfile(char *lookforme){
       FILE *in;
       int i,found;
       char *big;
       in=fopen("filename","rb")
       fseek(in,0,SEEK_END);
       i=(int) ftell(in);
       big = calloc(1+i,1);
       fread(big,i,1,in);
       found =0;
       if (strstr(big,lookforme) != NULL)
          found = 1;
       fclose(in);
       return found;

}
