You're comparing the address of the strings, not the content of the
strings.  Use strcmp.
Replace this line:
   }while (gets(i) != password);
with this:
   }while (!strcmp(gets(i), password));
In C strings are arrays of characters, and arrays are pointers.  Net
result:  strings are pointers.  If you say string1 = string2; and then
say string1[0] = 'a'; you'll find that string2s first character is now
also 'a'.
