The "%s" format string does not imply that a colon is not part of a 
"string". You probably want something like

   while (fgets(temp,120,fp)) {
      if (2 != sscanf(temp,"%[^:]:%[^:]",sent[x].name, sent[x].passwd))
         printf("error in line %d\n", x + 1);
      ++x;
   }

If you want to use C, and not a language that was designed for this kind
of work, you can use scan sets. They are portable, as long as you have
an ANSI C compiler.
