First, by saying if(month==january)you are comparing to variables.  if(month=="january") would be correct,
but to compare strings you have to use 
if (strcmp("january",month)){
instead.  Also, you have spelt prinf wrong on the february bit, but that is just a little mistake.
Hope it works now, but I haven't checked it.
