It may not be easy. I suggest that you first write functions atoi, atof (conversion from string to int or float). Then have a little practice with va_list (see http://cplusplus.com/reference/clibrary/cstdarg/ ). Lastly, write sscanf (scanf that works with a string rather than console) so that you don't have to deal with input.
