| | New to classes. Getting alot of errors when calling the private member variables (from down in main). Most are telling me either i can't access the private member variable IDs or the other member variables i'm attempting to access (debit, credit, balance) are undefined ('identifier not found').

| | How can i read in data in different functions without losing the stream's place in the file. i.e function a and function b both open a data stream to read in first and last names from a file. however function b reads in the first name as well rather than …  |
| | i'm looking to get a first name followed by four scores and finally a last name, stored into multiple arrays (a char *array, a float array, & a char *array). getting the scores i understand however the names are pointer arrays. as far that goes what am i doing wrong …  |
| | is there a built in function to deal with numbers similar to how the swap member function (first.swap(second);) deals with strings? thanks |
