| | Probably because MS chose to make long double and double the same thing. A long double is IIRC only 80 bits (10 bytes), but to preserve alignment, the compiler rounds out the size to a multiple of 4. The underlying architecture isn't the whole story. Running crusty old 16-bit turboc … |
| | Re: help needed.. My first suggestion would be to read up on functions, and then split main() into something more manageable (say 1 function per top-level menu option). Several hundred lines of poorly indented code isn't good to read. |
