can anyone tell me to create a program that can tell the difference between to dates. Even leap years? I really need help. I have been trying to do it for the past two weeks and I still get errors.

Helps to post exactly what you're having problems with.

Would this be your homework ? If you've been trying for two weeks, you must have some code you can post ? Christian I have drunk the cool-aid and found it wan and bitter. - Chris Maunder

The normal approach is to convert the dates into some numeric format, from which you can then perform the subtraction and convert back to days, weeks etc. In Windows you would normally set up a SYSTEMTIME structure, convert it to a FILETIME with SystemTimeToFileTime, copy the two parts of FILETIME into a LARGE_INTEGER, then do 64-bit arithmetic on the QuadPart member. A FILETIME is in 100ns (0.1us, or 1 x 10 ^ -7 s) intervals. If the code needs to be portable (e.g. to work on Unixes) you might prefer looking at the C standard library routines, the tm structure and the time_t numeric type.
