Re: [Dev-C++] Class question

The error means that inside a conditional statement (like "if then =
else") the compiler has detected that one of the branches is not =
returning any value.

Note: If you use more return statements in a row, only the first one =
will be executed. Returning 3 variables in the way you do is not =
possible. Alternatives are:
- use a class or struct
- use separate functions for dd, mm and yy
- use system clock notation (dd:m:yy are coded in an unsigned long)

  I am learning how to create a class and I need help.  After creating =
