Strategies
- Know what your program should do.
- Does your program do what's
expected?
- Before you inspect a variable, decide what
value is should have.
- If value is correct, look elsewhere for the
bug.
- If value is incorrect, double check your
computation, then try to find out why your program comes up with a
different value.
- Look for off by one errors.
- Look for computation errors (is the formula
typed in correctly).
- Make "sign calculations" when the numbers get
nasty. ("Should this number be positive or negative?")
