Debugging: Run-time Errors
|
Mistakes the compiler doesn't catch (the hardest problems to solve sometimes)
cin/cout outputs wrong number of items or just
completely skips some
- Check that you have arrows, not commas, between every 2
items (variables, strings, function calls, etc., all count as
separate items.
- Loop or decision statement doesn't work
- Check for semicolons at the end of a loop or decisiont statement.
They don't belong there (
if, do, while, for, etc.
do not take a semicolon at the end of the line)!
switch/case statement 'bleeds' from one case to
the next
- There must be a
break; at the end of every case
in a switch() block.
- Wrong answer to a seemingly correct formula
- Remember operator precedence! Start by adding lots of
parentheses--it can't hurt to have a lot of them! This
is especially important in complex formulas where the
precedence may be obvious to you, but not to the
compiler.
