Use Code Libraries
uYou aren’t the only one who will need to use the code.
ØCode is often rewritten dozens of times.
ØCode should be well documented and placed for easy reuse.
uCode should be placed in a code library and referenced each time it is used
ØMakes code less prone to errors
ØEvery time a piece of logic is rewritten, code will be written slightly differently. This can cause code errors that are very difficult to find.
uLarge systems usually contain hundreds of reusable components
ØDivide them into logical packages to avoid losing track of them.
