Question 1

What are libraries?

Answer 1

pre-compiled programs which can be incorporated with other programs using either static or dynamic linking

Question 2

Library charatceristics/
advanatges

Answer 2

ready t use and error free, so save time developing and testing modules
+ : can be reused within multiple programs

Question 3

What are Libraries often used for?

Answer 3

to provide a specialised range of functions which woul otherwise require a lot of time and effort to develop

saves programmers from having to ‘reinvent the wheek’ and instead make use of other’ expertise

popular libraries provide mathematical and graphical functions

Question 4

Libraries (exam style)

Answer 4

• standard pieces of software which often perform common tasks such as sorting and searching
• routines are compiled and fit into modularisation of algorithms
• they’re pre-tested so are relatively error-free
• pre-writeeen so ready to use and already available for programmer to use with a new program - saves work and time
• may be used multiple times to reduce repeated code
• may allow programmer to use code which has been written in a different source language
• written by an expert so allows programmer to others’ expertise
