A static library is linked with the main program when the program is ..............

What are the pros of using dynamic libraries rather than static?

• More efficient algorithms used

• An algorithm only needs to be updated once

• Better use of memory space

• They are more secure

What are the cons of using dynamic libraries rather than static?

• Malware could be introduced by swapping out a DLL file

• If a DLL file is lost the program may no longer work

• Worse use of memory space

• They are less secure

What are advantages of using libraries?

• Less memory space needed

• Less development time needed

• More secure

• Code will be well tested
