Q Can I combine arrays?
A Yes. With simple arrays, you can use pointers to combine them into a new, larger
array. With strings, you can use some of the built-in functions, such as strcat,to
combine strings.
Q Why should I create a linked list if an array will work?
A An array must have a fixed size, whereas a linked list can be sized dynamically at
runtime. Appendix E provides more information on creating linked lists.
Q Why would I ever use built-in arrays if I can make a better array class?
A Built-in arrays are quick and easy to use, and you generally need them to build
your better array class.
Q Is there a better construct to use than arrays?
A On Day 19, “Templates,” you learn about templates as well as the Standard
Template Library. This library contains templates for arrays that contain all the
functionality you will generally need. Using these templates is a safer alternative to
building your own.
Q Must a string class use a char *to hold the contents of the string?
A No. It can use any memory storage the designer thinks is best.Workshop ............................................................................................................
