Deliver a question and P10

Can you have a vector of strings

Yes.

Can you return a vector from a function

Yes, but it means copying it and will be inefficient.

Do you have intialize strings

You have to initialize old-fashioned character arrays: char[...].

You don't have to initialize C++ STL strings. If you omit to do it they are set to a string with nothing in it.

What is a scalar

A scalar comes from mathematics -- the opposite of a vector.

In programming a scalar is a single value with no extractable pieces. Thus int, double, char, are all scalars. Arrays, vectors, and objects are not scalars.

When to use recursion vs iteration

Take CS202:-)

Think about the data the function is handling. If it is recursive then a recursive function will be easiest to write. If the data is itterative.... use loops.

Think about the problem. Is it describe recursively -- then use recursion.

1. Elseuse loops.

   Do variables declared in main have a scope after the end of the main function

   No.

   What is an access function

   An access function or accessor is a function in a class that computes and returns a value with out changing the object. They express properties of objects. Examples: get age, get height, get grade,... They are also called getters because their name traditionally starts "get".

   What is a predicate

   A predicate is a function that returns one of the two bool values: true or false. Thats all. The term goes bac to formal logic 2000 years ago!

   Is FOIRTRAN still being used in older equipment like weather satelites

   (1) It can take a lot of time and money to translate a lot of code from one language to another.

   (2) FORTRAN does a good job of scientific computation.

   We have a joke that the programming language used on the Starship Enterprise is called FORTRAN -- but doesn't look anything like 20th Century FORTRAN.

   Who uses UML Diagrams

   Competent proffessionals.

   Can an array have more than two dimensions

   Strickly speaking an array in C++ is always one dimensional.

   But you can combine or nest as many as you need to get higher dimensions. For example to play three-dimensional tic-tac-toe or model a Rubric's Cube you might declare

     	Cubey cube[3][3][3];
