I don't have notes which cover these Qs which is silly. But here are the Qs:

1- The Software Develoment process is to be ITERATIVE in nature. What does this term mean?
2- If a local variable is used in a program where in the program is it declared?
3- Give an advantage of using local variable in your program.
4- What is meant by the term "String Variable"?
5- A programmer requires to take the contents of 2 string variables, combine them and store them into a single string. What is the name given to this technique?
6- A programmer requires to take one individual letter from 2 string variables, combine them and store them into a single string. What is the name given to this technique?


*If you all can answer some of these Qs it'll be ok, as I will need to get notes from my school. As it's wrong not to give notes then give hards Qs.

1) Iterative means to repeat, so the process is interative because steps are gone back to and done again as things change

2) local variable are declared in procedures and functions

3) local variables cannot be manipulated by other procedures so another procedure cannot accidently interfere with your procedure and cause a bug in the program

4) String variable is a variable containing text

5) concatenation

6) erm not sure here, to take out parts of a string is to take a substring and to put them together in a variable is concationation


Erm these answers are a bit rough but it gives you something to work from at least and the answers are there

I think the answer to 6 is concatenation (not sure of the spelling, Dave's could be correct.

I think that's when you have variables first_name$ and surname$

And the concatenation would be going :-

name$ = first_name$ + surname$

no 6 is definately Concatenation, as i remember getting something similar like that either in class or in an exam/prelim

Array indexing might be a part of the answer for the last one...

Just a thought.

I'm not really sure about the definitive answer for the last one. I know concatenation was added into the course last year. But like many questions there will be more than one acceptable answer.

Guess what the answer was for the last one, it was substrings lol
