CIS17 - Assignment on arrays

Problem #1: I am buying tickets to a show. The two variables are seating on the floor (code 1) or in the balcony (code 2) and the type of production. Productions are assigned a code of 1, 2, or 3 depending on the anticipated demand.

	Production Type 1	Production Type 2	Production Type 3
Floor (code 1)	100	75	50
Balcony (code 2)	80	60	35

In my pseudocode I have the following:

Loop

Move the idno, name and address to the output line

· You need to insert a line of code using subscripts/indexes/pointers that will use the production code on the input (prodCd)on the input and the location code on the input (locCd) to move the price from the array/table to the output line. Lets call the name of the price in the table just price. Tell me whether you are setting up the codes so it will go to the row and then the column or the column and then the row.

Write the line

Read another record

End Loop

• Now using your code tell me the price you would get if the prodCd was 3 and the locCd was 2.
• Now lets assume the data is unreliable. Tell me the if statement or statements you would use to make sure the codes are within the correct range.

Problem #2: The college uses codes like CIC, CIN, CIW, CIB, CIX, CIM, CIT to determine which option the student is in. For this problem assume that the record for the student on the file contains one of these codes and that you want to go to the array/table and print out the name (please note I am not sure I got the codes right - just go with my guesses).

Option Code	Option Name
CIC	Computer Programming
CIN	Computer Networking
CIW	Webmaster
CIB	Business Information Systems
CIX	Computer Science Transfer
CIM	Multimedia and the Internet
CIT	Information Systems Transfer

For our purposes we are going to call the option code on the input optIN, the option code in the array optArray and the option name in the array optName.

You need to write the pseudocode search to take the option code from the input, search the table and write the option name on the output line. If the option does not exist, you want to write an appropriate message to indicate that it was an invalid code.

Extra Credit:

If you changed the order of the option codes and put them in sequential order, you could write an early exit routine that would let you exit when you know that a match cannot be found even though you have not necessarily checked all of the options in the table. Show the revised table and write the pseudocode to handle an early exit.
