Fence parts are manufactured by a number of similar machines. The length of the part must fall within a certain range. Parts not within the length range are rejected. The data for each rejected part forms a data packet made up of three data items, each separated by the '/' character delimiter. The format of a data packet is:

text

01<length>/<machine ID>/<description of the fault>

The length is 3 digits (in millimetres).
The machine ID is a single character ('A', 'B', or 'C').
The description of the fault is a variable length string.

A pseudocode program will process the data for several data packets. The program contains the statement:

pseudocode

01DataPacket ← "563/B/the fence length is too long"

Complete the two pseudocode expressions which extract the appropriate data item.

6(b)String HandlingMedium4 marks

The program will create a module RejectDescription() to return the fault description. Write the pseudocode for the module RejectDescription()

6(c)File Handling ExceptionsHard6 marks

The data packets for all rejected parts are saved in this format in a text file Rejects.txt. The file stores one data packet per line. Write pseudocode to:

find all the rejected parts with a length greater than 560 millimetres and that were produced on machine 'B' or machine 'C'
output the description for each matching rejected part.

Your pseudocode will include a module call to RejectDescription() and the answers given for 6(a).
