A company employs workers as: • labourers who are paid $18 per hour • office workers who are paid $22 per hour • managers who are paid $30 per hour. A computer programmer has written part of an algorithm in pseudocode. The completed algorithm will calculate and output the wage for each worker. The inputs will be: • the number of workers • the job code for each worker (L for labourer, O for office worker or M for manager) • the number of hours each worker has worked. If L, O or M is not entered for the job code then the message ‘Invalid job code’ will be output. The algorithm will terminate when all the workers’ details have been entered. It will use the CASE…ENDCASE construct to determine the rate of pay. Complete the algorithm by filling in the missing lines. INPUT number REPEAT INPUT jobcode, hours 'L' : rate count count + 1

A school stores all the records of its students in alphabetical order. Records could be found using sequential access. Explain what is meant by sequential access. The school decides to use the indexed sequential method to search for the records of individual students. An index table contains all the letters of the alphabet in alphabetical order. Describe how the details of a student called Johnsen would be found.
