Chapter 5 ■ Programs with Repetition Logic
6. Assume that the fixed charge and the rate per unit are the same for all customers
and are given on the first line. This is followed by the data for the customers. Each
set of data consists of two lines: a name on the first line and the meter readings
on the second line. The “name” xxxx ends the data. Print the information for the
customers under a suitable heading. Also,
• Count how many customers were processed
• Print the total due to the electricity company
• Find the customer whose bill was the highest
7. A file contains data for several persons. The data for each person consists of their
gross salary, deductions allowed and rate of tax (e.g., 25, meaning 25%). Tax is
calculated by applying the rate of tax to (gross salary minus deductions). Net pay is
calculated by gross salary minus tax.
Under an appropriate heading, print the gross salary, tax deducted, net pay, and the percentage
of the gross salary that was paid in tax.
For each person, the data consists of two lines: a name on the first line and gross salary,
deductions allowed and rate of tax on the second line. The “name” xxxx ends the data. Also,
• Count how many persons were processed
• Print totals for gross salary, tax deducted and net pay
• Find the person who earned the highest net pay
8. Write a program that reads several lengths in inches and, for each, converts it to
yards, feet and inches. (1 yard = 3 feet, 1 foot = 12 inches). For example, if a length
is 100, the program should print 2 yd 2 ft 4 in. Choose an appropriate endof-data
marker.
9. Each line of data in a file consists of two lengths. Each length is given as two
numbers representing feet and inches. A line consisting of 0 0 only ends the data.
For each pair of lengths, print their sum. For example, if the lengths are 5 ft. 4
in. and 8 ft. 11 in., your program should print 14 ft. 3 in. The line of data for this
example would be given as
5 4 8 11
10. You are given a file containing an unknown amount of numbers. Each number
is one of the numbers 1 to 9. A number can appear zero or more times and can
appear anywhere in the file. The number 0 indicates the end of the data. Some
sample data are:
5 3 7 7 7 4 3 3 2 2 2 6 7 4 7 7
2 2 9 6 6 6 6 6 8 5 5 3 7 9 9 9 0
Write a program to read the data once and print the number that appears the most in
consecutive positions and the number of times it appears. Ignore the possibility of a tie.
For the above data, output should be 6 5.
