Construct a solution algorithm for the following programming problems. To obtain your final solution, you should:
• define the problem
• group the activities into modules (also consider the data that each module requires)
• construct a hierarchy chart
• establish the logic of the mainline using pseudocode
• develop the pseudocode for each successive module in the hierarchy chart
• desk check the solution algorithm.
The Tidy Phones Telephone Company’s charges file contains records for each call made by its Metroville subscribers during a month. Each record on the file contains the subscriber’s name and phone number, the phone number called, the distance from Metroville of the number called (in kilometres) and the duration of the call (in seconds).
Design a program that will read the Tidy Phones charges file and produce a telephone charges report, as follows:
The cost of each call is calculated as follows:
Main headings and column headings are to be printed on the report, allowing 45 detail lines per page. The total revenue line is to be printed three lines after the last detail line.
We need at least 10 more requests to produce the solution.
0 / 10 have requested this problem solution
The more requests, the faster the answer.
