Problem Solving Tasks for Loops
For each of the following problems go through the formal process of determining Data Input(s), Data Output(s), Data Processes, drawing up a Data Table and an Algorithm.
- Develop an algorithm for a program that will repeatedly accept as data input a customer's surname, forename, and middle initial (separately), and display forename, middle initial, and surname. The user will finish by typing 'QUIT' as the surname, eg:
Please type the surname of customer : Stonk
Please type the forename of customer : Hank
Please type the middle initial of customer : P
Customer Name : Hank P Stonk
- Develop an algorithm for a program that will repeatedly calculate the SUM and the PRODUCT of three numbers entered at the keyboard. The end of data will be a first number of 99.
- Develop an algorithm for a program that will repeatedly work out an employee's net pay. The number of hours worked, and the hourly rate of pay are entered at the keyboard. Assume that a constant tax of £30 is deducted for everyone. The last employee will be indicated by a negative number of hours.
- Develop an algorithm for Sunny Day Tours that will work out the cost of a family holiday. The program should accept as data input the number of adults and number of children in the party. The program should calculate the hotel bill at £60 per adult, and £20 per child, and calculate the fare as £210 per adult, and £110 per child. The program should display the total holiday cost. The loop will be terminated by data input of 0 for number of adults.
- Develop a program that will take in a temperature in degrees Centigrade and convert it into degrees Fahrenheit, and will display degrees Fahrenheit. The formula to convert Centigrade to Fahrenheit is: Fahrenheit = (Centigrade * 9/5) + 32. Amend the algorithm so that the program will continue to convert temperatures until the user types a negative value for Centigrade.
- Develop an algorithm that will convert the number of ounces entered (Integer) into the equivalent value in pounds and ounces and display the equivalent values. (16 ounces = 1lb). Note: The following prompt is to be displayed on screen: 'Do you wish to convert a number of ounces? (Y/N)'. The program should continue to convert ounces into pounds and ounces while the reply to the prompt is 'Y'.
