1. (TCO 10) A retail store is having a customer appreciation sale. Depending on the total dollars purchased, the customer could receive a discount on his or her total purchases. You are to develop pseudocode that will obtain the total dollars purchased from the user, determine the discount percentage, and display the total amount due. When the purchases are more than $100, the discount is 10%. When the purchases are $100 or less, the discount is 5%. (Points : 10) 2. (TCO 10) A small business in your neighborhood would like an application developed that determines the average dollar amount spent for every three purchases. The user will enter three different purchase amounts. You need to display the average to your client. Complete the pseudocode to design your logic. (Points : 10) 3. (TCO 9 & 10) There is a logic error in the following pseudocode. The loop needs to execute four times. What statement(s) would you need to add or change to correct the logic? Be sure to explain why you are adding or changing the statements. Set REPEAT Set + 1 UNTIL total <> EndWhile Display total (Points : 10) 4. (TCO 4 & 10) Complete the pseudocode by rewriting the algorithm. The design is determining the correct sales tax depending on the county identifying code. Counties with a number less than 10 have a 6% sales tax. The 11–25 codes have a sales tax of 7%. Codes above 25 have a sales tax of 8%. The code is entered by the user. Begin Declare Real salesTax Declare _____ countyCode _____ “Enter the county code: “ _____ countyCode If _____ <= 10=""> Set Else If _____ AND _____ then Set Else _____ EndIf _____ Display “the sales tax is: “ + _____ End (Points : 10)
5. (TCO 5 & 10) Complete the pseudocode by rewriting the algorithm. The design is to display a 60-second countdown. Begin Declare _____ count Set REPEAT Display “countdown: “ + _____ Set - 1 UNTIL _____ EndDo Display “LIFT OFF!” End (Points : 10) 6. (TCO 4, 5 & 10) Complete the pseudocode by rewriting the algorithm. The colors red, blue, and yellow are known as primary colors because they cannot be made by mixing other colors. When you mix two primary colors, you get a secondary color. Mixing yellow and blue gets you green. Mixing red and blue gets you purple. The algorithm allows the user to enter two primary colors and then displays the resulting secondary color. The colors entered by the user will be validated to ensure they entered a primary color. Begin Declare String color1 Declare String color2 Declare String control1 Declare String control2 _____ “Enter first primary color: “ Input _____ Prompt “Enter the second primary color: “ Input _____ Set control1 = “n” DOWHILE control1 = “n” If (color1 <> “yellow”) _____ (color1 <> “red”) _____ (color1 <> “blue”) then Prompt “first primary color is invalid” Input _____ Else Set control1 = “y” ENDO Set control2 = “n” DOWHILE control2 = “n” If (color2 <> “yellow”) _____ (color2 <> “red”) _____ (color2 <> “blue”) then Prompt “second primary color is invalid” Input color2 Else Set control2 = “y” ENDO
If (color1 = “red”) AND (_____) then Display “secondary color is: purple” EndIf If (color1 = “yellow”) AND (_____) then Display “secondary color is: green” EndIf End (Points : 10) 7. (TCO 1, 2, 3, & 4) Describe the difference between a flowchart and pseudocode and explain whether one is more important to develop than the other. (Points : 10) 8. (TCO 1, 2, 3, 4, & 5) Describe two of the three control structures and how relational and logical operators are used. (Points : 10)
