Downloaded from hlayiso.com SCENARIO Your school as commissioned you as the IT learner to help manage the media centre. The media centre offers services to the learners and the teachers as follows: > Borrowing and returning to library books and educational DVD's. > Use of the internet per time. : > Photocopying and printing. QUESTION ONE [SCRATCH PROGRAMMING] ~ 40 Minutes The media centre requires each learner to have a code which is a randomly generated seven digit code. This code when entered by the user must be tested. Open the application in Scratch called Quest1. You will find that there are four sprites created. Complete the script to validate the code entered by the user as requested below: © Two lists have been created for you. You are required to declare all other variables that you may need to complete the application. Hint: Study this script isan example to help solve the problem. 1.1. The sprite on the left(Input Sprite) should accept the data from the table below and store it in the required lists. You should only enter the details for the number of names suggested by the user. Do not enter the entire table. The capturer should ask the user to enter the number of names he wants to test, followed by the name list and the code list. Program the sprite using loops to populate the respective lists with the data from the table as specified by the user. (10) NAME CODE Rodanne 1232414 René 3147238 _| Preleen 8365389 Trevor 4236891 Réann 7642531 Jonathan 5627819 Page 2 of 7

Downloaded from hlayiso.com 1.2. Write the scripts for the respective sprites that will validate the codes in the given list. 1.2.4. The second sprite (on the right) helps in the validation process by doing the following: Extracts the middle number from the code list. * Determines if the number is prime or not and sets a variable called “prime” to equal to “true” or “false” respectively. (12) 1.2.2. The third sprite will also assist the validation process by: “Extracting every value in an even index position and accumulate a sum for these values. “The sum of the first and the last digits in the code must also be added. + It then checks to see if the two sums are the same and assigns the value “true” if they are or “false” if they are not. (10) 1.2.3. The last sprite simply displays the following: ** The name of the person entered, the code entered for that person and the “Valid” or “Invalid” according to the results e.g. of output: Rodanne , 1232414 , VALID! (4) Use the picture of the scratch code: Hey guys! Im Hello im Testing the sums. HiT am the Input Guy! Hilm testing the [4 prime for you! [36] Page 3 of 7

Downloaded from hlayiso.com : QUESTION TWO [JAVA PROGRAMMING] 40 minutes You are requested to develop apps to assist in the management of the media centre. The first app that your help is required in is the app designed by the learners to aid the process of calculating charges for the photocopier. The school has a pricing system based on the grades and the number of copies made, for each learner and teacher that may use the system. Educators will only pay for colour copies as stated below. The learners will pay as follows: GRADE 8 AND 9 © 50c per copy for <=15 copies An additional 30c is charged for every copy more than 15 *For every copy more than 50copies, an additional R1 is charged. GRADE 10 AND 11 ©80c for every copy <=25 copies. *Additional 50c per copy for more than 25 copies #R1,20 is charged for every copy over 50 copies GRADE 12 The first 15 copies is free ( ) *From 16 to 35 copies, a charge of R1.10 is charged per copy *An additional cost of 50c per copy is charged for copies above 35 Nb. Each colour copy costs R4 per colour copy. Colour copies are only made for teachers. Open the project June2015G10 and execute the Q1Frame. The program has no functionality. insert your name as a comment in the first line of each class. Study the GUI below and complete the code for the respective buttons and components. 2.1. Program the components in the Data Entry panel as follows: 2.1.1. Format the jPanel3 to a border entitled Quotation. (3) 2.1.2. Set the spinner in the from 0 to 100, type integer, using the properties window. (3) 2.1.3. Set the combo box to select the grade(8 ~ 13) as integers. (3) 2.1.4, Initialise the radio buttons into the same group. (3) 2.1.5. Place a title at the top of jPanel1 that reads: “Photocopy Application” (3) Page 4 of 7

Downloaded from hlayiso.com 2.2. Declare the global variables for the following data entries in the Q1Frame class. (3) Name of Identifier Type Description numCopies. Integer value | The number of copies made by the client — accessed from spinner ger Integer A value in the range 8 to 13 — combo box selection. Nb. 13 represents a teacher name Text The name of the client —jTextfield numBlack Integer The number of black copies made — jTextfield numCol Integer The number of colour copies. 2.3, Write code, for the CAPTURE DATA button in the Data Entry panel, that assigns the values upon entry to the global variables. Note: ¥ The number for colour must be entered only if Colour radio button is selected. v If Black/White is selected, the number is taken from the text field on the top. v Ifa learner selects a colour photocopy, display a suitable message to ask them to reselect. 2.4, Program the PROCESS button to calculate the price that the client must pay. Take note of the following: > Teachers will only pay for colour copies. Black and white copies are free for teachers. Therefore the number of copies for teachers will be for colour only. Use the sample run below: a ae 3 = ea JA Auote 5 = a He ieeges tty NANE MR Naldoo See ee Sa TEACHER = a NUM of Slack Copies NUM of Colnur Copies 5 PRICE 720.00 MR Diaidoo Page 5 of 7

Program the Print Quote button in the Quotation panel to display the output as shown in the sample run. _ (5) NAME nilel TEACHER NUM of Black Copies 2 NURl of Colour Copies 3 PRICE, sR20,00 [40] QUESTION THREE [40 minutes] Learners who use the Internet have to be given a rating category. Each learner-is given a code which is made up of their Last name and four digits e.g. “Pillay8540”. The four digit code consists of: > The number of times the person used the internet out of 100, i.e. the first two digits. This must be a two digit number. > The second two digits is a randomly generated number from ten to ninety nine. 3.1. You are required to complete the application that allows the user to enter his/her last name and the number of times they used the internet as a single string e.g. “Pillay85”, Then you should join the randomly generated number to the other input e.g. “Pillay8540” where 40 is generated. Form the code and display it in the appropriate textfield given. (8) 3.2. The rating of the learner depends on the first two digits after the last name. The rating is worked out as follows: Value Rating 0<=Value<30 D 30<=Value<50 c 50<=Value<70 B 70<=Value<=100 A Page 6 of 7

Use the code formed to extract the number of times the internet was used. (4) 3.2.2. Use the of times to determine the rating(assume the number of times represents a %) according to the rating table given above.
