Downloaded from hlayiso.com SECTION C QUESTION FIVE [Solution Development] Information technology learners are subjected to a process of debugging and testing during software design. One of the tools used to achieve this Process is called a trace table. Study the algorithm given below and answer the questions based on it, Line No. 1. Input (num) — - user enters an integer 2. check © true 3. c€2 4, Repeat until c = num 5. if num mod c = 0 then check := false; 6. céc+1 7. end repeat 8. if check = true then Display(‘The number’ num ‘is P') 9. if check = false then Display (‘The number’ num ‘is C’) 5.1. State the type of data stored in the variables: (a) check (b) ¢ (2) 5.2. Use the headings given below to draw up a trace table in your answer books. Show a complete trace of the code above on the trace table for the input value num€ 7. (6) N.B. Start your trace table on a new page so that you will have enough space if necessary. Line | Num Check | C Num mod | c=num? | Display/Output No. c=07? 5.3. State briefly what this algorithm is designed to do. (1) 5.4. What do you think the letters C and P in the output stands for? (2) 5.5. What will be the output for the following inputs: 5.6.1. num€ 51 (1) 5.5.2. num€ 83 (1) 5.6. The school wants to award, at random, a learner with a sponsored prize. There is no criteria specified, so the schoo! decided that instead of drawing from a hat, the interested learners should write down their five-digit admission numbers on a page and submit to office. The winner of the prize will be the first palindrome number received. A palindrome number is a number that is the same value when read backward and forward e.g. 37573. Your task is to write an algorithm to determine and output whether the number is a palindrome or not. (7) N.B. You are not allowed to convert the number to a string/text. You are only allowed to use mathematical(mod, div)/logical operators to produce a solution. [20] Page | 7
