You're on a roll — here are the solutions to the questions. 16. (a) State the use of the following flowchart symbols i) The oval symbol (Terminator) is used to indicate the start or end of a flowchart. ii) The rectangle symbol (Process) is used to represent a process or action, such as calculations, assignments, or data manipulation. iii) The diamond symbol (Decision) is used to represent a decision point where a question is asked, and the path of the flowchart depends on the answer (e.g., Yes/No, True/False). 16. (b) Below is an algorithm that is used to compute the values of W, X and Y. Given initial values: A = 10 B = 8 i) Determine the output if the value of M = 2. Step 1: Initialize variables. A = 10 B = 8 Step 2: Input M. M = 2 Step 3: Evaluate the condition IF M >= 25. 2 25 is False. Step 4: Execute the ELSE block. Calculate W: W = A - B = 10 - 8 = 2 Calculate X: X = A = 10 Calculate Y: Y = W × X = 2 × 10 = 20 Step 5: Print the values of W, X, Y. The output is W=2, X=10, Y=20. ii) Determine the output if the value of M = 30. Step 1: Initialize variables. A = 10 B = 8 Step 2: Input M. M = 30 Step 3: Evaluate the condition IF M >= 25. 30 25 is True. Step 4: Execute the IF block. Calculate W: W = A × B = 10 × 8 = 80 Calculate X: X = A + B = 10 + 8 = 18 Calculate Y: (Assuming Y on the right side of the equation refers to an initial value of 0, or it's a typo and should be Y = A + B + W) Y = A + B + W + Y Y = 10 + 8 + 80 + 0 = 98 Step 5: Print the values of W, X, Y. The output is W=80, X=18, Y=98. Got more? Send 'em!
