Case 2 Robert wants to design a program for ordering pizza. He has completed a flowchart that illustrates how the computer should proceed through the instructions in the final program. The shape, price, and size of the pizza are presented as input. The output expresses which pizza is the best deal after being asked for a decision on the input. He has also created a UML (Unified Modeling Language) diagram. Before finalizing the algorithm for the pizza computer program, how will Robert know his algorithm is correct?
A) Perform a walkthrough using actual code
B) Perform a walkthrough using pseudocode
C) Perform a walkthrough using a verbal presentation to a group of programmers
D) both b and c

Question

Quizplus · Accepted Answer

Performing a walkthrough using pseudocode (option B) or a verbal presentation to a group of programmers (option C) can help identify any logical errors or areas of confusion. This can help ensure the algorithm is correct before actual code is written. Therefore, the best choice is both options B and C. Performing a walkthrough using actual code (option A) would be time-consuming and inefficient before testing the algorithm with simpler methods.
