Student Average Program: Problem Statement And Requirements

The Student Average Program Problem Statement and Requirements

Plan and design the algorithm logic of the “Student Average” program using IPO analysis and the Raptor tool. The following are the functional requirements:

  • The program shall allow the user to enter the student’s ID, student’s name, and student’s mid-term and final exams grades.
  • The program shall compute the student’s total.
  • The program shall compute the student’s average grade.
  • The program shall display a report card showing the student ID, name, total, and average.

ASSUMPTIONS AND CONSTRAINTS

  1. The maximum rating for each exam is 100 points.
  2. The average is calculated by adding the two grades and then dividing them by 2.
  3. The average must be displayed in percentage format.
  4. The assignments for which the average is calculated can vary in number and type; however, in this version of the program, the program logic is limited to handling two assignments only and of the same type (exams); a mid-term and final exams.
  5. The report card shall not contain the student name.
  6. The program may handle more than one student; however, in this version of the program, the program logic is limited to handling one student at a time.
  7. The structure used to compose the computation is a sequence structure. Other structures will be covered in subsequent assignments.

REQUIREMENTS

  1. Algorithm analysis leading to an IPO Chart
  2. Algorithm planning leading to a Pseudocode
  3. Algorithm design and evaluation leading to Flowchart

Paper For Above instruction

The development of a student average program entails a systematic approach comprising IPO analysis, pseudocode planning, and flowchart design using Raptor. This comprehensive process ensures a clear understanding of the problem, an effective algorithm, and an accurate visual representation of the program logic.

Firstly, the IPO (Input-Process-Output) chart provides a high-level overview of the program's fundamental operations. Inputs encompass the student ID, name, and exam grades. The processing phase involves calculating the total scores and deriving the average. Outputs include a report card displaying the student ID, name, total, and average, with emphasis on clarity and correctness.

For the input, the program prompts the user to enter the student’s ID, name, mid-term grade, and final exam grade. The process then sums the two grades to obtain the total and computes the average by dividing this total by two. The average is then formatted as a percentage value. The output presents a report card with the specified details, excluding the student’s name according to the constraints. Since the program handles only one student per execution, the logic is straightforward and employs sequence structures to maintain process flow.

Next, the pseudocode provides a step-by-step logical plan that guides the implementation of the program. The pseudocode begins with prompts for user inputs, followed by calculations of total and average, and finally displays the report card. It adheres to the sequential structure, ensuring a clear and logical flow aligned with the requirements.

Subsequently, the flowchart in Raptor visually maps the algorithm, illustrating decision points, input/output operations, and sequential processing. The Raptor tool facilitates evaluating the accuracy and efficiency of the algorithm by simulating the flow of execution and verifying that all functional and constraints are met.

In conclusion, the structured approach combining IPO analysis, pseudocode, and flowchart design effectively addresses the problem requirements. This methodology ensures a robust, understandable, and maintainable program capable of calculating and presenting student grades accurately, paving the way for future enhancements such as handling multiple students or incorporating additional assignment types.
