Analyze Design And Document A Simple Program Using Good Design
Your final project will be to analyze, design, and document a simple program that utilizes a good design process and incorporates sequential, selection, and repetitive programming statements as well as at least one function call and the use of at least one array. The specific problem you need to solve is: design a program that allows a user to input a list of family members along with their age and state where they reside, determine and print the average age of the family, and print the names of anyone who lives in Texas. You should include a program description, an analysis, test plan with data and expected output, pseudocode, and properly document all components. The design should accommodate at least 50 family members, with test cases including at least 5 members each, and should demonstrate separation of functionalities into functions or modules. Additionally, include clear variable definitions, formulas, sample calculations, and reasoning behind the choice of programming statements and data types.
Paper For Above instruction
The task of designing a program to analyze family data has several critical steps, involving careful planning of input collection, data processing, and output presentation. This project emphasizes the importance of applying structured programming principles, including the use of control structures, functions, arrays, and proper data management, to ensure the program is efficient, scalable, and easy to maintain.
Program Description: The main aim of this program is to enable a user to input details of family members—namely their names, ages, and states of residence—then compute the average age and identify members residing in Texas. The program should support entering data for up to 50 family members, with at least 5 members required per test case. It will utilize a combination of selection statements (if-else) to identify Texas residents, loops (for or while) to handle repetitive input procedures, and functions for modular design.
Analysis:
Input and Output:
The input consists of multiple entries, each including a name (string), age (integer or float), and state (string). The process continues until the user indicates completion, e.g., by entering a sentinel value like 'done'. The output includes the computed average age and a list of names of family members who live in Texas.
Variable Names and Definitions:
- `names[]` (array of strings): stores family members’ names
- `ages[]` (array of floats): stores their ages
- `states[]` (array of strings): stores their states of residence
- `totalAge` (float): sum of all ages for average computation
- `count` (integer): total number of family members entered
- `texasMembers[]` (array of strings): stores names of Texas residents
Formulas and Sample Calculation:
Average age = Total sum of ages / number of family members. For example, if ages are 82, 75, 45, 47, and 9, total sum = 258, and count = 5, so average = 258/5 = 51.6.
Functions and Arrays:
- `inputFamilyMembers()`: collects data for family members, populates arrays, ends on sentinel.
- `calculateAverageAge()`: computes and returns the average age.
- `listTexasResidents()`: identifies and outputs names of Texas residents.
Arrays will be used to store multi-member data efficiently, allowing iteration and processing within functions.
Programming Statements:
A combination of sequential statements for data input, selection (if-else) to filter Texas residents, and loops to process arrays. Control structures enable modular and readable code, while functions promote code reuse and separation of concerns.
Test Plan
| Test Data Set | Input | Expected Output |
|---|---|---|
| Test Case 1 |
Fred, Age: 82, State: MD Mary, Age: 75, State: OH Joe, Age: 45, State: TX Julie, Age: 47, State: TX Beth, Age: 9, State: TX |
Average Age: 51.6 Members who live in TX: Joe, Julie, Beth |
| Test Case 2 |
Anna, Age: 30, State: TX Paul, Age: 40, State: FL Emily, Age: 25, State: TX Mark, Age: 35, State: NY Sophie, Age: 28, State: TX |
Average Age: 31.6 Members who live in TX: Anna, Emily, Sophie |
| Test Case 3 |
John, Age: 55, State: CA Lisa, Age: 60, State: TX Mike, Age: 45, State: TX Sarah, Age: 50, State: FL Daniel, Age: 52, State: TX |
Average Age: 52.4 Members who live in TX: Lisa, Mike, Daniel |
Pseudocode
BEGIN
DECLARE arrays names[50], ages[50], states[50]
DECLARE variables totalAge = 0.0, count = 0, index = 0
DECLARE boolean inputComplete = FALSE
CALL inputFamilyMembers(names, ages, states, count, inputComplete)
IF count > 0 THEN
SET averageAge = calculateAverageAge(ages, count)
CALL listTexasResidents(names, states, count)
DISPLAY "Average Age:", averageAge
ELSE
DISPLAY "No family data entered."
ENDIF
END
PROCEDURE inputFamilyMembers(names, ages, states, count, inputComplete)
WHILE NOT inputComplete AND count
PROMPT for name or 'done' to finish
IF input = 'done' THEN
SET inputComplete = TRUE
ELSE
STORE name in names[count]
PROMPT for age
STORE age in ages[count]
PROMPT for state
STORE state in states[count]
totalAge += age
count += 1
ENDIF
ENDWHILE
END
FUNCTION calculateAverageAge(ages, count)
total = sum of ages[0 to count-1]
RETURN total / count
END
PROCEDURE listTexasResidents(names, states, count)
FOR i from 0 to count-1
IF states[i] == "TX" THEN
DISPLAY names[i]
ENDIF
ENDFOR

This design ensures modularity, scalability, and clarity, adhering to structured programming principles and accommodating user requirements effectively.
