Software Applications Are Created To Solve Problems

Software Applications Are Created To Solve Problems That A Business Or

Software applications are created to solve problems that a business or even an individual might have. Planning is a crucial step in the software development process. Applications may not achieve the intended goal unless properly planned. Imagine that you are a programming consultant. One of your smaller clients’ needs your help writing a program.

Your client has an e-commerce Web site but wants to avoid being sued for allowing children to make purchases without the authorization of their parents. Prepare a document that guides your client in program preparation and includes an example console program. The console program must verify the age of a customer attempting to make an online purchase. The program must prompt the customer for his or her year of birth, and it will calculate whether the customer is over 18 years old. The program will then display a message to the customer that his or her purchase request is accepted or denied.

Your paper must include the following 5 parts in addition to the coded solution: · A problem analysis chart with each of the following sections: · Given information · Required results · Processing required to obtain the results · Solution alternatives · A flowchart showing the program processing flow · A chart showing input, output, and processing · An algorithm in pseudocode describing the steps the program will perform. This pseudocode algorithm would consist of a list of steps explaining the sequence of tasks the program will follow to complete the task. · The console program solution with a screenshot of the executed program.

Paper For Above instruction

The proliferation of e-commerce platforms has revolutionized how consumers access goods and services, but it also introduces regulatory challenges, especially in protecting minors from unauthorized purchases. To address these challenges, implementing an age verification mechanism is essential for online retailers. This paper provides a comprehensive guide for a client to develop a simple console-based age verification program, including problem analysis, process flowcharts, pseudocode, and a sample program with execution demonstration.

Problem Analysis Chart

Given Information

  • The customer will input their year of birth.
  • The current year is known or can be obtained programmatically.
  • The program needs to determine whether the customer is over 18 years old.

Required Results

  • The program calculates the customer's age based on the current year and their birth year.
  • The program displays a message indicating whether the purchase request is accepted (if over 18) or denied (if 18 or younger).

Processing Required to Obtain Results

  • Prompt the user for their year of birth.
  • Retrieve or set the current year.
  • Calculate age by subtracting the birth year from the current year.
  • Compare age to the threshold of 18 years.
  • Display appropriate message based on the comparison.

Solution Alternatives

  • Using different programming languages such as Python, Java, or C++.
  • Implementing graphical user interfaces instead of console-based prompts.
  • Adding additional input validation to ensure valid year entries.

Flowchart of Program Processing

Flowchart showing program processing flow

The flowchart begins with program start, prompts for birth year, retrieves current year, calculates age, compares age to 18, displays acceptance or denial message, and ends.

Input, Output, and Processing Chart

Input Processing Output
Year of birth Calculate age = Current Year - Birth Year Display "Purchase Accepted" or "Purchase Denied"

Pseudocode Algorithm

BEGIN


PROMPT user: "Enter your year of birth:"


READ birthYear


GET currentYear


SET age = currentYear - birthYear


IF age >= 18 THEN


DISPLAY "Your purchase request is accepted."


ELSE


DISPLAY "Your purchase request is denied."


ENDIF


END

Console Program Solution

Below is a sample implementation in Python demonstrating the age verification logic. It includes a test run with a screenshot showing the program's execution.

Python Age Verification Program


from datetime import datetime


def verify_age():


current_year = datetime.now().year


try:


birth_year_input = input("Please enter your year of birth: ")


birth_year = int(birth_year_input)


if birth_year > current_year or birth_year 

print("Invalid birth year. Please enter a valid year.")


return


age = current_year - birth_year


if age >= 18:


print("Your purchase request is accepted.")


else:


print("Your purchase request is denied.")


except ValueError:


print("Invalid input. Please enter a numerical year.")


if __name__ == "__main__":


verify_age()

Note: Upon running this program, a user inputs their birth year, and the program outputs whether the purchase is accepted or denied based on age.
