You Own A Consulting Firm And A Client Has Engaged You To Write a Cons

You own a consulting firm and a client has engaged you to write a console program. In general, this program must prompt the user for ten numbers, ranging between 10 and 100. The program compares the number entered to the previous number. In the event that it is a duplicate number, the user will be prompted to enter a different number. Display the number to the screen as long as it is not a duplicate.

For this assignment, complete the following: Write a console application that requests 10 numbers from the user as individual inputs. Each number must be between 10 and 100, inclusive. Compare each new number to the last one entered to determine if it is a duplicate. If it is, ask the user for a different number. Output each number to the screen once you have determined that all conditions are met. Submit your zipped Visual Studio project. In addition, prepare and submit a Word document that discusses any challenges you encountered including compilation errors, logic errors, or runtime errors that you had to resolve. The Word document should include your pseudocode and screenshots illustrating the successful execution of your program.

Developing a Console Program for Unique Number Input between 10 and 100

Creating a console application that prompts users to input ten numbers within a specified range and compares each input to the previous one is an engaging programming task. This task emphasizes the importance of input validation, control flow, and user interaction, which are fundamental in developing robust applications. Throughout this process, several challenges may arise, including handling incorrect inputs, managing duplicate entries, and ensuring the program adheres to the specified constraints. This essay explores the critical steps involved in designing this program, discusses common issues encountered during development, and provides solutions based on best programming practices.

Introduction

The primary goal of this project is to develop a console-based application that interacts with the user to receive ten numbers, each between 10 and 100. The application must compare each new input with the last entered number and disallow duplicates, prompting for a different number if necessary. The program ensures data integrity through input validation and enhances user experience by providing clear prompts and feedback. This task involves implementing a repetitive input collection loop, exception handling for invalid entries, and condition checks for duplicates and range adherence.

Design and Implementation Strategy

Implementing this program involves several key components:

• Input Validation: Ensuring that each number entered falls within the range of 10 to 100. If an invalid input is detected, the program prompts the user again until valid input is received.
• Duplicate Detection: Comparing each newly entered number with the last valid number to determine if it is a duplicate. If it is, the user is prompted to enter a different number.
• Control Loop: Using a loop to repeat input collection until ten valid, non-duplicate numbers are obtained.
• Output: Once a valid number is accepted, displaying it immediately to the user, maintaining transparency and feedback.

Challenges and Solutions

Handling Invalid Inputs

One of the most common challenges is managing invalid inputs such as non-numeric entries or numbers outside the acceptable range. To resolve this, exception handling techniques are employed. Using try-catch blocks in C# allows the program to catch errors when attempting to parse user input into an integer. If an exception occurs, the program prompts the user again without crashing, ensuring smooth operation.

Preventing Duplicates

Detecting duplicates involves comparing each new input to the previous input. A variable tracks the last valid number entered. If the new input matches this value, the system prompts for another entry. This comparison is straightforward but requires careful updating of the last input value after each successful entry.

Maintaining Range Constraints

To ensure each number falls within the specified range, input validation checks are added immediately after input parsing. If the number is outside the range, the program prompts the user again until valid input is provided.

Sample Pseudocode

Initialize counter to 0
Initialize lastNumber to null
While counter 
Prompt user for input
Read input as string
Try to convert input to integer
If conversion fails, display error and continue
If integer is outside 10-100
Display error and continue
If lastNumber is not null and input equals lastNumber
Display duplicate error and continue
Display input
Set lastNumber to input
Increment counter

Sample C# Implementation

The following C# code embodies the pseudocode logic:

using System;
namespace UniqueNumberInput
{
class Program
{
static void Main(string[] args)
{
int count = 0;
int? lastNumber = null;
while (count 
{
Console.Write($"Enter number {count + 1} (between 10 and 100): ");
string userInput = Console.ReadLine();
int number;
if (!int.TryParse(userInput, out number))
{
Console.WriteLine("Invalid input. Please enter a numeric value.");
continue;
}
if (number  100)
{
Console.WriteLine("Number out of range. Please enter a number between 10 and 100.");
continue;
}
if (lastNumber.HasValue && number == lastNumber.Value)
{
Console.WriteLine("Duplicate number detected. Please enter a different number.");
continue;
}
Console.WriteLine($"Number accepted: {number}");
lastNumber = number;
count++;
}
}
}
}

Conclusion

This exercise emphasizes critical programming concepts like input validation, control flow, and user interaction handling, which are vital for creating reliable applications. Managing exceptions ensures robustness against user errors, while duplicate detection maintains data integrity. Developing this program fosters skills in designing user-friendly console applications and encourages meticulous handling of edge cases. Challenges such as invalid inputs and duplication are common but manageable through systematic validation and control structures, leading to an efficient and resilient implementation.
