Creating a Text to HTML Converter Class in C#

In this exercise, we will create a class TextToHTML that allows the user to enter multiple text strings and convert them into an HTML sequence. This class will facilitate the conversion of plain text into an HTML-like format by storing the strings and displaying them. The functionality of this class includes adding new text strings, displaying the current content, and converting the strings into a formatted HTML output.

Objective

1. Implement the TextToHTML class with an array to store the text strings.
2. Create the Add() method to allow adding strings to the array.
3. Implement the Display() method to output the array contents to the console.
4.Implement the ToString() method to return a concatenated string with newline characters.
5. In the Main function, test the methods by adding text, displaying the contents, and printing the result using ToString().

Create a class TextToHTML, which must be able to convert several texts entered by the user into a HTML sequence.

Example C# Exercise

 Copy C# Code 
using System;

class TextToHTML
{
    // Array to hold the text strings
    private string[] texts;
    private int count;

    // Constructor to initialize the array with a size of 10
    public TextToHTML()
    {
        texts = new string[10];
        count = 0;
    }

    // Method to add a new string to the array
    public void Add(string text)
    {
        // Check if there is space in the array to add a new string
        if (count < texts.Length)
        {
            texts[count] = text;
            count++;  // Increment the count after adding the text
        }
        else
        {
            Console.WriteLine("Array is full, cannot add more text.");
        }
    }

    // Method to display the contents of the array on the screen
    public void Display()
    {
        // Display all the texts added
        for (int i = 0; i < count; i++)
        {
            Console.WriteLine(texts[i]);
        }
    }

    // Method to return all the texts as a single string, separated by newline characters
    public override string ToString()
    {
        string result = "";
        // Concatenate all the texts, adding a newline between them
        for (int i = 0; i < count; i++)
        {
            result += texts[i] + "\n";
        }
        return result;
    }
}

class Program
{
    static void Main()
    {
        // Create an instance of TextToHTML
        TextToHTML textToHTML = new TextToHTML();
        
        // Add texts to the TextToHTML instance
        textToHTML.Add("Hola");
        textToHTML.Add("Soy yo");
        textToHTML.Add("Ya he terminado");

        // Display the contents on the screen
        Console.WriteLine("Displaying Texts:");
        textToHTML.Display();

        // Display the concatenated string with newline characters using ToString()
        Console.WriteLine("\nText as a single string:");
        Console.WriteLine(textToHTML.ToString());
    }
}

 Output

Displaying Texts:
Hola
Soy yo
Ya he terminado

Text as a single string:
Hola
Soy yo
Ya he terminado
