Task 1:

Task Description:

1. Scenario: You are tasked to simulate a simple shopping experience using conditional statements and loops at a supermarket.
2. Requirements:
   • Create a TypeScript program that simulates a shopping scenario with multiple conditions.
   • Utilize if-else, if-else if-else statements for decision making based on different scenarios encountered while shopping.
   • Incorporate nested loops to simulate actions within various sections of the supermarket.
3. Functionalities to Include:
   • Scenario 1 - Buying Groceries:
     • Simulate buying fruits, vegetables, and groceries.
     • Apply if-else statements to check specific conditions:
       • Check if the customer wants fruits or vegetables.
       • Based on the choice, suggest different items available and their prices.
       • Display the total bill.
   • Scenario 2 - Checking Discounts:
     • Introduce a discount scenario based on the total bill amount.
     • Use if-else if-else statements to apply discounts:
       • If the bill amount is above a certain value, apply a discount.
       • Display the discounted total.
   • Scenario 3 - Checkout Process:
     • Simulate the checkout process.
     • Use nested loops to ask for payment methods:
       • First, ask the user for the preferred payment method (nested loop for payment options).
       • Display a confirmation message based on the payment method chosen.

Task 2:

• Scenario 1: Sum numbers
  • Write a function named add that takes two numbers as arguments and returns their sum.
• Scenario 2: Check Even or Odd
  • Develop a function checkEvenOrOdd that checks if a given number is even or odd.
  • The function should take an integer as a parameter and return a string indicating whether the number is even or odd.
• Scenario 3: Calculate Area:
  • Create a function calculateArea that calculates the area of a rectangle.
  • The function should take width and height as parameters and return the calculated area.
• Scenario 4: String Reversal
  • Implement a function reverseString that reverses a given string.
  • The function should take a string as a parameter and return the reversed string.
• Scenario 5: Temperature Conversion:
  • Create a function convertCelsiusToFahrenheit that converts temperature from Celsius to Fahrenheit.
  • The function should take a temperature value in Celsius as a parameter and return the equivalent temperature in Fahrenheit.

Task 3:

• Scenario 1 - Modify Array with Methods:
  • Initialize an array with some initial elements.
  • Demonstrate the usage of the following array methods:
    • push: Add new elements to the end of the array.
    • pop: Remove the last element from the array.
    • shift: Remove the first element from the array.
    • unshift: Add new elements to the beginning of the array.
• Scenario 2 - Subarray Creation:
  • Implement the use of splice and slice to create subarrays from the original array:
    • splice: Create a subarray by removing elements from the original array.
    • slice: Create a subarray without modifying the original array.

Guidelines:

• Incorporate comments to explain the logic behind each condition, loop, function or array
• Test your program with various inputs to ensure it responds accurately to different scenarios.

Submission Guidelines:

• Submit the TypeScript file containing your program.
• Include a brief explanation of how your program works and any challenges faced during the implementation.
