CHAPTER 1: Introduction(Variables, Operators, escape sequence)

• Enter an input from user asking their age and name. Prompt the user to enter their name and age. Store the input in appropriate variables(string and int). Print a greeting that includes the entered name and age.
• Take three integer input from the user. These input are the scores they received in a test(out of 20). Print the total scores, average and names of the subjects in a single line using three different print statements. Hint: How do you stitch multiple prints?
• Take age from the user and save it in a variable. Print the number of years required for that user to reach the age of 50.
• Take two numbers from the user. Perform an operation involving two arithmetic operations. It can be any arithmetic operation.
• Ask the user to enter the length and width of a rectangle. Use float variables to handle potential decimal values. Calculate and print the area of the rectangle.

CHAPTER 2: CONDITIONS

1. Take length and breadth of a rectangle and check if it is a square or not.
2. Take age as user input from 3 users. Find the youngest and oldest among them.
3. Ask user for a year and find if it is a leap year or not.
4. Allow the user to enter a temperature value(between two values). Ask whether the value is in Celsius (C) or Fahrenheit (F). Use a char variable (unit) to store the user’s choice. Implement a if-else if chain for conversion based on the unit. Handle invalid unit input gracefully.Write a program to accept cost price of a car and display road tax to be paid according to following table.
   1. Price of the car and equivalent road tax to be paid on brand-new cars ​

      Price of the car	Road tax to be paid
      < $50,000	5%
      $50,000 – $99,999	10%
      $100,000 – 149,999	15%
      >150,000	20%

      Price of the car and equivalent road tax to be paid on brand-new cars
      
      
5. Hey! It’s that time of the year. Warm coffee, Gloomy weather, and filling taxes…..wait?WHAT!!
   In this exercise, you will not only learn to condition but also to calculate taxes.
   Imagine user being a single filer for 2023. The tax rate by IRS can be found here. In total, there are 7 tax brackets, we will deal with 5 of them as shown in table below.<br>
   * Take an input salary from the user.
   * Based on the salary, calculate the tax amount the user owns to the IRS.
   
   Use a series of if elif statements to achieve the result

   Salary	Tax
   < $11,000	10%
   $11,000 – $44,725	$1,100 + 12% of difference
   $44,725 – $95,375	$5,147 + 22% of the difference
   $95,375 – $182,100	$16,290 + 24% of the difference
   $182,100 – $231,250	$37,104 + 32% of the difference
