01 - 02 - Variables

[Tmoney2020]

Let's get started

Today, we are starting our journey into development. This journey has to start somewhere. For this assignment, you will be making a program that demonstrates some programming fundamentals.

Objectives

• Ensure your development environment is setup
• Practice creating variables
• Practice working with user input

Requirements

Make sure you have followed the setup instructions for your computer's operating system

Follow this guide to review how to create and run C# applications

All your code should place inside the static void Main(string args[])

Explorer Mode

• [x] Create a new app that does the following.

  • Practice Creating Variables

  • Create a variable (use your best judgment for type) that stores the numberOfCupsOfCoffee that you drink every day.

  • Create a variable (use your best judgment for type) called fullName and set it equal to your full name.

  • Create a variable (use your best judgment for type) call today and set it equal to today's date.

  • Use Console.WriteLine and your variables, numberOfCupsOfCoffee, fullName, and today, to output all three on one line.

  • Practice Getting Input From the User

  • Ask the user for their name and store it in a variable named userName.

  • Print out a greeting to the user, using their name.

  • Practice Getting Different Types of Input From the User

  • Ask the user to input two numbers.

  • Get the numbers as strings using Console.ReadLine, store them in variables named firstNumberAsString and secondNumberAsString

  • Converting String Input Into Numbers

  • Convert each string above to a double using Double.parse. Save the first value in a variable named firstOperand and the second value in a variable named secondOperand.

  • Doing Math

  • Add the operand variables from above and save the results in a variable named sum.

  • Subtract the secondOperand variable from the firstOperand variable and save the results in a variable named difference.

  • Multiply the operand variables and save the results in a variable named product.

  • Divide the firstOperand by the secondOperand and save the results in a variable named quotient.

  • Find the remainder when one operand is divided by the other and save the results in a variable named remainder. See this page if you need to learn more about the modulo operator.

  • Use Console.WriteLine to present the user, in a meaningful way, each of the values for the sum, difference, quotient, product, and remainder variables. (e.g. perhaps one of your outputs is similar to If you add 4 and 5 you get 9 if 4 and 5 were the input)

Adventure Mode

• Using Logic
  • [x] Add some logic to your program that prints a different, special, greeting to the user if their name happens to be Alice.
• Using Advanced Types
  • [x] Use the type DateTime to represent the data variables.

Epic Mode

• [ ] Move all of your code to separate file and invoke it from the Main method.

Additional Resources

• Types and variables

Reading Material

• Microsoft intro to C#
