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 be placed inside the static void Main(string args[])

Setup

dotnet new sdg-console -o VariablesCS

Additional Resources

• SDG Quick Reference on Strings
• SDG Quick Reference on Numbers
• Turning in Assignments
• Types and variables

Reading Material

• Microsoft intro to C#

Explorer Mode

• 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) called 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
  • Add some logic to your program that prints a different, special, greeting to the user if their name happens to be Alice.
• Using DateTime
  • Use the type DateTime to represent the date variables.
  • See the lesson on variables for some guidance on DateTime

Epic Mode

• Move all of your code to a separate method (but keep it in the same file) and invoke it from the Main method.
