Activity 2 - Basic arithmetic

• Displays the result of the sum of two numbers

Activity 3 - Flow control using if..else

• a. Display a message based on the value of a boolean variable
• b. Display ">5", "<5", or "=5" based on the value of a variable

Activity 4 - Decision making with match

• a. Display "it's true" or "it's false" based on the value of a variable
• b. Display "one", "two", "three", or "other" based on whether the value of a variable is 1, 2, 3, or some other number, respectively

Activity 5 - Basic arithmetic

Activity 8 - Organizing similar data using structs

• Print the flavor of a drink and it's fluid ounces

Activity 9 - Data management using tuples

• Print whether the y-value of a cartesian coordinate is greater than 5, less than 5, or equal to 5

Activity 10 - Working with expressions

• Print "its big" if a variable is > 100
• Print "its small" if a variable is <= 100

Activity 11 - Ownership

• Print out the quantity and id number of a grocery item

Activity 12 - Implementing functionality with the impl keyword

• Print the characteristics of a shipping box Must include dimensions, weight, and color

Activity 13 - Vectors

• Print 10, 20, "thirty", and 40 in a loop Print the total number of elements in a vector

Activity 14 - Strings

• Print out the name and favorite colors of people aged 10 and under

Activity 15 - Advanced match

• Print out a list of tickets and their information for an event
• Tickets can be Backstage, Vip, and Standard

• All tickets include the price

Activity 16 - Option

• Print out the details of a student's locker assignment
• Lockers use numbers and are optional for students

Activity 17 - Browsing standard library documentation

• Print a string in lowercase and uppercase

Activity 18 - Result & the question mark operator

• a.
  • Determine if a customer is able to make a restricted purchase
  • Restricted purchases require that the age of the customer is at least 21
• b.
  • Determine if an employee can access a building using a digital keycard
  • Employees that can access the building are:
    • Maintenance crews
    • Marketing department employees
    • Managers
  • Other employees that work at the company are:
    • Line supervisors
    • Kitchen staff
    • Assembly technicians
  • Ensure that terminated employees cannot access the building regardless of their position

Activity 19 - HashMap

• Print the name and number of items in stock for a furniture store
• If the number of items is 0, print "out of stock" instead of 0
• The store has:
  • 5 Chairs
  • 3 Beds
  • 2 Tables
  • 0 Couches
• Print the total number of items in stock

Activity 20 - User input

• Verify user input against pre-defined keywords
• The keywords represent possible power options for a computer:
  • Off
  • Sleep
  • Reboot
  • Shutdown
  • Hibernate
• If the user enters one of the keywords, a message should be printed to the console indicating which action will be taken
  • Example: If the user types in "shutdown" a message should display such as "shutting down"
• If the keyword entered does not exist, an appropriate error message should be displayed

Activity 21 - Map combinator

• Given a user name, create and print out a User struct if the user exists

Activity 22 - Testing

• Write tests for the existing program to ensure proper functionality

Activity 23 - Option combinators

• Use combinators as described in the functions: part_1, part_2, and part_3

Activity 24 - Iterator

• Triple the value of each item in a vector.
• Filter the data to only include values > 10.
• Print out each element using a for loop.

Activity 25 - Traits

• Calculate the perimeter of a square and triangle
  • The perimeter of a square is the length of any side*4.
  • The perimeter of a triangle is a+b+c where each variable represents the length of a side.
• Print out the perimeter of the shapes

Activity 26 - Modules

• a. External crates
  • Display the current date and time
• b. Inline Modules
  • The existing program is complete, but all the code exists in a single module. This code can benefit from being organized into multiple modules.
• c. External Modules
  • The existing program is complete, but all the code exists in a single module. This code can benefit from being organized into multiple external modules.

Activity 29 - Generics & Functions

• Create a function that accepts the Priority trait as a generic parameter
  • The function should print out the guest and their priority
• Use the function with at least two different guests

Project 1 - Interactive bill manager

• Create a command line bills/expenses manager that runs interactively. This mini project brings together many of the concepts learn thus far into a single application.
• The user stories/requirements are split into stages. Fully implement each stage as a complete working program before making changes for the next stage. Leverage the compiler by using cargo check --bin p1 when changing between stages to help identify adjustments that need to be made.
