Formalize Software Training "Example Problems"

[ghost]

Need to take all the notepad++ example problems Bill wrote last year and "formalize" them for software training. These are example programs students should write to test specific skills. Ideally we should organize these by "skill tested" and put them in some timeline matching how training teaches new skills.

Some tasks:

• Get the user's name, and greet them (the type of a name is "string")
• Make a calculator that adds three numbers
• Write a quadratic formula solver
• 99 bottles of Mountain Dew on the wall
• Calculate the average air speed velocity of an unladen swallow
• Get five numbers from the user, and print the AVERAGE of them

Problem 1: Determine Perfect Numbers

• loop through 1 to 1,000,000,000
• determines which numbers are "perfect"
• print each perfect number to the user Perfect Number: sum of the multiples equals the numbers 1 + 2 + 3 = 6 1 + 2 + 4 + 7 + 14 = 28

Problem 2: Determine Happy Numbers

• loop through 1 to 1,000
• determines which numbers are "happy"
• print each happy number to the user Happy Number: sum of the squares of each digit stays at 1 (after max of 100 loops) 19: 1^2 + 9^2 = 82 8^2 + 2^2 = 68 6^2 + 8^2 = 100 1^2 + 0^2 + 0^2 = 1

Problem 3: Turtle Class Create a class for a Turtle then create three turtles print their info info for each turtle:

• name
• color
• weight
• age

print format: "[name] is a [color] turtle that weighs [weight] pounds and is [age] years old" "Frank is a blue turtle that weighs 50 pounds and is 15 years old"

Problem 4: Car Class create a class to store information about a car

• car color
• car owner
• is the car running
• current speed (private)
• current gear (private)

the class should be able to do the following thing

• increase the speed
• decrease the speed
• increase the gear (limit to 5th gear)
• decrease the gear (limit to 1st gear)
• star the car
• turn off the car
• change the owner
• print out all car information in single string

Array Exercise 3a

Write a program which takes eight numbers form the user, stores them in an array, then find and print any duplicate numbers

Array Exercise 3b

Write a program which stores these numbers: { 5, 9, -3, 100, 2, -80, 1000} then asks the user for an input until they enter one of the numbers in the list, or they fail three times

Array Exercise 4

Write a program which takes four numbers from the user, then prints those four numbers, then takes three more numbers from the user, store them as an array of seven numbers, then print that large set all at once

Array Exercise 5

Write a program which starts with the following array: { 3, 7, 10, -4, 1, 0, 8} then sorts them in decending order, and prints them

Class Exercise 1

create a class to describe a backpack, that stores the following info: color, number of pockets, padding yes or no, water bottle holder yes or no number of books inside, calculator inside yes or no, phone inside yes or no make sure you decide which are PUBLIC and which are PRIVATE add functions to access PRIVATE properties also add functions for adding / removing books, adding / removing phone make sure these functions guard against impossible cases (remove a book when none are in there)

Class Exercise 2

Create a class to describe a turtle, that stores the following info: name, color, age, weight, and speed add functions to create a new turtle (with a name and color), a function to make the turtle older (years older and pounds heavier), and a function that prints a description of the turtle (in a full sentence) speed should be calculated internally by the following function: Speed = (Age 10) - (Weight * 2) the turtle's speed should be calculated whenever it get's older

Guessing Game

Write a program which plays a guessing game with the user The program picks a random number and the user must guess it The goal is to guess the number in a few guesses as possilbe

The program should ask the user for a level setting: 1, 2, or 3 level 1 generates a random number between 1 and 10 level 2, between 1 and 100 level 3, between 1 and 1000 The program should print a final score once complete score is the the max number to guess, minus the number of guesses the user took to guess correctly *higher scores are better! The program should end (game over) if the user guesses 0

*create a class called "RandomNumber" which holds the number to guess this class should also have controls for the different levels
