ALGORITHM A DAY- HOT!
Below are a list of excerices to help you create an algorithm for a problem. There are two types of algorithm
HOT! Algorithm A Day 1
Write an algorithm in pseudocode which: - asks the user to input 2 numbers - outputs the larger of the two numbers along with a suitable message [5 marks]
Please complete on paper or submit via Edmodo
HOT! Algorithm A Day 2
If Monday = 0, Tuesday = 1 etc…
…write an algorithm in pseudocode which:
- Asks the user to enter a number,
- Outputs the day that the number represents,
- Validates the number so that an error message displays if the number is not a valid weekday number. [5 marks]

HOT! Algorithm A Day 3
A program has been written to obtain 3 random virtual dice rolls:
DiceRoll(1) = Random Number 1-6
DiceRoll(2) = Random Number 1-6
DiceRoll(3) = Random Number 1-6
DISPLAY DiceRoll(1)
DISPLAY DiceRoll(2)
DISPLAY DiceRoll(3)
Rewrite this algorithm in pseudocode so that it makes use of iteration. [4 marks]

HOT! Algorithm A Day 4
A dog that is 5 years old is equivalent to a 42 year old human. You need to write a program that converts the age of a dog to the equivalent age of a human.
Write an algorithm in pseudocode which:
- Asks for the age of the dog in years
- If the age is 2 or less, the human equivalent is 12 times the age
- If the age is more than 2, the human equivalent is 24 for the first 2 years, plus 6 for every additional year. [5 marks]

HOT! Algorithm A Day 5
Consider the array numbers = [2, 5, 3, 6, 2, 3, 6, 4] where the value of numbers(2) is 3.
Write an algorithm in pseudocode which: - Adds up the numbers in the array - Displays the result. To get full marks a loop should be used in your algorithm.

HOT! Algorithm A Day 6
A taxi firm charges £3 for the first mile and £2 for every mile after that. If there are 5 or more passengers, an extra 50% is added to the price. Write an algorithm in pseudocode which calculates the cost of a journey.
The algorithm should:
- Ask the user to enter the number of passengers
- Ask the user to enter the distance (as an integer)
- Calculate the price of the journey
- Output the price on the screen [7 marks]

HOT! Algorithm A Day 7
In a factory, the wages earned by a worker is either £2 for every teddy bear they have made or £5 for every hour they have worked, whichever is higher.
Write an algorithm in pseudocode which:
- Allows the user to input the number of teddy bears made and the number of hours worked
- Calculates the wages for the number of teddy bears made
- Calculates the wages for the number of hours worked
- Outputs the larger of the two results. [6 marks]

HOT! Algorithm A Day 8
An isosceles triangle is one which has at least two equal length sides.
Write an algorithm in pseudocode which:
- Asks the user to enter the lengths of a triangle
- Works out if the triangle is isosceles
- Outputs a message stating whether the triangle is isosceles or not. [5 marks]

HOT! Algorithm A Day 9
A free drinks machine provides 20 different drinks.
The machine has a small keypad with keys 0-9, Submit and Cancel.
It has a small LCD display, which can display messages to the user.
To get a drink the user selects it by typing in the relevant number (1-20).
If they type in the wrong number, they can cancel and enter a new number.
When they are happy with their choice they press the submit button.
If the selection is valid (1-20) and the drink available, the machine will dispense the drink.
Write an algorithm in pseudocode which for the process outlined above [6 marks]

HOT! Algorithm A Day 11
A display board can show a flashing message of up to 20 characters.
*******WELCOME******
Write an algorithm in pseudocode which: - Allows the user to input the message and the number of flashes - Rejects the message if it is longer than 20 characters and stops - Otherwise it repeatedly displays the message and clears the display for the correct number of times. [5 marks]

HOT! Algorithm A Day 12- (OCR 20)
MyHotPizza company have developed a new loyalty reward system for customers. Customers are automatically sent a reward card if they order more than 20 pizzas in a year.
They have a log of customer’s orders stored in a file, as shown:
Customer Name Large Medium Small Card?
Smith, J 5 6 1 No
Williams, P 10 12 3 Yes
Write an algorithm (Pseudocode) that goes through the customer orders, and where needed, sends customers a loyalty card if they do not already have one. If they have not ordered enough pizzas, then it removes them from the card list.

HOT! Algorithm A Day 13- (OCR 21)
A local swimming centre offers the following discounts:
-
Members who are aged between 13 and 15 receive a 30% discount.
-
Members who are aged between 16 and 17 receive a 20% discount.
-
Members who are aged 50 and over receive a 40% discount.
-
All other members receive no discount.
Create an algorithm using Pseudocode for the above actions.

HOT! Algorithm A Day 14- (OCR 22)
Write an algorithm that:
-
Asks the user to input how many marks they got on a test.
-
It should then convert this to a grade between 1 to 9 using the table below and then output the grade to the user. If they have not scored enough to be given a grade than a ‘U’ grade must be output.
Mark Grade
Greater than or equal to 10 1
Greater than or equal to 20 2
Greater than or equal to 30 3
