Nat 5 Standard Algorithms + Predefined Functions

You are a writing a program to add up the total cost of all the items in a shopping cart. State the standard algorithm you should use?

• Running Total

• Traversing an array

• Input Validation

Identify which code below correctly defines an array of strings with a length of 15

• array = [15]

• array = [" "]

• array = [" "] * 15

• array = [" "] * 14

State which standard algorithm would you use if you had to get test scores from an array to check which grade they should receive.

• Running Total

• Input Validation

• Traversing an array

Given that you have to be 18 or over to enter a club, identify the conditional loop that would be in the input validation algorithm.

• For counter in range (0, 18)

• while age >=18

• while age > 18

• while age < 18

State which of the following pseudocode defines the standard algorithm for input validation?

• Get input, loop while the input is unacceptable, get user to reenter

• Get input, check if valid

• Get input, loop while the input is unacceptable, display error message, get user to reenter

• Loop while the input is unacceptable, get user to reenter

You want to use a running total algorithm to find out the total miles ran each day in a month. State the type of loop you would use.

• Fixed Loop

• Conditional Loop

Below is the code for a running total using an array complete the code:

array = [5, 4, 3, 2, 1]

total = 0

for counter in range (0, len(array)):

number = ?

total = number + total

• array

• array[0]

• array[counter]

• array [ 5, 4, 3, 2, 1]

State which of the following pieces of code will allow you to find out how many elements are in an array.

• size = size (array)

• size = length (array)

• size = Length

• size = len (array)

State the result from the following program:

number = 7.89321

number = round(number, 2)

print(number)

• 7.8932

• 7.89

• 7

State the correct method of creating a random number between 25 and 50 in Python.

• import random

  number = random.randint(25, 50)

• import rand

  number = random(0, 10)

• import random

  number = random.randint(0, 1) * 50

• import

  number = random.randint(0, 10)
