Higher SDD - Count occurrences

​

Aims  

We are learning how to implement a count occurrence algorithm which traverse arrays or arrays of records.  

  

Achievements (theory)  

• I can write the code required to implement the standard algorithms in Python. Specifically, I can:  

• initialise and update variables  

• loop through an array/array of records with a fixed or conditional loop  

• set up a condition to test a criteria  

• return the position of a given piece of data within and array/array of records  

• I can predict the how the values of variables will change during the execution of a standard algorithm  

  

Achievements (practical)  

• I can implement a count occurrence algorithm in Python.  

Match

Match the construct with the description below.

• Assignment

• Selection

• Fixed iteration

• Conditional iteration

Updates or initialises a variable

Performs an action when a condition is m

Repeats code a set number of times

Repeats code until a condition is met

• Updates or initialises a variable

• Performs an action when a condition is m

• Repeats code a set number of times

• Repeats code until a condition is met

Categorize

Options (20)

average = total/10

total = 0

count = count + 1

if age > 18:

Set result to num1 + num2

name = 'John'

if temperature < 30:

if status == 'active':

if grade >= 60:

if day == 'Monday':

for i in range(10):

repeat 5 times:

for counter in range (number):

while count <= 10:

while found == False:

Repeat ... Until found = True

while score <0 or score >100:

Repeat ... until found = Tru or end of list

for x in range (len(array)):

for each pupil in pupils_array do

Categorise the lines of code into the correct construct.

• Loop through the array

• If statement

• Update variables
