L.O: STUDENTS WILL LEARN TO READ AND CREATE ALGORITHM
FLOWCHARTS.
There are no set rules for writing pseudocode, but you will often see the following:
• INPUT – indicates a user will be inputting something• OUTPUT – indicates that an output will appear on the screen• WHILE – a loop (iteration that has a condition at the
beginning)• FOR – a counting loop (iteration)• REPEAT – UNTIL – a loop (iteration) that has a condition at
the end• IF – THEN – ELSE – a decision (selection) in which a choice is
made• any instructions that occur inside a selection or iteration are
usually indented
A flowchart is a type a diagram that uses shapes and arrows to represent an algorithm.
Algorithms can be expressed in natural language or in pseudocode, text that describes the steps a program might carry out. These
languages for human understanding may help write the algorithm in a programming language.
Pseudocode:
Input: An integer Limit Ouput: Two integers: Number and Sum
1. Enter Limit 2. Set Number = 0. 3. Set Sum = 0. 4. Repeat the following: a. If Sum > Limit, terminate the repitition, otherwise. b. Increment Number by one. c. Add Number to Sum and set equal to Sum. 5. Print Number and Sum.
