Mr. Exume flowchart 2

1. L.O: STUDENTS WILL
LEARN TO READ AND
CREATE ALGORITHM
FLOWCHARTS.

2. 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

3. A flowchart is a type a diagram that uses
shapes and arrows to represent an
algorithm.

33. 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.
