ALGORITHMS, PSEUDOCODE & FLOWCHART

To repeat a task number of times we use 

• input statement
• conditional statement
• loop statement
• output statement

If ................then ....else ........endif  check

• one condition
• two conditions
• three condtions
• many conditions

Repeat .......................Until is a

• Positive loop
• Negative loop

What is an Algorithm?

• A flowchart
• Step by step instructions used to solve a problem
• A decision
• A Pseudocode

What are the three algorithm constructs? 

• Sequence, selection, repetition 
• Input, output, process 
• Input/output, decision, terminator    
• Loop, input/output, process    

What is the difference between a flowchart and pseudocode? 

• A flowchart is diagramatic whilst pseudocode is written in a programming language (eg. Pascal or Java) 
• A flowchart is textual but pseudocode is diagrammatic 
• A flowchart is a diagrammatic description of an algorithm whilst pseudocode is a textual description of an algorithm 
• A flwochart and pseudocode are the same thing 

In a flowchart a calculation (process) is represented by 

• A rectangle 
• A rhombus 
• A parallelogram 
• A circle 

A flowchart needs to represent the a situation where for each mark a student is award 'Pass' or 'Fail'...the system will consider the mark and if it's 50 or over award 'Pass', else it awards 'Fail'. This is an example of which of the algorithm constructs?                                    

• Decision 
• Loop 
• Sequence 
• All of the above 

What is a flowchart?

• A text-based way of designing an algorithm
• A specific programming language
• A diagram that represents a set of instructions
• A bullet point list of instructions

Programming languages give computers instructions

• True
• False
