Pseudocode and Flowchart - Selection

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 flowchart and pseudocode are the same thing

What is the purpose of this symbol in creating program flowcharts?

• It evaluates a condition to determine the which action to take.

• It signals the beginning and the end of the program.

• It connects symbols and directs the flow of data in the program.

• It is used in accepting inputs or generating outputs in the program
