What is the difference between a flowchart and pseudocode?
A flowchart is diagramatic whilst pseudocode is written in a programming language (eg. Pascal, Java, Visual Basic).
A flowchart is textual whilst pseudocode is diagrammatic.
A flowchart is a diagrammatic description of an algorithm whilst pseudocode is a textual description of an algorithm.
Fowchart and pseudocode are representations of algorithms.
Which of the following assignment statements is assigning text to a variable?
myName = "Sir Philip"
myAge = 24
myTax = salary * .20
myGWA = 1.76
An identifier is the 'name' given to a variable.
For example:
distanceToSchool = 5 & " km"
What is the value of the variable?
5
5 km
5km
distanceToSchool
What structure is depicted in this flowchart?
