Creating Algorithms through Pseudocodes and Flowcharts

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 connects the the part of a flowchart to another part of the flowchart located at a different page.

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

An algorithm illustrates:

• some steps in no particular order, and following no logical reasoning.

• a series steps in a particular order, following logical reasoning.

• some random shapes in a flowchart but in a set of order.

• a series of decisions needed to bake a cake.

When can algorithms be used?

• Only with computers

• Only with flowcharts

• Only when programming

• Any time to design solutions to problems

Refer to the given flowchart:

What is the output of the program?

• 3

• 4

• num3

• 0.714

• Error

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

• It connects the the part of a flowchart to another part of the flowchart located on the same page.

• It connects the the part of a flowchart to another part of the flowchart located at a different page.

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

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

Which of the following assignment statements is assigning text to a variable?

• myName = "Sir Philip"

• myAge = 24

• myTax = salary * .20

• myGWA = 1.76

If you are ask by your teacher to create a flowchart to find all the factors of a composite number given by the user, what are the most efficient structures will you use?

• sequence and selection

• selection and loop

• nested loops

• case and loop

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

• It declares the variables used in the program.

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

• It evaluates arithmetic operations.

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

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.
