Intro to Algorithm

What are the three algorithm constructions?

• Input, Output, Process

• Input/Output, Decision, Repeat

• Sequence, Selection, Repeat

• Loop, Input/Output, Process

What is an algorithm?

• flowchart

• flowchart or pseudocode

• step by step instructions used to solve a problem

• decision

When can we use algorithms?

• At any time to design solutions to problems

• Only with computers

• Only when programming

• Only when we want to put our flowchart in place.

When an algorithm is written in a programming language, it becomes a

• flowchart

• program

• pseudo-code

• Syntax

What should be considered when designing an algorithm?

• All the answers are true

• If the hardware is used correctly

• If the software is used correctly

• If there is more than one way to solve the problem

What is the difference between a flowchart and a pseudocode?

• A flowchart is a diagram while the pseudocode is written in a

  programming language (e.g. Pascal or Java)

• A flowchart is textual but the pseudocode is a diagram

• A flowchart and a pseudocode are the same

• A flowchart is a schematic description of an algorithm, while

  pseudocode is a textual description of an algorithm.

What is a Flowchart?

• A way to design a text-based algorithm

• A specific programming language

• A diagram that represents a set of instructions

• A scheme of instructions

In a flowchart, an input or output instruction is represented by _____?

• diamond

• Rectangle

• Parallelogram

• A circle

In a flowchart, a calculation (process) is represented by _____?

• A diamond

• Rectangle

• Parallelogram

• A circle

If ....... then ....... else ....... End If check ____?

• Only one condition

• Two conditions

• Three conditions

• Multiple conditions
