Computer Flowcharting Quiz

What is flowcharting?

• A written description of a process or algorithm?

• A type of mathematical equation?

• A tool used for data analysis?

• A visual representation of a process or algorithm using symbols and arrows?

Answer explanation

Flowcharting is not a written description, mathematical equation, or data analysis tool. Instead, it is a methodology used to depict a process or algorithm visually. It employs various symbols and arrows to represent different stages and the directional flow of the process, thus making the correct answer 'A visual representation of a process or algorithm using symbols and arrows'.

Can you spot the odd one out? Which of these is NOT a symbol used in flowcharting?

• D

• B

• C

• A

Answer explanation

In the context of flowcharting, symbols like 'D', 'B', and 'C' are often used to denote specific operations. The answer 'A' does not correlate to any known symbol in flowcharting, thus making it the odd one out in this question.

What does a rectangle symbol represent in a flowchart?

• Is it a code for input or output?

• Is it a sign for start or end point?

• Is it a symbol for decision or condition?

• Is it a representation for process or action?

Answer explanation

In a flowchart, different symbols represent different types of operations. A rectangle symbol specifically denotes a process or an action. Thus, the answer to the question 'What does a rectangle symbol represent in a flowchart?' is 'It is a representation for process or action'.

In flowcharts, what does a diamond symbol represent?

• The starting point

• The end point

• A looping path

• A decision point based on a condition

Answer explanation

In flowcharts, various symbols have distinct meanings. A diamond symbol, contrary to representing the start or end point or a loop, is used to represent a decision point. This symbol indicates a point in the process where a condition is tested, and the flow of control is directed depending on the result.

Which symbol represents an if-then statement in flowcharting?

• A triangle

• A diamond

• A square

• A circle

Answer explanation

In flowcharting, different symbols are used to depict different types of actions or steps. A diamond symbol is used to represent a decision point, which involves an if-then statement. So, the correct option is 'A diamond', which was the provided answer.

What is the purpose of decision making in flowcharting?

(a)  

• To create a colorful map of your decision-making journey?

• To predict the outcome of your decisions?

• To simplify work by breaking down decisions into steps?

• To mark a crossroad where a decision needs to be m

Answer explanation

The purpose of decision making in flowcharting, as per the correct answer, is to mark a crossroad where a decision needs to be made based on specific conditions. This means that decision-making in flowcharts helps to visually represent the decision points in a process or system.

What shape represents the input and output symbols in a flowchart; it also represents data in general.

•

Which statement depicts an if-then condition in a flowchart?

• A loop

• An output

• An input

• A decision

Answer explanation

In a flowchart, an if-then condition is represented by a decision. This is the option that best fits the context of the question. A decision in a flowchart is a point where the flow can branch based on a condition, similar to an if-then scenario in programming.

What is the correct syntax for an if-then statement in flowcharting?

• A circle-shaped box with 'if' inside it.

• A square-shaped box with 'if' inside it.

• A triangle-shaped box with 'if' inside it.

• A diamond-shaped box with 'if' inside it.

Answer explanation

In flowcharting, the correct syntax for an if-then statement is represented by a diamond-shaped box with 'if' inside it. Other shapes like circle, square, or triangle are not conventionally used for this purpose. So, the correct choice is a diamond-shaped box.

As a robot in a maze, what would you use an if-then statement for?

• To shout 'Hello World!'

• To solve math riddles

• To repeat dance moves

• To choose a path based on conditions

Answer explanation

The question asks about the application of an if-then statement for a robot navigating a maze. The correct choice is 'To choose a path based on conditions'. If-then statements in programming are used to make decisions based on certain conditions. In the context of a robot in a maze, these statements would be used to decide which path to take depending on certain conditions like the path's accessibility.
