Algorithms and Programming

Which description best describes a syntax error?

• This type of error will produce an unexpected output but won’t stop the program running.

• This is a type of error that breaks the rules of the programming language and will not allow the program to run.

• The process of removing unnecessary details and including only the relevant details.

• This type of error will cause the program to crash while it’s running because of an illegal error.

What is a variable?

• A text-based alternative to representing algorithms and is simplified form of programming code.

• The process of breaking a complex problem down into smaller, more manageable parts.

• A value that does not change while the program is running and is assigned when the program is designed.

• A named memory location that holds data that can be changed.

Which description best matches the programming construct sequence?

• The process of following different pathways based upon a condition.

• This is the repetition of programming code a set number of times or until a certain result has been achieved.

• A value that does not change while the program is running and is assigned when the program is designed.

• The process of executing one instruction after another in order.

Which description best matches the programming construct iteration?

• A graphical method for representing the steps in an algorithm using a combination of symbols.

• The process of following different pathways based upon a condition.

• This is the repetition of programming code a set number of times or until a certain result has been achieved.

• The process of executing one instruction after another in order.

What is abstraction?

• The process of breaking a complex problem down into smaller, more manageable parts.

• A value that does not change while the program is running and is assigned when the program is designed.

• The process of removing unnecessary details and including only the relevant details.

• A named memory location that holds data that can be changed.

Which of these statements is describing pseudo code?

• Altering the behaviour of a variable from one data type to another (e.g. integer to a string).

• A text-based alternative to representing algorithms and is a simplified form of programming code.

• A graphical method for representing the steps in an algorithm using a combination of symbols.

• The process of breaking a complex problem down into smaller, more manageable parts.

Which description best matches the data type integer?

• A single alphanumeric character.

• A whole number, positive or negative and is only used for data that requires calculations.

• A sequence of characters used for all data that is not involved in calculations.

• Used to store a True or False statement within a variable.

Which description best matches the data type string?

• A single alphanumeric character.

• A whole number, positive or negative and is only used for data that requires calculations.

• A sequence of characters used for all data that is not involved in calculations.

• Used to store a True or False statement within a variable.

Which description best matches the data type boolean?

• A single alphanumeric character.

• A whole number, positive or negative and is only used for data that requires calculations.

• A sequence of characters used for all data that is not involved in calculations.

• Used to store a True or False statement within a variable.

What is casting?

• A value that does not change while the program is running and is assigned when the program is designed.

• This is the repetition of programming code a set number of times or until a certain result has been achieved.

• Altering the behaviour of a variable from one data type to another (e.g. integer to a string).

• Understandable by humans but must be compiled before being understood by the computer.
