Programming Principles Review

§What is an algorithm?

• A finite set of instructions that accomplish a specific task.

• The application of each step of an algorithm in the order in which the code statements are given.

• Determines which part of an algorithm are executed based on a condition being true or false.

• A repeating portion of an algorithm.

§What are the three types of programming constructs used in algorithm implementations?

• Sequencing,

• Selection

• Iteration

• Flowgorithm

§What is sequencing?

• The application of each step of an algorithm in the order in which the code statements are given.

• Determines which part of an algorithm are executed based on a condition being true or false.

• A repeating portion of an algorithm.

§What is selection?

• The application of each step of an algorithm in the order in which the code statements are given.

• Determines which part of an algorithm are executed based on a condition being true or false.

• A repeating portion of an algorithm.

§What is iteration?

• The application of each step of an algorithm in the order in which the code statements are given.

• Determines which part of an algorithm are executed based on a condition being true or false.

• A repeating portion of an algorithm.

§What is an event in coding?

• An occurrence associated with an action and supplies input data to a program.

• An abstraction inside a program that can hold a value.

• Affect the sequential flow of control by executing different statements based on the value of a Boolean expression.

• Projectiles destroy themselves when they go off the visible screen.

§What is a variable?

• An occurrence associated with an action and supplies input data to a program.

• An abstraction inside a program that can hold a value.

• Affect the sequential flow of control by executing different statements based on the value of a Boolean expression.

• Projectiles destroy themselves when they go off the visible screen.

§What are conditional statements?

• An occurrence associated with an action and supplies input data to a program.

• An abstraction inside a program that can hold a value.

• Affect the sequential flow of control by executing different statements based on the value of a Boolean expression.

• Projectiles destroy themselves when they go off the visible screen.
