BJC Unit 1: Introduction to Programming

reporter block

A ________ _____ is an oval-shaped block which reports a value.

composition

___________ is using the result from one reporter as the input to another reporter.

command blocks

_______ _____ tell the computer to do something without reporting a value. For example, say and broadcast.

debugging

_________ is the process of testing, finding problems, and fixing them.

function block

Block that Snap! calls a reporter, most languages call a ________. This is an oval-shaped block.

procedure block

Block that Snap! calls a command, most languages call a ________. This is a rectangular-shaped puzzle block.

procedure

The AP Exam uses this term for both reporters and commands.

condition

The if and if-else blocks are called ____________ because they control the code based on a condition.

selection

Deciding which part of an algorithm to run based on a condition is called a _________.

sequencing

__________ is the process of ordering code.

algorithm

An _________ is a sequence of steps that are usually performed by a computer.

abstraction

Using a block you've already written to help write another block is an example of ___________. It is arguably the most important idea in computer science.

iteration

The program structure computer scientists also describe as looping or repetition. Along with sequencing and selection, it is a building block of algorithms.
