Chapter 4: Algorithms and Programming

Meaningful variable names

________ help with the readability of program code and reduce the level of complexity of a program.

input parameter

The ________ for the DISPLAY abstraction is expression.

modulus

A(n) ________ is a mathematical operation that returns the remainder after an initial number (the dividend) is divided by another number (the divisor)

dividend

If the ________ is less than the divisor, the resulting modulus calculation will equal the value of the ________.

modulus calculation

If the divisor is a multiple of the dividend, it will divide evenly with no remainder, resulting in a(n) ________ of 0.

abstraction

A(n) ________ is a way to represent essential features without including the background details or explanations.

DISPLAY

________ (expression) is an abstraction that is used on your AP exam to ________ a value of expression followed by a space.

assignment operator

The ________ allows a program to change the value represented by a variable.

left of MOD

A zero to the ________ is feasible and results in a modulus calculation of 0.

COBOL

The first language to use abstractions instead of machine language was ________, which was designed by Grace Hopper.

SWAP

THE ________: A common algorithm is the ________.

dividend

The ________ is 4, and 3 is the divisor.

modulus

The ________ is the integer remainder when two numbers are divided.

Abstractions

________ reduce complexity and allow for efficient design and implementation of complex software systems.

Coding in a programming language is often translated into code in another low

level language that the computer can execute

First

Parentheses

Second

MOD, *, /

Third

+, −

THE SWAP

A common algorithm is the swap

abstraction

is a way to represent essential features without including the background details or explanations.

*System.out.print(“Hello World”);*

\n

In JAVA, the same code can be written using the System.out.print abstraction:

Programmers

have worked to hide details by using abstractions.

Variables

vary

Coding

in a programming language is often translated into code in another low- level language that the computer can execute.

DISPLAY

(expression) is an abstraction that is used on your AP exam to display a value of expression followed by a space.

modulus

is a mathematical operation that returns the remainder after an initial number (the dividend) is divided by another number (the divisor).

list

is an ordered sequence of elements starting with the index 1.

ROTATE_RIGHT

will rotate the robot 90 degrees clockwise.

ROTATE_LEFT

will rotate the robot 90 degrees counterclockwise.

Loops

will repeat a section of code until a condition is met.

Swap

common algorithm

linear search

(or sequential search) is an algorithm for finding an element in a list.

binary search

is a search algorithm that halves the number of elements that need to be searched after every comparison.
