CSP Test Unit 3

In the following code segment, score and penalty are initially positive integers. The code segment is intended to reduce the value of score by penalty. However, if doing so would cause score to be negative, score should be assigned the value 0.Which of the following changes can be made so that the code segment works as intended?

Considering the robot code below, which direction, if the robot is facing upward, will the front of the robot be facing after the code is complete?

Upward

Logic error

a mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly.

Run-time error

a mistake in the program that occurs during the execution of a program; programming languages define their own run-time errors.

Syntax error

a mistake in the program where the rules of the programming language are not followed.

Event handler

a part of code that 'handles' or listens for a specific type of event; when that event occurs, the code inside the event handler is run.

Iteration

a repeating portion of an algorithm; it repeats a specified number of times or until a given condition is met.

Overflow error

an error that occurs when a computer attempts to handle a number that is outside of the defined range of values.

Nested conditional statements

consist of conditional statements within conditional statements.

Selection

determines which part of an algorithm is executed based on a condition being true or fals

Pseudo-random numbers are generated from physical phenomena that take place outside of the computer.

false

The following code represents a Sequencing algorithm

false

The following code represents an Iteration algorithm

false

String concatenation

joins together two or more strings end-to-end to make a new string.

The three different constructs used in algorithms are:

sequencing, iteration, selection

Proper variable names (choose all the correct answers):

stateName personName, carModel

What is the substring text in the variable answerIs?

taking test

Sequencing

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