Chapter 2: Problem 13

The following data 72 'A' "Hello World" 2.8712 are all examples of A) Variables B) Literals or constants C) Strings D) None of the above

Short Answer

Expert verified
Answer: B) Literals or constants

Step by step solution

01

Understand the terms

Let's first understand what each term means: A) Variables: These are named storage locations for data that can change during the execution of a program. B) Literals or constants: These are fixed values that cannot change during program execution. C) Strings: These are sequences of characters enclosed within single or double quotes. D) None of the above: This option indicates that none of the given terms apply to the data.
02

Analyze the data

Now, let's examine each piece of data in the exercise: 1. 72: This is a numerical value that represents an integer. 2. 'A': This is a single character enclosed in single quotes. 3. "Hello World": This is a sequence of characters enclosed within double quotes. 4. 2.8712: This is a numerical value that represents a floating-point number.
03

Compare the data to the terms

Comparing the provided data with the definitions of the terms: - None of the given data are named storage locations, so they cannot be variables. - The data consists of fixed values and sequences of characters, which fits the definitions of literals, constants, and strings.
04

Determine the correct answer

Based on our analysis, the correct answer is B) Literals or constants, as all the examples provided are fixed values that do not change during program execution.
