C++ Programming Quiz 1

2.

An algorithm is

The inputs and outputs of a program
The part of the computer that does the processing
A finite set of steps to solve a problem
A complete computer program

Correct Answer

A. A finite set of steps to solve a problem

Explanation

The correct answer is "A finite set of steps to solve a problem." An algorithm is a step-by-step procedure or a set of instructions that outlines how to solve a specific problem or complete a specific task. It is a systematic approach to problem-solving that provides a clear and logical sequence of actions to achieve the desired outcome. Algorithms can be implemented in various programming languages to create computer programs, but they are not the same as a complete computer program, which typically includes additional components such as input/output handling, user interfaces, and error handling.

A memory address is

Where a variable is stored
Where the computer is located
A step in the program.
Where the CPU is stored.

Correct Answer

A. Where a variable is stored

Explanation

A memory address refers to the specific location in the computer's memory where a variable is stored. It is a unique identifier that allows the computer to access and retrieve the value of the variable when needed. The memory address is crucial for the efficient functioning of a program as it enables the computer to manage and manipulate data effectively.

Which of the following is not part of the Software Life Cycle?

Analysis
Design
Data Entry
Implementation
Testing

Correct Answer

A. Data Entry

Explanation

Data Entry is not part of the Software Life Cycle because it refers to the process of inputting data into a computer system, which is not a specific phase or activity in the software development process. The Software Life Cycle typically includes phases such as Analysis, Design, Implementation, and Testing, which are essential steps in developing and delivering software. Data Entry, on the other hand, is a separate task that may be required during the operation or usage of a software system, but it is not directly related to the software development life cycle.

C++ statements end with a

Period
Comma
Semicolon
Nothing

Correct Answer

A. Semicolon

Explanation

C++ statements end with a semicolon. In C++, the semicolon is used to mark the end of a statement. It is a punctuation mark that indicates to the compiler that the statement has been completed. Omitting the semicolon at the end of a statement will result in a compilation error. Therefore, to ensure proper syntax and compilation of C++ code, it is necessary to end statements with a semicolon.

Which of the following is not an example of a program bug?

Run-time error
Operator error
Syntax error
Logic error

Correct Answer

A. Operator error

Explanation

An operator error is not an example of a program bug because it is a mistake made by the user while interacting with the program, rather than a flaw or mistake within the program's code itself. Program bugs refer to errors or flaws in the code that cause unintended or incorrect behavior, whereas operator errors occur when the user inputs incorrect or inappropriate data or commands.

The output of the compiler is called

The program
Source code
Linked code
Object code

Correct Answer

A. Object code

Explanation

Object code refers to the output of a compiler after it has translated the source code into a form that can be executed by a computer. It consists of machine code instructions that can be directly executed by the computer's processor. Object code is typically in binary form and is specific to the target hardware and operating system. It is the final step in the compilation process before the program can be run.

A finite sequence of precise instructions that leads to a problem solution is

A program
The CPU
A List of Inputs and Outputs
An Algorithm

Correct Answer

A. An Algorithm

Explanation

An algorithm is a finite sequence of precise instructions that leads to a problem solution. It is a step-by-step procedure that can be followed to solve a specific problem. Algorithms can be implemented in various ways, such as through programming languages, but the concept of an algorithm is independent of any specific programming language or computer hardware. Therefore, an algorithm is the correct answer in this context.

Int number;

Is an output statement
Is an input statement
Is a variable declaration
Is a program

Correct Answer

A. Is a variable declaration

Explanation

The given statement "int number;" is a variable declaration. In programming, the "int" keyword is used to declare a variable of integer type, and "number" is the name given to the variable. This statement is not an output or input statement, as it does not involve any data being displayed or accepted. It is also not a complete program, as it is just a single line of code.

Cout << “How many items would you want?\n”;

Is an output statement
Is an input statement

12.

Cin >> number;

Is an output statement
Is an input statement
Is a variable declaration
Is a program

Correct Answer

A. Is an input statement

Explanation

The given statement "cin >> number;" is an input statement. It is used to take input from the user and store it in the variable "number". The "cin" is an object of the input stream class, and the ">>" operator is used to extract the input from the user and assign it to the variable. Therefore, this statement is used for input operations in a program.

Rate this question:

13.

#include <iostream>

Is a variable declaration
An executable statement
An include directive
Illegal code

Correct Answer

A. An include directive

Explanation

The given correct answer is "an include directive". In C++, the "#include " statement is used to include the iostream library, which allows the program to use input and output streams. It is not a variable declaration or an executable statement, but rather a directive that tells the compiler to include a specific library. Therefore, the correct answer is an include directive.

C++ is an example of a

Machine language
High-level language
Low-level language
Assembly language

Correct Answer

A. High-level language

Explanation

C++ is considered a high-level language because it provides a level of abstraction from the underlying hardware and allows programmers to write code that is closer to human language. It includes features like object-oriented programming, dynamic memory allocation, and a rich library that makes it easier to develop complex applications. High-level languages are designed to be user-friendly and focus on readability and ease of use, making them more accessible to programmers compared to low-level languages like machine language or assembly language.
