Who was the programmer for Charles Babbage’s analytical engine?
- A.
Grace Hopper
- B.
Ada Lovelace
- C.
Lord Bryan
- D.
Walter Savitch
Correct Answer
B. Ada LovelaceExplanation
Ada Lovelace was the programmer for Charles Babbage's analytical engine. Ada Lovelace is often considered the world's first computer programmer, as she wrote the first algorithm designed to be processed by a machine. She worked closely with Charles Babbage and made significant contributions to the development of the analytical engine, including creating a plan for how the machine could calculate Bernoulli numbers. Lovelace's work laid the foundation for modern computer programming and her contributions are still celebrated today.Rate this question:

An algorithm is
- A.
The inputs and outputs of a program
- B.
The part of the computer that does the processing
- C.
A finite set of steps to solve a problem
- D.
A complete computer program
Correct Answer
C. A finite set of steps to solve a problemExplanation
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.Rate this question:

A memory address is
- A.
Where a variable is stored
- B.
Where the computer is located
- C.
A step in the program.
- D.
Where the CPU is stored.
Correct Answer
A. Where a variable is storedExplanation
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.Rate this question:

Which of the following is not part of the Software Life Cycle?
- A.
Analysis
- B.
Design
- C.
Data Entry
- D.
Implementation
- E.
Testing
Correct Answer
C. Data EntryExplanation
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.Rate this question:

What does the following line of code display to the screen? cout << “This is the computer\n programming book\n”;
- A.
This is the computer programming book
- B.
This is the computer
- C.
Nothing
- D.
This is the computer programming book
Correct Answer
D. This is the computer programming bookExplanation
The given line of code uses the cout object to display the string "This is the computer programming book" to the screen.Rate this question:

C++ statements end with a
- A.
Period
- B.
Comma
- C.
Semicolon
- D.
Nothing
Correct Answer
C. SemicolonExplanation
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.Rate this question:

Which of the following is not an example of a program bug?
- A.
Run-time error
- B.
Operator error
- C.
Syntax error
- D.
Logic error
Correct Answer
B. Operator errorExplanation
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.Rate this question:

The output of the compiler is called
- A.
The program
- B.
Source code
- C.
Linked code
- D.
Object code
Correct Answer
D. Object codeExplanation
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.Rate this question:

A finite sequence of precise instructions that leads to a problem solution is
- A.
A program
- B.
The CPU
- C.
A List of Inputs and Outputs
- D.
An Algorithm
Correct Answer
D. An AlgorithmExplanation
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.Rate this question:

Int number;
- A.
Is an output statement
- B.
Is an input statement
- C.
Is a variable declaration
- D.
Is a program
Correct Answer
C. Is a variable declarationExplanation
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.Rate this question:

- D.
Is a program
Correct Answer
B. Is an input statementExplanation
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:

#include <iostream>
- A.
Is a variable declaration
- B.
An executable statement
- C.
An include directive
- D.
Illegal code
Correct Answer
C. An include directiveExplanation
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.Rate this question:

- B.
High-level language
- C.
Low-level language
- D.
Assembly language
Correct Answer
B. High-level languageExplanation
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.Rate this question:
