Which of the following defines an algorithm?

It is a symbolic representation an algorithm
It is the documentation of program logic
It is a list of the sequence of steps required to solve the problem
It is the actual program code

Correct Answer

A. It is a list of the sequence of steps required to solve the problem

Explanation

An algorithm is a defined set of instructions or steps that are followed in order to solve a problem. It is not a symbolic representation or documentation of program logic, nor is it the actual program code. Instead, it is a clear and organized list of the sequence of steps that need to be taken to solve the problem at hand.

What do mean by incrementing?

Squaring
Adding one
Subtracting one
Setting initial value

Correct Answer

A. Adding one

Explanation

Incrementing means increasing a value by a specific amount. In this case, the correct answer is "Adding one" because when we increment a value, we add one to it. This action of adding one to a value is commonly used in programming and mathematics to increase the value of a variable or a number.

Which of the following defines an algorithm?

It is a graphical representation of a program flow
It is the documentation of program logic
It is a list of the sequence of steps required to solve the problem
It is the actual program code

Correct Answer

A. It is a list of the sequence of steps required to solve the problem

Explanation

An algorithm is a set of instructions or a procedure that outlines a sequence of steps to solve a problem. It is not a graphical representation of program flow or the documentation of program logic. While the actual program code may implement the algorithm, the algorithm itself refers to the logical sequence of steps rather than the specific code. Therefore, the correct answer is that an algorithm is a list of the sequence of steps required to solve the problem.

The programming process is a _______________.

System-development process
Coding process
Testing process
Problem solving process

Correct Answer

A. Problem solving process

Explanation

The programming process involves identifying and analyzing problems, designing solutions, and implementing those solutions through coding. This requires critical thinking, logical reasoning, and problem-solving skills. Programmers need to understand the problem, break it down into smaller parts, and devise an algorithm or plan to solve it. They then translate this plan into code and test it to ensure it functions correctly. Therefore, the programming process can be seen as a problem-solving process.

Who usually provides the problem definition to a programmer?

The system analyst
The program manager
The project manager
A senior programmer

Correct Answer

A. The system analyst

Explanation

The system analyst usually provides the problem definition to a programmer. The system analyst is responsible for analyzing the needs and requirements of a project and translating them into a clear problem statement that the programmer can work on. They gather information from stakeholders, conduct research, and define the scope and objectives of the project. This information is then passed on to the programmer, who uses it as a guide to develop the necessary software solution.

What is used for keeping track of the number of times something occurs in a program?

A loop
A counter
A decision construct
None of the above

Correct Answer

A. A counter

Explanation

A counter is used for keeping track of the number of times something occurs in a program. It is a variable that is incremented or decremented each time a specific event or condition is met. By using a counter, the program can keep track of the occurrence of an event or the number of iterations in a loop, allowing for better control and monitoring of the program's behavior.

In the problem definition, which of the following do we use to describe the output that is to be printed?

Print chart
Display system layout sheet
A record format form
All of the above

Correct Answer

A. Print chart

Explanation

The correct answer is "Print chart" because when describing the output that is to be printed, we typically use a print chart which outlines the format, layout, and content of the printed output. A print chart helps to ensure consistency and accuracy in the printed materials. Display system layout sheet and a record format form may also be used in certain cases, but they are not as commonly used as a print chart.

What do we can an error that occurs while a program is being executed?

Syntax error
Logical error
Execution-time error
Bug

Correct Answer

A. Execution-time error

Explanation

An execution-time error refers to an error that occurs while a program is running. This type of error is different from syntax errors, which are detected by the compiler before the program is executed, and logical errors, which are errors in the program's logic that cause it to produce incorrect results. Execution-time errors can include things like division by zero, accessing invalid memory locations, or encountering unexpected input. These errors can cause the program to crash or produce unexpected results. A bug is a general term that can refer to any type of error in a program, including execution-time errors.

Which of the following procedure can you use to check an algorithm?

Debugging by automated debugger
Desk-checking
Inspection
Consultation

Correct Answer

A. Desk-checking

Explanation

Desk-checking is a procedure that involves manually reviewing and analyzing an algorithm or program step-by-step, usually by using pen and paper. It allows for a thorough examination of the logic and flow of the algorithm, helping to identify any errors or flaws. By carefully tracing the execution of the algorithm, desk-checking can help verify its correctness and efficiency. This process is particularly useful when automated debugging tools are not available or when a deeper understanding of the algorithm is required.
