CompTIA ITF+ Software Development Concepts Questions and Answers

Question 1

A developer is creating a plan for a new application's logic before writing any actual code in a specific programming language. The developer uses a simplified, English-like notation to outline the steps of the algorithm. Which of the following is being used?

Accepted Answer

Pseudocode

Answer

Pseudocode is an informal, high-level description of the operating principle of a computer program or other algorithm. It uses the structural conventions of a normal programming language but is intended for human reading rather than machine reading.

Question 2

A programmer writes a script in a language that is translated and executed line-by-line by another program every time the script is run. Which category of programming language is being used?

Accepted Answer

Interpreted language

Answer

Interpreted languages are processed by an interpreter, which reads and executes the source code line by line without a separate compilation step. This contrasts with compiled languages, which are translated into machine code before execution.

Question 3

Which of the following fundamental programming logic structures is used to execute a block of code only if a specific condition is true?

Accepted Answer

Selection (Conditional)

Answer

The selection, or conditional, structure allows a program to make a decision and follow a different path based on whether a condition is true or false (e.g., using if-then-else statements). Sequence executes steps in order, and loops repeat steps.

Question 4

A software development team is working on a large, complex project with well-defined requirements that are unlikely to change. They decide to use a development model where each phase must be fully completed before the next begins. Which software development model does this scenario describe?

Accepted Answer

Waterfall

Answer

The Waterfall model is a sequential software development process in which progress flows steadily downwards (like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, deployment, and maintenance. This model is best suited for projects with stable and well-understood requirements.

Question 5

In object-oriented programming, what is the concept of bundling data (attributes) and the methods (functions) that operate on that data into a single unit or 'object'?

Accepted Answer

Encapsulation

Answer

Encapsulation is a fundamental concept in object-oriented programming (OOP). It refers to the bundling of data with the methods that operate on that data, and restricting direct access to some of an object's components.
