Scripting-and-Programming-Foundations Exam Questions Dumps

At its core, a programming language includes syntax (rules for writing code), semantics (meaning of the code), and grammar (structure of the code). You’ll use these to write instructions that a computer can understand and execute.

Variables are like containers that store data values. You can think of them as labeled boxes where you can put different types of information, like numbers or text, and then use or modify that information throughout your program.

A loop repeatedly executes a block of code as long as a condition is true, like a for or while loop. A conditional statement, like an if statement, allows your program to execute different blocks of code based on whether a condition is true or false.

A function is a reusable block of code that performs a specific task. You define it once and can call it whenever you need to perform that task, which helps keep your code organized and avoids repetition.

Debugging is the process of finding and fixing errors or bugs in your code. It involves identifying what’s causing the problem and correcting it so that your program runs as expected.

Comments are notes in your code that are not executed. They help explain what your code is doing or why certain decisions were made, making it easier for you and others to understand and maintain the code.

Data types define what kind of data a variable can hold, such as integers, floating-point numbers, strings, or booleans. They help the programming language understand how to interpret and manipulate the data.

A while loop continues executing as long as a specified condition is true, which is useful for scenarios where the number of iterations isn’t known beforehand. A for loop is typically used when the number of iterations is known or finite.

An algorithm is a step-by-step procedure or set of rules for solving a specific problem or performing a task. It’s like a recipe that guides you through a series of actions to achieve a desired outcome.

Error handling involves using constructs like try and catch blocks (in languages like Python or Java) to manage and respond to runtime errors, preventing your program from crashing and allowing for graceful error recovery.
