An example of a string is Hello world. Strings are sequences of characters that can include letters, numbers, symbols, and spaces, and they are typically enclosed in quotation marks. The other options (@, 7, $) represent individual characters or a number, not a full string.
The Boolean operation that returns True only if both conditions are True is AND. In an AND operation, both operands must be True for the result to be True; if either operand is False, the result will also be False.
In pseudocode, the symbol || represents Logical OR. This operator is used to combine two conditions, and it returns True if at least one of the conditions is True.
An array is a special type of variable that holds many values at once. It is a data structure that allows you to store multiple values of the same type in a single variable, making it easier to manage and access related data.
For an array to be multidimensional, it can hold arrays within arrays. This means that it can be structured in more than one dimension, such as a two-dimensional array (like a matrix) or three-dimensional array, allowing for the organization of data in a grid or cube format.
Object-oriented programming (OOP) is a way to model real-world objects in computer code. It uses concepts such as classes and objects to encapsulate data and behavior, allowing for more organized, reusable, and modular code. OOP helps in representing complex systems by creating models that reflect the relationships and attributes of real-world entities.
In object-oriented programming (OOP), a class is a blueprint or template for creating objects. It defines the properties (attributes) and behaviors (methods) that the objects created from the class will have.
Debugging is fixing mistakes in code. It involves identifying and resolving errors or bugs in a program to ensure it runs correctly and efficiently. This process can include testing, diagnosing issues, and modifying the code to correct any problems.
A function in programming is a piece of code that does one specific job. It is designed to perform a particular task, can take inputs (arguments), and may return an output. Functions help in organizing code, promoting reuse, and improving readability.
A function call in programming is a command to run another part of the program and return. It invokes a function that has been defined elsewhere in the code, allowing the program to execute the function's instructions and, if applicable, return a result.
