C++ Basic to Advanced Core Concepts Study Guide

What is a variable in C++?

A variable in C++ is a storage location identified by a name that can hold a value and may be changed during program execution.

What is a function in C++?

A function in C++ is a block of code that performs a specific task, can take inputs (parameters), and may return a value.

What are conditional statements?

Conditional statements are programming constructs that allow for decision-making in C++ programs, enabling the execution of different code based on conditions (e.g., if, else if, else).

What is object-oriented programming (OOP) in C++?

OOP in C++ is a programming paradigm that uses 'objects' to represent data and methods; it encompasses concepts such as encapsulation, inheritance, and polymorphism.

What is a class in C++?

A class in C++ is a user-defined data type that serves as a blueprint for creating objects, encapsulating data and functions (methods) that operate on that data.

What is inheritance in C++?

Inheritance is an OOP concept in C++ that allows a class (derived class) to inherit properties and behaviors (methods) from another class (base class), promoting code reuse.

What is polymorphism in C++?

Polymorphism is the ability to present the same interface for different underlying data types; it allows methods to do different things based on the object that it is acting upon.

What is a pointer in C++?

A pointer in C++ is a variable that stores the memory address of another variable, allowing for dynamic memory management and direct memory access.

What is a template in C++?

Templates in C++ allow for the creation of generic functions or classes that work with any data type, enabling code reusability and type-safe programming.

What is exception handling in C++?

Exception handling in C++ is a mechanism to handle runtime errors using try, catch, and throw keywords, ensuring the program can continue or terminate gracefully when errors occur.
