C++ programs can be defined as a collection of objects that interact with each other by calling their methods. Objects Objects have states and behaviors. For example: a dog’s state – color, name, breed; behavior – wagging, barking, eating. Objects are instances of classes. Classes Classes can be defined as templates/blueprints that describe the behaviors/states … Read more
When programming with a programming language, various variables are needed to store different types of information. A variable retains the memory location of the value it stores. This means that when a variable is created, some space is reserved in memory.Various data types (such as character, wide character, integer, floating-point, double floating-point, boolean, etc.) may … Read more
In this topic, we will learn about the free() function and the delete operator in C++. free() Function In C++, the free() function is used to dynamically release memory. It is a library function used in C++, defined in the stdlib.h header file. This library function is used for pointers pointing to memory allocated using … Read more
Storage classes are used to define the lifetime and visibility of variables and/or functions in a C++ program. The lifetime refers to the duration during which a variable remains active, and visibility refers to the modules in the program that can access the variable. In C++ programs, there are five types of storage classes that … Read more

In a program, C++ identifiers are used to refer to the names of variables, functions, arrays, or other user-defined data types created by the programmer. They are a basic requirement of any language. Each language has its own rules for naming identifiers. In short, we can say that C++ identifiers represent the basic elements in … Read more
In C++, a constructor is a special method that is automatically called when an object is created. It is used to initialize the data members of the new object. The constructor in C++ has the same name as the class or structure. In short, when an object is created in C++, a specific process called … Read more
Preface/PREFACE C++ is a mid-level language that was designed and developed at Bell Labs starting in 1979. C++ further expands and improves upon the C language and is an object-oriented programming language. C++ can run on multiple platforms, such as Windows, MAC operating systems, and various versions of UNIX. Firstly The first step in programming … Read more
