C++ templates are a simple yet powerful tool because the idea is to pass data type as the parameter so that we don’t need to write the same code for different data types. Templates make your classes more abstract by letting you define the class’s behavior without knowing how the class operations will handle data … Read more

When one class can access another class’s properties and characteristics, it is called inheritance. Inheritance in C++ Inheritance in C++ is a fundamental concept of object-oriented programming in which when an object of the base class acquires all the properties of the parent object automatically, we can access the features of the parent class with … Read more

A “this” pointer is used to access the object’s address in its class definition. Since you can’t refer to an object in the definition before its creation, “this” pointer comes into use. It helps in referring to the object’s address before its creation. C++ this Pointer this pointer holds the address of the current object, in … Read more

C++ copy constructor is the member function that initializes an object using another object of the same class.  The copy constructor is an overloaded constructor used to declare and initialize an object from another object.   C++ Copy Constructor The copy is the type of constructor which is used to create a copy of the already … Read more

C++ is an object-oriented programming language. Even though it’s not pure, c++ language mainly deals with the OOPS concept. The classes and objects are the most important feature of C++ that leads to Object-Oriented programming. Class is the user-defined data type, which holds its data members and member functions, which can be accessed and used … Read more

The data hiding feature prevents direct access to the internal class representation. Instead, the access restriction uses the class’s private, public, and protected keywords. These keywords, private, public, and protected, are known as access specifiers or modifiers in C++. Access Specifiers in C++ Access Specifiers in C++ are used to define how we will access … Read more

A friend function of the class is defined outside that class’ scope, but it has a right to access all the private and protected members of a class. Even though the prototypes for friend functions appear in the class definition, friends are not member functions. What is the C++ Friend Function? C++ Friend Function is … Read more

C++ constructor is used to initialize the member variables of an instance of a class that is the object of a class. A constructor is a particular type of member function that initializes an object automatically when it is created. The compiler identifies a given member function as a constructor by its name and the … Read more

C++ Array is the collection of items stored at contiguous memory locations. The array is the series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding the index to a unique identifier. Sometimes when writing code, we need to store a lot of data for any … Read more

C++ Heap Sort is a sorting method based on comparisons between the elements. The heapsort is a comparison-based sorting technique based on a Binary Heap data structure. The sorting method works on the principle of binary heap data structure.  The binary heap data structure is much similar to the binary tree. A binary heap is … Read more

Like Bubble Sort, Selection Sort is a sorting algorithm, especially an in-place comparison sort. The selection sort algorithm is based on finding the min or max element or item in the unsorted array and then putting it in its correct position in the sorted array. Selection Sort in C++  Selection sort in C++ is a … Read more
