A vector can store multiple data values, similar to an array, but they can only store object references and not basic data types. Storing object references means they point to the object that contains the data rather than directly storing the data. Unlike arrays, vectors do not require size initialization. They can dynamically resize based … 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 C++, inheritance is the process by which an object automatically acquires all the properties and behaviors of its parent object. Through inheritance, you can reuse, extend, or modify the properties and behaviors defined in other classes. In C++, a class that inherits members from another class is called a derived class, while the class … Read more
C++ virtual functions are member functions that are redefined in derived classes. They are declared using the virtual keyword. This is used to inform the compiler to perform dynamic linking or late binding on the function. It is necessary to use a single pointer to reference all objects of different classes. Thus, we create a … Read more
