Object Oriented Programming in C++

Explore constructors in C++, including default, parameterized, and copy constructors, and how they initialize object data members automatically, with syntax inside and outside the class and key behaviors.

Define a destructor as a tilde-named special member function auto-invoked when an object goes out of scope to release memory; it cannot be overloaded and takes no arguments.

Explore inheritance in C++ by defining derived classes from base classes, inheriting members, and learning single, multi-level, hierarchical, multiple, and hybrid inheritance.

Learn single inheritance by showing how a derived class inherits properties from a base class, with class A as base and class B as derived.

Explains multi-level inheritance in C++, where class b is intermediate base between a and c, using an a–b–c chain and grandmother–daughter–child example, plus a program demonstrating add, subtract, and multiply.

Explore multiple inheritance in C++ by deriving a class from multiple base classes, access shared and own members, and review a runnable example with A, B, and C.

Explore hierarchical inheritance in C++, where multiple derived classes share a single base class. Learn the syntax, access patterns, and a full example with classes A, B, and C.

Explore hybrid inheritance in c++, where single, multiple, and hierarchical inheritance combine in a single class hierarchy with A, B, C, and D.

Explore polymorphism in C++, comparing compile-time overloading with runtime dynamic binding via virtual functions, including function overriding and pure virtual concepts.

Learn how function overloading uses the same name with different parameter lists to enable multiple definitions, while the compiler resolves calls by signature matching, type conversions, and avoiding ambiguity.

Explore constructor overloading in c++, using the same class name for multiple constructors with different argument lists, including default and parameterized forms, and learn how objects pick the correct one.

Explore operator overloading in C++, a compile-time polymorphism feature that lets you redefine existing operators for user-defined types, using unary and binary forms and friend functions.

See how virtual functions enable dynamic binding through base class pointers and are overridden by derived classes. Learn how pure virtual functions define abstract base classes that require derived implementations.

Discover how inline functions reduce context switching by substituting code at compile time, compare inline with macros, and learn syntax, limitations, and differences from virtual functions.

Explore how friend functions and friend classes enable non-member access to private and protected members, balancing encapsulation with external utilities through syntax, examples, and advantages and restrictions.

Explore exception handling in C++, learn standard exceptions and their types, including synchronous and asynchronous errors, and how runtime anomalies are detected, grouped, and handled to keep programs robust.

Explore try, throw, and catch in C++ to detect and handle errors, including division by zero, with multiple and nested try blocks, and RAII replaces finally.

Define a custom exception class derived from std::exception, then throw and catch it to handle application-specific errors in C++.

Learn function templates in C++ to write generic, type-safe functions that work on many data types. See syntax, benefits over overloading, and a max template example.

Explore how a class template in C++ lets a single class handle different data types. See an example with template parameters and objects using float and int that display sums.
