The “Rule of Five” in C++ refers to a guideline for implementing the five special member functions in a class when managing resources. These special member functions are: The Rule of Five suggests that if you need to explicitly define Read More …

The “Rule of Three” is a guideline in C++ that suggests implementing three special member functions when you have a user-defined class that manages dynamically allocated resources. These special member functions are the destructor, copy constructor, and copy assignment operator. Read More …

A smart pointer is a class template that provides automatic memory management for dynamically allocated objects. It helps prevent memory leaks by automatically deallocating the memory when it’s no longer needed. The two commonly used smart pointers in C++ are Read More …

A lambda function is an anonymous function that you can define inline within your code. It allows you to create a function object on the fly without explicitly defining a named function. Lambda functions are useful when you need a Read More …

reinterpret_cast is a type of casting operator that allows you to convert a pointer of one type to a pointer of another type, or to convert an integral type to a pointer type and vice versa. It is considered a Read More …

In C++, dynamic casting is a type of casting that allows you to perform runtime type checking and safely convert pointers or references of a base class to pointers or references of a derived class. It is primarily used in Read More …

In C++, static casting is a way to explicitly convert one data type to another. It is a compile-time cast that can be used when there is a known relationship between the source and target types. Static casting allows conversions Read More …

In C++, object slicing refers to a situation where you assign an object of a derived class to an object of its base class, resulting in the loss of derived class-specific information. This occurs when you assign or pass an Read More …

In C++, a virtual base class is a base class that is designed to be shared among multiple derived classes in a class hierarchy. It is used to avoid the “diamond problem” that can occur when multiple inheritance is used. Read More …

In C++, a diamond problem occurs when a class inherits from two or more classes that have a common base class. This can lead to ambiguity and conflicts in the derived class due to multiple inheritance paths. To illustrate this, Read More …
