Move Semantics with std::move
Move semantics allow resources (like heap memory) to be moved from one object to another instead of being copied. std::move casts an object to an rvalue, enabling the move constructor to take over…

Open snippet →std::unique_ptr is a smart pointer that owns and manages another object through a pointer and disposes of that object when the unique_ptr goes out of scope. It cannot be copied, only moved, ensurin…
Open snippet →Lambdas are anonymous functions that can be defined inline. The capture clause '[]' allows the lambda to access variables from the surrounding scope, either by value or by reference.
Open snippet →In C++, if you delete a derived class object through a base class pointer, the behavior is undefined unless the base class has a virtual destructor. Marking it virtual ensures the entire object hie…
Open snippet →Resource Acquisition Is Initialization (RAII) is a core C++ idiom. Resources are tied to object lifetime; they are acquired in the constructor and released in the destructor, ensuring they are neve…
Open snippet →Template Specialization allows you to define a custom implementation of a template for a specific data type, overriding the generic version.
Open snippet →Operator overloading lets you redefine how standard operators like + or - behave when used with your custom classes.
Open snippet →The mutable keyword allows a specific member of a class to be modified even if the object is accessed through a const reference or inside a const member function.
Open snippet →Member initializer lists are used in constructors to initialize class members before the constructor body executes, which is more efficient than assignment.
Open snippet →Static members are shared by all instances of a class. There is only one copy of a static member, regardless of how many objects are created.
