A null pointer is a pointer that does not point to any memory location.
Null pointers are used in programming languages to represent that a pointer does not point to a valid object or memory location.
Attempting to dereference a null pointer can result in a segmentation fault or other runtime error.
Example: int* ptr = nullptr; // ptr is a null pointer

Virtual function is a function in C++ that can be overridden in a derived class.
Virtual functions are declared in a base class and defined in a derived class.
They allow polymorphism, where a derived class object can be treated as a base class object.
The virtual keyword is used to declare a function as virtual.
Example: virtual void display() = 0; // pure virtual function
Example: virtual void display() { cout << 'Base cl
A constructor is a special method that is used to initialize objects of a class.
Constructors have the same name as the class they belong to.
They are called automatically when an object of the class is created.
They can be used to set default values for object properties.
Constructors can be overloaded to accept different parameters.
Example: public class Car { public Car() { // constructor code here } }
A destructor is a member function of a class that is responsible for destroying objects of that class.
Destructors have the same name as the class preceded by a tilde (~).
They are called automatically when an object is destroyed or goes out of scope.
They are used to release resources allocated by the object during its lifetime.
Example: ~MyClass() { delete[] myArray; }
Destructors cannot be overloaded or inherited.
Friend class is a class that has access to the private and protected members of another class.
Friend class is declared using the 'friend' keyword.
It allows the friend class to access the private and protected members of the class it is friends with.
Friendship is not mutual, meaning the friend class does not grant access to its own private and protected members.
Friend functions can also be declared to have access to pri...

The width of a tree is the maximum number of nodes at any level in the tree.
To calculate the width of a tree, we can perform a level order traversal and keep track of the maximum number of nodes at any level.
We can use a queue data structure to perform the level order traversal.
At each level, we count the number of nodes in the queue and update the maximum width if necessary.
