Master C++ constructors with this comprehensive guide for beginners. Learn to initialize objects, set default values, and perform complex initialization tasks.
Constructor has the same name as the class name. It is case sensitive. Constructor does not have return type. We can overload constructor, it means we can create more than one constructor of class. We can use default argument in constructor. ...
Exception handling in C++ is a mechanism that allows a program to handle errors or exceptional situations during runtime by using try, catch, and throw statements.
A Constructor in C++ is a special member function having the same name as that of its class, which is used to initialize some valid values to an object’s data members. It is executed automatically whenever an object of a class is created. The only restriction that applies to the construc...
The do-while loop in C++ ensures the implementation of the code body at least once, irrespective of whether the condition is met or not. Understand how it works.
Next, the syntax of the parameterized constructor has also been defined, such as “Structure-Name(d_type variable1,…)” represents the parameterized constructor. Note: The “struct” declaration is the same as the declaration of class in C++. Working of “struct” Constructor in C++ In C++,...

A Destructor in C++ is a member function having the same name as that of the constructor. But, it is preceded by a tilde (~) symbol.
It is a special type of class. It is basically created for linked list and tree based implementation in C++. If a class contains the data member as pointer to object of similar class, then it is called a self-referential class.
