An object in C++ is a particular instance of a class. It is generated using the class’s constructor function and, aside from having its own set of data and functions, is just a duplicate of the class. Using the Person class’s previous example, here is how to build a Person class ob...
It is used to initialize the data members of an object, with specific values that the user provides. Example: class Intellipaat { public: int value; string name; Intellipaat(int n, string str) { // parameterized constructor value = n; name = str; } }; Copy Constructor: A C++ copy ...

This case is so prevalent that often we don’t even consider there to be a distinction; we look at the variable name as though it were the object itself. This name can only ever refer to one object.[sourcecode language=”cpp”] //create an integer object, refer to it with the name...
NULL - cppreference.com (C++) C++ requires that macro NULL to be defined as an integral constant expression having the value of 0. So unlike in C, NULL cannot be defined as (void *)0 in the C++ standard library. ...
How to Create Pointers for Structure Constructor in C++? A pointer is a variable that is utilized for storing an object’s memory address. In C++, pointers are also used for iterating over an array’s elements or other data structures and many more purposes. Pointer variables are also create...
If an exception occurs while constructing an object, then the object might be only partially constructed. Some of its members might have been initialized, and others might not have been initialized before the exception occurs.Even if the object is only partially constructed, we are guaranteed that...
