Classes In C Creating Classes Constructors And Using The This Pointers in c and c are often challenging to understand. in this course, they will be demystified, allowing you to use pointers more effectively in your co. Prerequisite: pointers in c a pointer is a data type that stores the address of other data types. pointers can be used for base objects as well as objects of derived classes. a pointer to the object of the derived class and a pointer to the object of the base class are type compatible (may be used in different ways). the pointer of base class poi. C constructors. a constructor is a special member function that is called automatically when an object is created. in c , a constructor has the same name as that of the class, and it does not have a return type. for example, class wall { public: create a constructor. wall() {. Num = obj.getnumofcities(); std::cout<<"\n number of cities is equal to "<<num; return 0; } in the example above : the name of the class is country. observe that there are two functions with same name as that of class ie country. the function that have a ‘~’ before the name is destructor while the other one is constructor.

Got it. constructor in c is a special method that is invoked automatically at the time an object of a class is created. it is used to initialize the data members of new objects generally. the constructor in c has the same name as the class or structure. it constructs the values i.e. provides data for the object which is why it is known as a. On line 1, you are creating an a object, calling the a constructor, passing in 1, and assigning it to a1. on line 2, you are making a copy of a1. on line 3, you are creating a new a object, calling the a copy constructor, passing in the copied object a1, and returning a pointer to this object in memory. edited jun 15, 2010 at 6:52.
