objects of that class become non-copyable. This is particularly useful when our class has pointers or dynamically allocated resources. In such situations, we can either write our own copy constructor like above String example, or make a private copy constructor so that users get ...

We can use default argument in constructor. It must be public type. Example of C++ Constructor #include <iostream>usingnamespacestd;classSample{private:intX;public:// default constructorSample() {// data member initializationX=5; }voidset(inta) { X=a; }voidprint() { cout<<"Value of X...
What is Parameterized Constructor in C++?As the name suggests it's a constructor with arguments/parameters, it follows all properties of the constructor and takes parameters to initialize the data.For Example: If we want to initialize an object with some values while declaring it, we can do ...
Example using namespace std; class City { public: string cityName; //fields int population; City() { //constructor if no input parameters are provided this->cityName = "No city name provided"; this->population = 0; } City(String cityName) { //constructor if only a city name is prov...
Copy Constructor in C++ By Dinesh Thakur Whenever an object is defined and initialized with some values of basic data types passed as arguments. For example : 1 counter c1(10);//creates and initializes object c1 with value 10 However, it is also possible to pass an existing object for ini...
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 created for user-defined types like structures. Let’s have a look at the provided example for creating a pointer for ...
