How To Create Constructor In C++:

In C++ a constructor is a special method of a class or structure in object-oriented programming that initializes a newly created object of that type. Whenever an object is created, the constructor is called automatically. Constructor is used to initializing objects of a class and allocate appropriate memory to objects. That is, it is used to initialize the instance variables of a class with a different set of values but it is not necessary to initialize.

Constructor Types:

  • Default Constructor.
  • Parameterized Constructor.
  • Copy Constructor.
  • Static Constructor.
  • Private Constructor.

Example Of A Constructor:

#include <iostream>
#include <string>
using namespace std;

class Employee
        public: //private: , protected:
        string name;
        int salary;

        Employee(string n, int s, int sp)
            this->name = n;
            this->salary = s;
            this->secretPassword = sp;

        void printDetails()
        cout<<"The name of our first employee is "<< this->name << " and his salary is " << this->salary<<" dollers"<<endl;
    void getsecretPassword()
        cout<<"The secret password is "<<this->secretPassword<<endl;
    int secretPassword;
    class programmer : public Employee  //inheritance
        int errors;

int main()
    Employee ak("akshat constructor", 3000000, 23334);
    return 0;

There are no “return value” statements in the constructor, but the constructor returns the current class instance.
