Student Details using constructor and destructor


Write a C++ program to Display Student Details using constructor and destructor. Here’s a Simple program to Display Student Details using constructor and destructor in C++ Programming Language.


What is Class and Objects in C++?


  • Class is a user defined data type, which holds its own data members and member functions, which can be accessed and used by creating instance of that class.
  • The variables inside class definition are called as data members and the functions are called member functions.
  • Class is just a blue print, which declares and defines characteristics and behavior, namely data members and member functions respectively. And all objects of this class will share these characteristics and behavior.

  • Objects are instances of class, which holds the data variables declared in class and the member functions work on these class objects.
  • Each object has different data variables. Objects are initialized using special class functions called Constructors.

Below is the source code for C++ program to Display Student Details using constructor and destructor which is successfully compiled and run on Windows System to produce desired output as shown below :


SOURCE CODE : :


/*  C++ program to Display Student Details using constructor and destructor */

#include<iostream>
using namespace std;

class stu
{
                private:
                    char name[20],add[20];
                        int roll,zip;

                public:
                    stu ();//Constructor
                        ~stu();//Destructor
                        void read();
                        void disp();
};

stu :: stu()
{
        cout<<"\nThis is Student Details constructor called..........."<<endl;
}

void stu :: read()
{
        cout<<"\nEnter the student Name :: ";
        cin>>name;
        cout<<"\nEnter the student roll no :: ";
        cin>>roll;
        cout<<"\nEnter the student address :: ";
        cin>>add;
        cout<<"\nEnter the Zipcode :: ";
        cin>>zip;
}

void stu :: disp()
{
    cout<<"\nThe Entered Student Details are shown below ::---------- \n";
        cout<<"\nStudent Name :: "<<name<<endl;
        cout<<"\nRoll no   is :: "<<roll<<endl;
        cout<<"\nAddress is :: "<<add<<endl;
        cout<<"\nZipcode is :: "<<zip;
}

stu :: ~stu()
{
        cout<<"\n\nStudent Detail is Closed.............\n";
}


int main()
{
        stu s;
    s.read ();
    s.disp ();

    return 0;
}

OUTPUT : :


/*  C++ program to Display Student Details using constructor and destructor */

This is Student Details constructor called...........

Enter the student Name :: CodezClub

Enter the student roll no :: 123

Enter the student address :: India

Enter the Zipcode :: 100215

The Entered Student Details are shown below ::----------

Student Name :: CodezClub

Roll no   is :: 123

Address is :: India

Zipcode is :: 100215

Student Detail is Closed.............

Process returned 0

Above is the source code and output for C++ program to Display Student Details using constructor and destructor which is successfully compiled and run on Windows System to produce desired output.
