Aim: Write a program to show the use of parameterized and with no

argument constructor?

Ans:

#include<conio.h>

#include<iostream.h>

#include<string.h>

class student

{

int rollno;

char branch[20],name[20];

public:

            student()

            {

                        clrscr();

                        cout<<"Enter rollno , branch, name\n";

                        cin>>rollno>>branch>>name;

                        cout<<rollno<<" "<<branch<<" "<<name;

                        getch();

            }

            student(int x,char *y,char *z)

            {

                        rollno=x;

                        strcpy(branch,y);

                        strcpy(name,z);

                        cout<<"\n"<<rollno<<" "<<branch<<" "<<name;

                        getch();

            }

}m,n(56,"cse","abc");

void main()

{

}
