Answer 1

Answer:

class Student

{

 int Roll;

char name[25];

float weight;

float height;

public:

Student()          

{

  strcpy(Name,"Nikhil");

Roll = 20;

        height = 165.5;

       weight = 58.2;

} ;

void read (){

   cout << "Enter name: " ;

   cin >> name;

   cout << "Enter roll number: ";

   cin >> rollNo;

   cout << "Enter height: ";

   cin >> height;

cout << "Enter weight: ";

   cin >> weight;

}

void display()

{

cout<<"\n\tName : "<<Name;

cout<<"\n\tRoll : "<<Roll;

cout<<"\n\tHeight : "<<height;

cout<<"\n\tWeight : "<<weight;

}  

void main()

{  

    Student s1, s2;

   s1.read();

   s2.read();

   s2.display();

}
