Array and Pointer of an Object in C++:
Code for Array of an Object.
//Array of an object
#include<iostream>
using namespace std;
class Student
{
char name[20];
int rollno;
float fee;
public:
void input()
{
cout<<"Enter name ";
cin>>name;
cout<<"Enter rollno ";
cin>>rollno;
cout<<"Enter fee ";
cin>>fee;
}
void display()
{
cout<<"\nName is "<<name;
cout<<"\nRollno is "<<rollno;
cout<<"\nEnter fee "<<fee;
}
};//end of class
int main()
{
Student st[2];//array of an object
int i;
for(i=0;i<2;i++)
{
st[i].input();
st[i].display();
printf("\n\n");
}
}//end of main
Output:
Enter name riya
Enter rollno 1
Enter fee 10000
Name is riya
Rollno is 1
Enter fee 10000
Enter name priya
Enter rollno 2
Enter fee 10000
Name is priya
Rollno is 2
