Scope Rules of Classes at a Glance
Objects
The declaration of a class does not include objects of that class. It only specifies the type of information the objects of this class type will hold, when created. Objects of a class can be created using the class tag-name as type specifier. The syntax used to declare objects is:
class-name object1, object2, .....objectn;
For example:
class book;
{
public;
int bookno;
float cost;
void getdata(int i, float j)
{
bookno=1;
cost=j;
}
void putdata(void)
{
cout <<"\nBook no:"<<bookno;
cout<<"\nCost:"<<cost;
};
book r1, r2; // objects of type book
int main()
{
r1.getdata(101, 123.50); // Assign values to data members of object r1
r2.getdata(102, 145.50); // Assign values to data members of object r2
r1.putdata(); // display values of r1
r2.putdata(); // display values of r2
}
The public members of an object can be accessed directly by using the objects name and dot(.) operator.
