This C++ program will demonstrate how to access the Data Members of a class.
#include <iostream>using namespace std;
class Box {
public:
double length;
double breadth;
double height;
};
int main( ) {
Box MyBox;
double volume; //for storing volumne of box
// MyBox initialization
MyBox.height = 2;
MyBox.length = 3;
MyBox.breadth = 5;
/* Note: public data members of objects of a class
can be accessed using direct member access operator "."
*/
// volume of MyBox
volume = MyBox.height * MyBox.length * MyBox.breadth;
cout << "Volume of MyBox = " << volume <<endl;
return 0;
}
Output of program
Volume of MyBox : 30
