Step-by-step explanation:
Sure! Here's an example program in C++ that uses classes and objects to calculate the area and volume of a room:
```cpp
#include <iostream>
class Room {
private:
double length;
double width;
double height;
public:
void setDimensions(double len, double wid, double hei) {
length = len;
width = wid;
height = hei;
}
double calculateArea() {
return length * width;
}
double calculateVolume() {
return length * width * height;
}
};
int main() {
Room room;
double length, width, height;
std::cout << "Enter the length of the room: ";
std::cin >> length;
std::cout << "Enter the width of the room: ";
std::cin >> width;
std::cout << "Enter the height of the room: ";
std::cin >> height;
room.setDimensions(length, width, height);
double area = room.calculateArea();
double volume = room.calculateVolume();
std::cout << "The area of the room is: " << area << std::endl;
std::cout << "The volume of the room is: " << volume << std::endl;
return 0;
}
```
In this program, we define a class called "Room" that has private member variables for the length, width, and height of the room. We also have public member functions to set the dimensions of the room, calculate the area, and calculate the volume.
In the main function, we create an object of the Room class called "room". We then prompt the user to enter the length, width, and height of the room. These values are set using the setDimensions function of the room object.
Next, we call the calculateArea and calculateVolume functions of the room object to compute the area and volume, respectively. These values are stored in the variables "area" and "volume".
Finally, we display the calculated area and volume to the user using cout.
