Well, I think that maybe the answer is B or C. She shouldn't only look at her presentation while she is presenting it, that doesn't look professional, and you want to look at the people you are talking to.
Answer:
Following are the code to the given question:
#include <iostream>//header file
using namespace std;
class Window //defining a class Window
{
private:
int width, height;//defining integer variable
public:
friend ostream& operator << (ostream& stm, Window& width)//defining a friend function that takes two parameters
{
return stm<<"a ("<<width.width<<" x "<<width.height<<") window"; //use return keyword that return its values
}
Window(int width, int height): width(width), height(height)//defining parameterized constructor that inherit width and height in its parameters
{}
};
int main() //Main method
{
Window w(80,90);//calling class constructor
cout<<w;//print object value
return 0;
}
Output:
a (80 x 90) window
Explanation:
In the above code, a class "Window" is defined that uses a friend function "ostream& operator" is declared that uses the "ostrea&" as a data type to hold two-variable "stm and w" in its parameter, and declared the parameterized constructor to hold value by inheriting width and height in its parameters.
Inside the main method, a class object is created that calls the constructor and uses the print method to print object value.
Answer:
int costOfBusRental;
int maxBusRiders;
int costPerRider;
costPerRider = costOfBusRental/maxBusRiders;
Explanation:
The costPerRider is the total cost of renting the bus (costofBusRental) divided by all the bus users (maxBusRiders). So we declare the three variables to be of type int as required by the question.
The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches of rain falls yearly. Rain forests belong to the tropical wet climate group.
Explanation:
- The temperature in a rain forest rarely gets higher than 93 °F or drops below 68 °F. The average humidity is between 77 and 88%, rainfall is often more than 100 inches a year. In monsoonal areas, there is a real dry season.
- Rainforests now cover less than 6% of Earth's land surface. Tropical rainforests produce 40% of Earth's oxygen.
- About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine, is used as an anesthetic and to relax muscles during surgery. Quinineis used to treat malaria.
- There are four very distinct layers of trees in a tropical rain forest. They are the emergent, upper canopy, understory, and forest floor.
- The soil of the tropical rainforests is shallow, poor in nutrients and without soluble minerals. Years of rainfall have washed away the nutrients in the soil obtained from weathered rocks.
- The tropical rain forest can be found in three major geographical areas around the world.
-
Central America in the the Amazon river basin. Africa - Zaire basin, with a small area in West Africa. Indo-Malaysia - west coast of India, Assam, Southeast Asia, New Guinea and Queensland, Australia.
