Before coming to the lab, you should answer the following questions in writing.
1. Write a C++ program that asks users for two
entries of type double, x and y, and then it displays their products.
Your code should have:
1) a function called get_x that asks the users for the value of x, then returns x to the main function.
2) a function called get_y that asks the users for the value of y, then returns y to the main function.
3) a function called mult_xy that takes x and y as its parameters and returns their product to the main function.
Your program must use all three functions.
2. We mentioned that a function can only return
one value using the return statement. Is there any way that a function
returns more than one value? In the above program, could you return
both x and y from one function, let's say get_xy?
3. Can a function call another function? Maybe
this helps you answer this question.
In the following program, is main a function? Does it call another function?
using namespace std;
float divide_xy(int x, int y);
cout << "Enter
2 values for x and y separated by space, then press <Enter> :";
cin >> x >> y;
cout << endl;
qt = divide_xy(x,y);
cout << x << "/" << y << " = " << qt << endl;
float divide_xy(int x, int y)
