The manager of the Lakeview Hotel needs a program that evaluates and displays a guest's total bill. Each guest pays a room charge that is based on a per-night rate. For illustration if the per night rate is $100 and the guest stays two nights, the room charge is $200.Customer also can incur a one-time room service charge and a one-time telephone charge.

Consider the following equations. 𝐴 = 2𝑥 𝐵 = 2 cos 𝑥 , 𝑤ℎ𝑒𝑟𝑒 𝑥 𝑖𝑠 10° , 20° , 30° … 180° 𝐶 = ∑ 𝑛 + 5 5 100 𝑛=0 Construct a C++ program to calculate and print out the value of A, B and C by considering the following conditions; 1- User must keyed-in “start” and “stop” to control the program. 2- Use function to display all the above equations. 3- If user keyed-in “function1”, calculate the value of A divided by C for the value of x from 1 to 100. 4- If user keyed-in “function1”, calculate the value of B divided by A for the value of x from 2 to 200.

Create an Investment class that contains fields to hold the initial value of an investment, the 

current value, the profit (calculated as the difference between current value and initial value), 

and the percent profit (the profit divided by the initial value). Include a constructor that 

requires initial and current values and a display function. 

Create a House class that includes fields for street address and square meter, a constructor 

that requires values for both fields, and a display function. 

Create a HouseThatIsAnInvestment class that inherits from Investment and House. It includes a 

constructor and a display function that calls the display functions of the parents. 

Write a main() function that declares a HouseThatIsAnInvestment and displays its values.
