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.
