Question

(C++ OOP) We have a house with 3 rooms.We need the user to enter 1 integer as the window number, 2 doubles as depth and width of the room, 1 double as the useless area, 1 boolean as the door's opening direction (e.g. 0 is outward).Program will compute and print the air condition as a string and the total useful area of the house as a double. Calculating the air condition: Name it air_c. Divide the useful area by the window number. If air_c >20, output "bad". If air_c <11 output "good". If 11<=air_c<=20, output "ideal". Attention: If the window number is 0, air condition is bad. Calculating the useful area of room: Width*Depth-(useless area)if the door is inward;Width*Depth-(useless area)-0.8The worst air condition of the 3 is the final air condition of house. --- 1)The information about the home must be all private within a class.2)The class must get these inputs within constructor func.3)Calculating the useful area of a room must be done within a function of a class.4)Air…

(a)

Program Plan Intro

Program plan:

In the coding window, write the necessary code:

Declaring four int variables a=1, d=1, n=100 and sum.

To calculate the sum of integers from 1 to 100.

To display the calculated sum to user.

Program description:

The main purpose of the program is to calculate the sum of integers from 1 to 100. In the main method, calculating the sum of integers from 1 to 100 and finally, displaying the output, total sum of integers from 1 to 100 to user.

(b)

Program Plan Intro

To verify the results produced by above program and then using the above program to calculate sum of integers from 100 to 1000, with a=100, d=1and n=1000.

(Mathematical functions) a model of worldwide population, in billions of people, is given by this formula. Population = 6.0e0.02t Where t is the time in years (t=0 represents january 2000 and t = 1 represents january 2001). Using this formula, write a c++ program that displays a yearly population table for the years january 2005 through January 2010.
