Chapter 3, Problem 4PP

(Biology) The number of bacteria, B, in a culture that’s subject to refrigeration can be approximated by this formula:

B = 300000   e 0.032 t

e is Euler’s number 2.71828 (rounded to five decimal places).

t is the time in hours the culture has been refrigerated.

Using this formula, write, compile, and run a C++ program that prompts the user for a value of time, calculates the number of bacteria in the culture, and displays the result. For testing purposes, check your program by using a test input of 10 hours. After verifying your program, use it to determine the number of bacteria in the culture after 12, 18, 24, 36, 48, and 72 hours.

Need a help with this programs for each of the following problem statements:   - USE C++ to solve this. (Dev C++) - use of comment statements- use of descriptive variable names  1. (gcount)  A program that will accept any number of grades foran exam. The grades will be input as 4 for an A, 3 for a B, 2 for a C, 1for a D, and 0 for an F. After all grades have been entered, allow theuser to enter -1 to exit. Output the number of grades in each category. - correct use of array of counters - correct use of loop - correct output
(C PROGRAMMING ONLY) 1. Dealing With Monthsby CodeChum Admin We're done dealing with days. It's time to step up and now deal with months!   Instructions: In the code editor, you are provided with a code in the main() which has 12 printf's. Each printf prints a month with its corresponding value. For this program, January is 1, February is 2, March is 3, and so on. When you run the initial code, you will encounter errors because these month names that have been printed don't exist yet.Your task is to create an enum data type which contains these month names as values so that when we run the code, there will be no more error.Do not edit anything in the main(). Output January = 1February = 2March = 3April = 4May = 5June = 6July = 7August = 8September = 9October = 10November = 11December = 12
(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…
