Your task is to create two classes namely data and calculation. The calculation class is a friend of the data class. The data class will be composed of two floating point data members namely a and b. The class will also be composed of a friend function display that can display all the data members.

C++ programming It has been observed by management that some faculty member at the university demonstrates a lackadaisical attitude toward work. They seldom go to class yet at the end of each month they receive full salary. Management has decided that GHs 200, 300, 400, and 500 will be deducted from a faculty’s salary if he/she offends once, twice, third time and forth time respectively in a month. This means that if a faculty member offends once in a month GHs 200 will be deducted, if a faculty member offends twice in a month, GHs 500 (i.e. 200+300) will be deducted, if a faculty member offends three times in a month GHs 900 (i.e.200+300+400), will be deducted and if a faculty member offends four times in a month GHs 1,400 (i.e. 200+300+400+500). Assuming all faculty members are on a flat salary rate of GHs 2500. a. Write a program to request for the names of four faculty members and number times he/she has absented him/herself from class. One of them should have absented him/herself…

Custodial staff needing to clean bathrooms in a building that is not closed often use some version of the following process: first, they set up a sign or marker indicating that the bathroom is closed; then, they wait for everybody using the bathroom to finish and leave; once it's empty, they clean the room; and finally they reopen it for general use. Obviously, nobody that's already in the bathroon gets kicked out, but someone arriving after the sign is up will have to go find another batbroom even if the cleaning hasn't started yet.This algorithm is a solution to a resource access-synchronisation problem: specifically, the controlled resource is the bathroom, and the problem and solution are related to the readers-writers problem. Pseudocode:We can describe this algorithm using two semaphores: a binary semaphore called "mutex" and a counting semaphore called "empty"-When the custodial staff enters the bathroom, they acquire the mutex semaphore to ensure that they have exclusive access…
