The problem should be solved in C++ programming language

Question 4 A. New programmers often have a problem determining when an argument should be passed to a function by reference and when it should be passed by value. The problem is further compounded by the fact that if a value must be "sent back to the calling function there are two ways to do it: by using a reference parameter or by using a return statement. Provide some general guidelines. [5 marks] B. A weather analysis program uses the following array to store the temperature for each hour of the day on each day of a week. int temp[7][24]; Each row represents a day (0 = Sunday, 1 = Monday, etc.) and each column represents a time (0 = midnight, 1 =1 a.m., ... , 12 = noon, 13 = 1 p.m., etc.). i) Write code to find Tuesday's average temperature.

The date June 10, 1960, is special because when we write it in the following format, the month times the day equals the year. 6/10/60 Write a program that asks the user to enter a month (in numeric form), a day, and a two- digit year. The program should then determine whether the month times the day is equal to the year. If so, it should display a message saying the date is magic. Otherwise, it should display a message saying the date is not magic. [7 marks]
