Write the pseudo codes for the following: a. (Counter Controlled) A class of ten students took a quiz. The grades (integers in the range 0 to 100) for this quiz are available to you. Calculate and display the total of all student grades and the class average on the quiz. The class average is equal o the sum of the grades divided by the number of students. The algorithm for solving this problem on a computer must input each of the grades, calculate the average and print the result. b. (Sentinel Controlled) Develop a class average program similar to (1-a) that process grades for an arbitrary number of students each time it is run. 2. Write C++ programs to do question 1
