This program will use the concept of arrays.  This is also called subscripted variables.

You will be asked to calculate test average and letter grade for a class of 20-30 students.

Your program will start out by asking how many students in the class.

Must put randomize(); Just after main. Also, #include<stdlib.h>

            cout<<”How many in the class?”<<endl;

      cin>>size;

Now fill the array with random numbers in the range of 45-105.

Use a loop like this…

                                    for(z=0; z<size; ++z)

                     num[z]=random(61)+45;

Whenever I start thinking that I am not living up to my potential, I remind myself of the old farmer and his fight to the death with the insane pig.  It’s an exciting story, and it takes my mind off all this “potential” business.      ~Jack Handey

Determine the letter grade for each person using a switch on the score.

                        for(z=0; z<size; ++z)

            {

            number=floor(num[z]/10)

                  switch(number)

ac is a counter.  Keep count for each grade. Start ac at 0.

                  {

                  case 10:

                  case   9: grade[z]=’A’;

                        ac++;

                        break;
