Write a method ReadPoints to read the student's grade points in the various subjects.
You should save the points in an array, vector or list.
When the method is called, the user must enter a number of grade points.
The grade points to be entered are controlled by the contents of the subject field.

Write a method that will convert the points into grades according to the scale A-F.
The grade A corresponds to 100 points.
The grade F corresponds to less than 50 points
You must store the grades in a field (array, vector or list).


Write a method printPrintGrades that prints the grades.
Write a method Statistics that will calculate the number of "A", "C" and "F" grades and the total number of grade points.
When the Statistics method is called, the grade statistics must be printed.
Write pseudocode for this method. Also draw flow charts.

You don't need to write pseudo code or draw flow diagrams for the entire program.
Compile and run the program.
