Is there anyone who can do this. I need a algorithm and a flowchart with this program.

I would like a program that will calculate each students average grade for multiple classes. The number of students and the number of classes is unknown. The program should be able to calculates the class average. The program should give me the students id #, average, and letter grade. It should give me the class average and the percentage of students who received a C or better and the number of students who earned the class average or above. I need to know the class median, range, highest and lowest scores. The department will be giving a small scholarship to students who earn an 87.5 or higher in the course. The scholarship will be calculated by multiplying their average by 2.75.

More technical description:

Prompt the professor to enter data for one student at a time including student ID and grades for each student. Prompt the user to enter -1 to show that the user is through entering grades. If the score entered is less than 0 or more than 100, display an appropriate message and do not use the score. After all scores have been entered, display the number of scores, entered, the highest score, the lowest score, and the mean. You should have multiple methods and an array at minimum.
