student-grades

A program using single-dimensional arrays to accept and analyze student grade data.

Assignment

Write a program that accepts a number of grades, prints each grade's letter grade equivalent, the high and low grades and the average of the number of grades entered.

Constraints

• The user can enter a number of grades from 1 to 99.
• The user can run the program as many times as they wish.

Requirements

• Ask the user for a number of grades between 1 and 99.
• Use that number to allocate the size of a single-dimension array.
• Implement five methods that do the following:
  1. Accepts the array and randomly selects grades (of type double) between 55 and 100 and places them into the array.
  2. Outputs each grade from the array, assigning it a number and a letter grade in the following format: "Grade 1: 69.74 is a C-"
  3. Outputs the lowest grade from the array.
  4. Outputs the highest grade from the array.
  5. Outputs the average of the grades from the array.
• Only method 2 can be a void method. The others must return a value.
• Implement a loop to allow the user to repeat the program.
• Use formatted output.
• Round results to 2 decimal places.

Notes

• Round values when determing letter grades.
• Output should begin with 1, not 0 ex: "Grade 1..."
