True or False Objects that are instances of a class can be stored in an array.
8. Grade Book
A teacher has five students who have taken four tests. The teacher uses the following grading
scale to assign a letter grade to a student, based on the average of his or her four test scores:
Test Score
Letter Grade
90–100
A
80-89
B
70-79
C
60-69
D
0-59
Write a class that uses a String array or an ArrayList object to hold the five students' names,
an array of five characters to hold the five students' letter grades, and five arrays of four
doubles each to hold each student's set of test scores. The class should have methods that
return a specific student's name, the average test score, and a letter grade based on the average.
Demonstrate the class in a program that allows the user to enter each student's name and his
or her four test scores. It should then display each student's average test score and letter grade.
Input Validation: Do not accept test scores less than zero or greater than 100.
C Program
It is the value that is automatically assigned to the remaining elements of the array when the initialize list is less than the size.

If they enter something that is not an integer, you should present them with a meaningful error message and force them to try again as many times as necessary. Once they have correctly entered five integers, you should thank them and then display the integers they entered. You should write a main method but don’t worry about class declarations or imports. Here is an example dialog with the user. Your output does not have to look exactly like this: Enter an integer: 5 Enter an integer: two Not an integer. Try again. Enter an integer: 2@ Not an integer.

- Arrays An array is a sequence of data items that are of the same type, that can be indexed, and that are stored contiguously. Typically, an array is called a data structure used to represent a large number of homogeneous values. The elements of an array are accessed by the use of subscripts. Subscripts start from zero and runs until less than the size of the array. Arrays of all types are possible, including multi-dimensional arrays. Strings are just arrays of characters terminated by a special character called the null character. A typical array declaration allocates memory starting from a base address. The array name is in effect a constant pointer to this memory address. a) Write a complete C program that demonstrates usage of a one-dimensional array of integers. The program should declare an array of a specific size first, and then should ask user to specify values to be stored to the array. The program should finally display all values from the array to the screen for checking if…arrow_forwardAll arrays in C# have a that is set to the array's number of items.arrow_forwardQUESTION 1 Constructors are automatically inherited when we extend a class.
