- Reverse ArrayWrite a function that accepts an int array and the array’s size as arguments. The function should create a copy of the array, except that the element values should be reversedin the copy. The function should return a pointer to the new array. Demonstrate thefunction in a complete program.Exercise 1: //The max function the max between a and b, it returns a if a == //b public double max(double a, double b); //The mult function returns the result of a * b public double mult(double a, double b); //The exist in array function returns the index of the element //‘a’ if //‘a’ exist in array ‘arr’ otherwise returns ‘-1’ public int existsInArray(int [] arr, int a); //Are array equals method compares two arrays and returns true // if the elements of array ‘a’ are equal to elements of array // ‘b’, element by element. If equals it returns 0, it returns - // 1 if not public int areArrayEquals(int [] a, int [] b); Devise four executable test cases for every method in the JUnit notation. See the attached handout for a refresher on the notation.Randomly generate a partially filled array of unique values.a) Create a blank partially filled integer array of capacity 10.b) Implement an array print function.c) Implement a hasValue function which accepts the array and an integervalue as input. It checks the array for the value and returns trueif the value exists, false if it does not.d) Implement a randArray function which initializes the array with randomintegers between 0 and 9 inclusive. This function should use thehasValue function to ensure all values are unique (no duplicates).e) Print the array. Confirm that all values (0-9) are included. Example 1 Output (input in bold italics) 2 5 8 9 3 4 0 1 7 6Example 2 Output (input in bold italics)5 9 3 4 7 0 1 6 2 8
- Description of the assignment: Your program should read in a set of grades (that are all integers) entered by the user. The user will signify the end of the list of grades by entering -999. Do NOT process this value. You can assume that the user will enter at least three grades and not more than 100 grades, all of which will be integers in between 0 and 100, inclusive. For the set of grades, your program should compute the minimum value, print this out to two decimal places and remove it from the data. Then your program should compute the maximum value, print it out to two decimal places and remove it from the data. Then, your program should calculate the mean and standard deviation for the remaining set of grades, and print these out to two decimal places. Finally, a histogram for this data (without the highest and lowest grades) should be printed out as well. Your program should include the following functions: void readGrades (double grades [], int *n); /* This function reads an…JAVA CODE PLEASE Functions with 2D Arrays Practice ll by CodeChum Admin Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array.

- Program in C language (Please solve part 2) Part one : Write a program that does the following: Creates int array array_1 of length 10. Creates int array array_2 of length 10. Takes int values from the user of for 10 values for array_1 and array_2, each. Creates a new int array array_3 which copies the values of array_1 and array_2, in interleaved order, into it. Prints out the contents of Prints out the contents of array_1, array_2 and array_3. Part two : Repeat Part one, but this time use arrays of char (instead of int), and stop receiving input into array_1 and array_2 when the user hits Enter / newline and insert a Null character into the array// New Function prototypes void showValues(const int *, int); // display 10 numbers in a line from the array void fillArray(int *, int, int, int); // fill out random numbers between low and high into the array bool searchValue(const int *, int, int); // search value from the array void sortArray( int *, int); //sort the array in an ascending order void swap(int *, int *); //swap the values Modify the code below to create 50 random numbers instead of 10 and use the above new function protoypes. In the output, remove the display of the minimum, maximum and average from the array. Modify the showValues() function to display 10 numbers in a line from the array. [Part 2] Add the two functions to sort an array in an ascending order: void sortArray(int*, int); //ascending ordervoid swap(int*, int*); In the sortArray() function called the swap() function to swap the values from two elements in the array.

- Assignment Write a program that reads a 2D array of chars, checks, and corrects each char within this array, and print out the corrected 2D array. First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. • If the row index is an even number, a char can only be a lowercase English value. • If the row index is an odd number, a char can only be ?, 7', or X'. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen. NOTE: Checking the correctness of a char and correcting it (if necessary) MUST be done in the function with a…Two dimension array in C:Create a two dimension array of integers that is 5 rows x 10 columns.Populate each element in the first 2 rows (using for loops) with the value 5.Populate each element of the last three rows (using for loops) with the value 7.Write code (using for loops) to sum all the elements of the first three columns and output thesum to the screen. without using #defineGiven the following struct definition; #define MAX 20 typedef struct{ int items[MAX]; int count;}Array;Define the functions:void addItem(Array *a, int item); // adds item to the arrayvoid printArray(Array a); // displays elements of itemsint isFull(Array a); //returns 1 if the items is full; 0 if otherwiseint isEmpty(Array a); //returns 1 if the items is empty; 0 if otherwise
