Functions with 2D Arrays in Java 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. Separate every row by a new line and every column by a space. In the main function, call the displayElements function and pass in the required parameters. Output 1 2 3 4 5 6 7 8 9

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.
Use C++ programing language Write a modular program that analyzes a year’s worth of rainfall data. In addition to main, the program should have a getData function that accepts the total rainfall for each of 12 months from the user and stores it in an array holding double numbers. It should also have four value-returning functions that compute and return to main the totalRainfall, averageRainfall, driestMonth, and wettestMonth. These last two functions return the number of the month with the lowest and highest rainfall amounts, not the amount of rain that fell those months. Notice that this month number can be used to obtain the amount of rain that fell those months. This information should be used either by main or by a displayReport function called by main to print a summary rainfall report similar to the following: 2019 Rain Report for Springdale County Total rainfall: 23.19 inches Average monthly rainfall: 1.93 inches

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.
1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.
Subject : Programming Language C + + Question: Write a program with a function which accepts an array of integers and a key value.The function should return the sum of all the multiples of the key value in the array. For example, for the array {1, 4, 10, 12, 15, 20, 22} and the key value 5, the function should return the sum 10+15+20.
Create a dynamic array that contains an int array. dynamic array, array inside when the existing array is full and a new element needs to be added will double its size, make all the elements of the old array the same will copy the indexes and add the element to the new array. Use the following functions. Write in C language. 1.append(dynamic array, new element): function sent to itself Adds the element sturct to the end of the array inside DynamicArray. Place If not, it behaves in accordance with the dynamic array definition given above. 2. get(index): The element in the index sent to it by the function takes it from the array it hosts and sends it back. ATTENTION ! : Please use a dynamic array and this array with struct structure. I don't want a link list. Do not post wrong or copied codes.

3) Create a function named "makeThemOdd". The function should accept a parameter named "numberArray". Use the higher order function map() to create a new array that contains all the numbers from the original parameter array but adds 1 to each even number. The new array should only have odd numbers in it. Return the new array. // Use this array to test your function:const testingArray = [1, 2, 4, 17, 19, 20, 21];
