- Which statement is correct?int[] n = { 16, 3, 7, 18, 21 };int[] m = n; Question 6 options: The variable m references a new array that is an exact of copy of n. Both n and m are variables that reference the same array. This is how you copy an existing array to a new one. The contents of n is copied to m.Question: Get a series of numbers from the user. Let the user determine how many numbers to enter. Set an upper and lower limit for the number that will be array size. If the user enters the number as outside that range, ask him to enter the number again, with an error message on the screen until the correct number is entered. Calculate the largest and smallest elements, sum and average of the array created with the numbers entered by the user, using functions. Print the results obtained on the screen. Also get another input from the user. Use a function to calculate how many characters this input has, how many characters are letters, how many characters are numbers and how many characters are other characters. Print the results on the screen.GIven the statement below: intA=(3,6,9}, A.length can't be used to display the number of elements in the array True False
- EX15: write a program that return (1) when input number odd return (2) when input number is even 5/7 EX16: write a program that separate the content of a input array (a) into two arrays; (x) : contain the 6/7 numbers with odd index and other array (y) contain numbers with even index . EX17:let you have array A[20], write a program that read the array and swap the content of odd index with 7/7 the content of even index .A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. Write a program that asks the user to input an integer greater than 1, then display all of the prime numbers that less than or equal to the number entered. The program should work as follows: • Once the user has entered a number, the program should display an array with all of the integers from 2 up through the value entered. • The program should then use a loop to step through the array. The loop should pass each element to a method that displays the element whether it is prime number. Your result should look like, for example: Enter an integer greater than 1: 9 2, 3, 4, 5, 6, 7, 8, 9 2 is prime 3 is prime 4 is not prime 5 is prime 6 is not prime 7 is prime 8 is not prime 9 is not prime Using java programmingYou can copy all elements of one array into one another with an assignment statement. True or False
- Given the following array declaration:int array[30];Note that you DON’T know the values in the array.Use a for loop to increment the contents of the even indexed (0, 2, 4, 6, 8 …) elements by the value of 4.Output the first component of array.Set of the value of the fourth component of array to 7 multiplied by the value of the 30th component of array plus 8.Problem2 Write a program that display the position of a given element in an array. You should print the index (i.e. the position) of the element. If the element appears more than one time than you should print all its positions. The size of the array should be entered by the user. If the element does not occur then you should display element not found. Sample1: Enter the size of the array: 5 Enter an array of size 5: 44 5 13 44 67 Enter the element to find: 44 44 is found at position 44 is found at position 44 occurs 2 time(s) Sample2: Enter the size of the array: 4 Enter an array of size 4: 12 150 17 20 Enter the element: 18 18 is not foundArrays Write three statements to print the first three elements of array runTimes. Follow each statement with a newline. Ex: If runTime = {800, 775, 790, 805, 808}, print:800 775 790Note: These activities will test the code with different test values. This activity will perform two tests, both with a 5-element array (int runTimes[5]). See "How to Use zyBooks".Also note: If the submitted code tries to access an invalid array element, such as runTime[9] for a 5-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() {const int NUM_ELEMENTS = 5;int runTimes[NUM_ELEMENTS];int i; for (i = 0; i < NUM_ELEMENTS; ++i) {cin >> runTimes[i];} /* Your solution goes here */ return 0;} Please help me with this problem using c++.
- The array index can be any integer less than the array size… TRUE OR FALSEFor the array ADT, the operations associated with the type array are: insert a value in the array, delete a value from the array, and test whether a value is in the array or not. 1.true 2.falseRetailItem Class Write a class named Retailltem that holds data about an item in a retail store. The class should have the following fields: • description. The description field references a String object that holds a brief description of the item. • unitsOnHand. The unitsOnHand field is an int variable that holds the number of units currently in inventory. • price. The price field is a double that holds the item's retail price. Write a constructor that accepts arguments for each field, appropriate mutator methods that store values in these fields, and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three RetailItem objects and stores the following data in them: Description Units on Hand Price Item #1 Jacket 12 59.95 Irem #2 Designer Jeans 34.95 [rem #3 Shirt 24.95
