Assume that decSales is an array of 20 Decimal values. Write a statement thatresizes the array to 50 elements. If the array has existing values, they should bepreserved.

Arrays 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:800 775 790 Note: 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++.

Look at the following array definition. int values[10];A) How many elements does the array have?B) What is the subscript of the first element in the array?C) What is the subscript of the last element in the array?D) If an int uses four bytes of memory, how much memory does the array use?

Description Create an application that maintains an array of your home inventory and displays the contents of the array in a list box. For this assignment, we will be using an array. In later chapters, we will modify this application to use a database or an external text file. The application should look like: g My Home Inventory Home Inventory Item Description Ist Homelnventory Serial Number Cost ADD DELETE REFRESH BYE Detailed Instructions 1. Define arrays for Item Description, Serial Number, and Cost after the Public Form Q and before any click of page load events. 2. In the Page Load Event, populate the Home Inventory List Box with the data from the arrays using the format: "ItemDecription (SerialNumber, Cost)". 3. If the ADD button is clicked, add the Item Description, Serial Number, and Cost to the Home Inventory List Box and to the appropriate arrays. 4. If the DELETE button is clicked, remove the item from the Home Inventory List Box and corresponding arrays. 5. If the REFRESH…
