CarDealership Class The CarDealership class will simulate a real life automotive dealership. This class will create 3 Car objects and store them in an array named Lot. The class will then display all of the information pertaining to each car (color, make, model, etc.) to the User and allow the User to select one to purchase. Once the User selects a car to purchase, the Car object should be removed from the array (Lot) and another Car object should be put in its place.

For any element in keysList with a value smaller than 40, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If keysList = {32, 105, 101, 35} and itemsList = {10, 20, 30, 40}, print: 10,40, #include <iostream>#include <string.h>using namespace std; int main() { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; cin >> keysList[0]; cin >> keysList[1]; cin >> keysList[2]; cin >> keysList[3]; cin >> itemsList[0]; cin >> itemsList[1]; cin >> itemsList[2]; cin >> itemsList[3]; /* Your code goes here */ cout << endl; return 0;}

Javascript toggleCommentSection function The function toggleCommentSection should exist. The function toggleCommentSection should return undefined if not passed a parameter. The function toggleCommentSection should return null if passed a parameter that does not match a post ID. The function toggleCommentSection should select and return the correct section element. The function toggleCommentSection should toggle the 'hide' class on the section The following are requirements of the function toggleCommentSection: element.toggleCommentSection a. Receives a postId as the parameter b. Selects the section element with the data-post-id attribute equal to the postId received as a parameter c. Use code to verify the section exists before attempting to access the classList property d. At this point in your code, the section will not exist. You can create one to test if desired. e. Toggles the class 'hide' on the section element f. Return the section element Here is what I have so far:…
