For the sorting Choice, do the following: Right after your header file and using namespace std; int sortingChoice; // Declare the functions void SelectionSort(item Type A[], int N); int Min(item Type A[], int i, int N); void InsertionSort(item Type A[], int N); void BubbleSort(item Type A[], int N); In the main: a) Declare the array dynamically (this has been discussed in the class) using pointer b) Allocate memory to N number of data c) Get user inputs (do not initialize the array) using cin statement to fill up the array for all N elements d) Get the value for sortingChoice by properly prompting the user e) Write a switch statement using sorting Choice as controlling parameter, and call SelectionSort for case 1, InsertionSort for case 2, BubbleSort for case 3, and default case display an error message saying that the choice is wrong. Outside the switch statement, display the sorted array with proper title. If you have forgotten how to use switch statement, use the following structure switch(sorting Choice) case 1: SelectionSort(A, N); { break; case 2: InsertionSort(A, N); break; and so on default: cout << "Not a correct choice" << endl; } Then display the sorted array.

This program will display an array being passed to a function, show. The show function will display the elements of the given array. The main program controls the size and the inputs of an array.   // function prototype void show(int [], int); int main(){ const int arraysize=5; int numbers[arraysize]={3,6,12,7,5}; show(numbers,arraysize); // (A) show(numbers,arraysize+1); return 0;}   //function body void show(int nums[], int size){ for (int index=0;index<size; index++) cout<<nums[index]<<endl; } What is the output of this program?  What is the output if modification (A) has been made?

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.

# dates and times with lubridateinstall.packages("nycflights13") library(tidyverse)library(lubridate)library(nycflights13) Qustion: Create a function called date_quarter that accepts any vector of dates as its input and then returns the corresponding quarter for each date Examples: “2019-01-01” should return “Q1” “2011-05-23” should return “Q2” “1978-09-30” should return “Q3” Etc. Use the flight's data set from the nycflights13 package to test your function by creating a new column called quarter using mutate()
