Question

lTele2 LTE C 21:44 21:44 iCloud [] iCloud corresponding message implement the second version of the program, instead of the array use a doubly linked list ;elements are added in such a way that the list ordering by by group number is number is preserved (inserting a new element after an element that is smaller than a new element and in front of a large element. Write the program in c++ and show me a example of output please General requirements 1.use lines of type char (dynamic,new,or static char[N],it is recommended to use stein functions from the library 2.dynamic data structure (list) is created by the student independently, it is forbidden to use ready-made solutions. Solutions Describe a structure named student containing the following fields full name group number performance in 5 subjects(an array of grades) Write a program that does the following keyboard input of data into an array consisting of a maximum ,making it possible to interrupt the input so that you can not Enter all 10 elements; after the input is finished ,sort the array elements in ascending order of the group number output to the console of the names and initials of all students included in the array ,of the student's average score is more than 4.0; if there are no such students ,output a corresnondina message

Explanation / Answer

1)

#include<iostream>
#include<stdlib.h>
#include<stdio.h>
#include<string>
#define MAX 100
using namespace std;
// Main function definition
int main()
{
// Character array
char characterArray[100];
// Pointer created using malloc() function
char *pointerMalloc = (char *)malloc(sizeof(char));
// Pointer created using new
char *pointerNew = new char[sizeof(char)];
// Accept data
cout<<" Enter a string to check pointer using malloc(): ";
cin.getline(pointerMalloc, 10);
// Clears standard input
fflush(stdin);
// Displays data
cout<<" Data entered (using malloc()): "<<pointerMalloc;

// Accept data
cout<<" Enter a string to check pointer using new: ";
cin.getline(pointerNew, 100);
// Clears standard input
fflush(stdin);
// Displays data
cout<<" Data entered (using new): "<<pointerNew;

// Accept data
cout<<" Enter a string to check character array: ";
cin.getline(characterArray, 100);
// Displays data
cout<<" Data entered (character array): "<<characterArray;
}// End of main function

Sample Run:

Enter a string to check pointer using malloc(): this is.

Data entered (using malloc()): this is.
Enter a string to check pointer using new: This is a test.

Data entered (using new): This is a test.
Enter a string to check character array: Check this test.

Data entered (character array): Check this test.
