7. Case Study Modification #2 Modify Program 9-19 (the United Cause case study program) so the arrptr array is sorted in descending order instead of ascending order. also please add as much comments as possible so i can understand what you did

the c++

//system libraries #include #include #include

using namespace std; //user libraries

//global constants only

//Functions prototypes here void arrSele(int *, int); void showArr(const int [], int); void showAPt(int *, int); //Program execution start here int main(int argc, char** argv) { //Declare variables here int num_don;

cout << "Enter the number of donations: "; cin >> num_don;

int *donatio = new int[num_don];

int i = 0; while(i < num_don) { cout << "Enter the donation #" << (i + 1) << ": "; cin >> donatio[i];

i++; } cout << endl;

int *arrPtr = new int[num_don]; //declare dynamic array variable to get the number of donation //input

//process for (int count = 0; count < num_don; count++) arrPtr[count] = donatio[count];

arrSele(arrPtr, num_don);

cout << "The donations, sorted in ascending order, are: "; showAPt(arrPtr, num_don);

cout << "The donations, in their original order, are: "; showArr(donatio, num_don); //output

//Exit return 0; } //to sort the dynamic array //function definitions void arrSele(int *arr, int size) { int startS, minInde; int minElem;

for (startS = 0; startS < (size - 1); startS++) { minInde = startS; minElem = arr[startS]; for(int index = startS + 1; index < size; index++) { if ((arr[index]) < minElem) { minElem = arr[index]; minInde = index; } } arr[minInde] = arr[startS]; arr[startS] = minElem; } }

void showArr(const int arr[], int size) { for (int count = 0; count < size; count++) cout << arr[count] << " "; cout << endl; }

void showAPt(int *arr, int size) { for (int count = 0; count < size; count++) cout << arr[count] << " "; cout << endl; }
