Re-write your program "List of Chores" using a unique_ptr object as your data member. You should store a dynamic array in the unique_ptr object. Use this array for storing, retrieving, deleting and updating chores.

I am using visual studios to do this problem. I've been out with the flu for the past few days and our book does not cover unique_ptr. The assignment is due tm and I have no clue where to begin. Here is the code I have that works. This is without making any changes yet.

#include "stdafx.h"

#include

#include

#include

using namespace std;

string* reserve(string* arr, int& cNum)

{

string* newArr = new string[cNum + 1];

copy(arr, arr + cNum, newArr);

cNum = cNum + 1;

return newArr;

}

int main()

{

int cap = 1;

int numChores = 0;

string* chores = new string[cap];

ifstream inFile;

ofstream outFile;

inFile.open("input.bat");

if (!inFile)

{

cout << "File did not open correctly!!" << endl;

exit(1);

}

string inputLine;

while (getline(inFile, inputLine))

{

if (numChores == cap)

chores = reserve(chores, cap);

chores[numChores] = inputLine;

numChores++;

}

while (true)

{

cout << endl;

cout << "To add a chore,----------------------PRESS 1!!" << endl;

cout << "To display the number of chores,-----PRESS 2!!" << endl;

cout << "To print the chores list,------------PRESS 3!!" << endl;

cout << "To delete an chore,------------------PRESS 4!!" << endl;

cout << "To exit the program,-----------------PRESS 5!!" << endl;

int userInput;

cout << "Please enter your choice now!! " << endl;

cin >> userInput;

string curChore;

int cnt = 0;

switch (userInput)

{

case 1:

cout << "Enter the chore that needs to be executed!!" << endl;

getline(cin, curChore);

getline(cin, curChore);

if (numChores == cap)

chores = reserve(chores, cap);

chores[numChores++] = curChore;

break;

case 2:

cout << endl;

cout << "The number of chores in the list is " << numChores << "." << endl << endl;

break;

case 3:

cout << "******LIST OF CHORES****** " << endl;

for (int index = 0; index < numChores; index++)

{

cout << chores[index] << endl;

}

break;

case 4:

cout << endl;

cout << "Which chore would you like to delete? " << endl;

getline(cin, curChore);

getline(cin, curChore);

cnt = 0;

for (int index = 0; index < numChores; index++)

{

if (chores[index] == curChore)

{

chores[index] = chores[numChores - 1];

numChores--;

cnt++;

}

}

cout << "The number of chores deleted are " << cnt << endl;

break;

case 5:

cout << "Saving the chores list and exiting program!!" << endl;

outFile.open("input.bat");

for (int index = 0; index < numChores; index++)

{

outFile << chores[index] << endl;

}

cout << "Ending the program. " << endl;

exit(0);

break;

default:

cout << "There seems to be an error!! Run the program again.." << endl;

}

}

return 0;
