Code in C++ please!

checkout.cpp is posted below

Start with the checkout.cpp file provided. You must make a class that works with the existing main() function that simulates checking out at a grocery store. You may assume fewer than 200 items will be checked out. Ensure that you class makes the provided main() output match the examples exactly. The add() function should add a checkout item to the items being bought, either increasing the amount by one if the item is already present or adding it to the list if it is new. You may directly compare strings when adding, thus if the string is different at all it can be treated as a new item. The checkout() function should return a list of all items and their quantities, along with a final additional line saying how many items were bought. Note that the item bought is the sum of the quantities, not the amount of different types of items on the list. The order that you display the items is not important (but the order the examples use is probably the easiest to do).

[Hint: A easy way to get numbers into string is to use the overloaded += operator for strings along with the int2str() function provided, for example: string x = ; x += int2str(2); x += x Apples; cout << x; // shows 2x Apples]

Example 1 (user input is bolded): apple banana apple !checkout

Receipt:

2x apple

1x banana

Total items: 3

Example 2 (user input is bolded): pasta milk pasta milk rice milk rice milk !checkout

Receipt:

2x pasta

4x milk

2x rice

Total items: 8

checkout.cpp code:

#include  #include  #include  #include  using namespace std; string int2str(int x); class GroceryList { // THIS NEEDS TO BE MADE }; int main() { GroceryList gl; string item; getline(cin, item); while(item != "!checkout") { gl.add(item); getline(cin, item); } int size; string* receipt = gl.checkout(size); // this should initialize size cout << " Receipt: "; int maxLen = 0; for(int i=0; i < size-1; i++) // list of items, but not total (last in array) { cout << receipt[i] << endl; if(static_cast(receipt[i].length()) > maxLen) { maxLen = receipt[i].length(); } } for(int i=0; i < maxLen; i++) { cout << "-"; } cout << endl; cout << receipt[size-1] << endl; // total number of items delete [] receipt; return 0; } string int2str(int x) { string reverse = ""; int pos = abs(x); while(pos > 0) { reverse += ('0'+pos%10); pos/=10; } if(reverse.length() == 0) { return "0"; } string result = ""; if(x < 0) { result += '-'; } for(int i=0; i < static_cast(reverse.length()); i++) { result += reverse[reverse.length()-1-i]; } return result; }
