C++ Can someone help me get my program to work correctly? I'm having an issue with it displaying the file (last entry twice), finding certain item numbers, and the change when you give too little of the amount when paying.

------------------------------------------------

this is the input file named stock.txt:

1234 Stockings 12.39 2865 Pajamas 17.99 4020 Dress 23.00 3640 Sweater 20.50 5109 Shorts 56.99 4930 TV 88.20 6600 ToothBrush 94.55 5020 AluminumPan 16.79 2336 Pencils 4.55

this is my code:

#include

//Declare files

//Formula variables

int counter = 0;

float totalCost = 0.0;

float totalForAll = 0.0;

float taxForAll = 0.0;

float change = 0.0;

//Variables that are received from the text file "Stocks"

int partNumber = 0;

const int SIZE = 81;

char description[SIZE];

float price = 0.0;

//Format accordingly
