-The first column: transaction number

-The second column is number of model A units sold,

-The third column is the price of model A unit

2603 14 1.99 14 2.19

2604 9 1.99 11 2.19

2605 13 1.99 16 2.19

2606 11 1.99 10 2.19

2607 7 1.99 12 2.19

Task2: Ending day sale report:

-At the end of the day, users will run task 2 to calculate subtotal of sale during the day.

* open and read the file Sale_yyyy_mm_dd.txt that is created from the task 1.

* For each line: calculate the money of model A sold and the money of model B sold on each sale transaction, thenadd up to have sum of number model A units sold, sum of money model A sold, sum of number model B units sold,sum of money model B sold and total money sold both model sold during the day

* display the report of the day on the screen and write one line to the output file to file SaleInMonth_yyyy_mm.txt

For example: on the day 06/26/2016, there are 10 sale transaction in above file Sale_2016_06_26.txt

The output of the Day Sale Report on the screen a below:

216.91 (total money sold model A whole day)= moneyA of transaction1 + moneyA of transaction 2+ . +monye of transaction 10

293.46 (total money sold model B whole day)

= moneyB of transaction1 + moneyB of transaction 2+ . +money of transaction 10

This is an example of file SaleInDay_yyyy_mm_dd.txt

That has 10 sale transactions during the day.

You can use it for testing the task 2

The bold line is result from the example

moneyA of each transaction = number of modelA units (2nd column) * price of unit A (3rd column)

moneyB of each transaction = number of modelB units (4th column) * price of unit B (5th column)

109 (total A units sold in whole day) = sum of 2nd column

234 (total B units sold in whole day) = sum of 4th column

510.37 (total money sold in the day)

= total money sold model A whole day + total money sold model B whole day

These above information of each day sold will be saved on one line in the file SaleInMonth_2016_06.txt with 5information that are separated by a tab \t as below

*The 1st column is the day of the month

*The 2nd column is the number of model A sold on each day

*The 3rd column is the money sold model A on each day

*The 4thcolumn is the number of model B sold on each day

3.Task Ending Month Sale report:

-At the end of each month, based on the information that was stored in the files from task2 (file

SaleInMonth_yyyy_mm.txt), the users will calculate the subtotal for the month, print out the report on the screenand write one line to the file SaleInYear_yyyy.txt

For example:

On June 2016, there is 30 sale days, each line contains the information of each day in file SaleInMonth_2016_06.txt

*The output on the screen as follows:

This is an example of file SaleInMonth_yyyy_mm.txt

That has 30 sale transactions during the month.

You can use it for testing the task 3

The bold line is result from the example

2651 (total model A units sold in month) = subtotal of 2nd column

5299.29 (total money sold model A in month) = subtotal of 3rd column

3219 (total model B units sold in month) = subtoal of 4th column

7051.61 (total money sold model B in month) = subtotal of the last column

12350.90 = money sold model A in month + money sold model B in month = 5288.29 + 7051.61

*The file name of output file is SaleInYear_yyyy.txt where yyyy is current year

For example, at the end of the year 2016, the file SaleInYear_2016.txt will have 12 lines. Each month, the abovetask writes one line

There are 12 lines of 12 months

-The first column is the month

-The second column is number of model A sold in one month

-The third column is the money of model A sold in one month

-The fourth column is number of model B sold in one month

-The last column is the money of model B sold in one month

Between these columns, there is one tab \t

Task Ending Year sale report:

-At the end of year, based on the information of file SaleInYear_2016.txt to provide the report on the screeen asbelow:

31186 (total model A units sold in year) = subtotal of 2nd column

62083.94 (total money sold model A in year) = subtotal of 3rd column

35086 (total model B units sold in year) = subtotal of 4thcolumn

62083.94 (total money sold model B in year) = subtotal of last column

138924.28 (total money sold both models in year)

= money sold model A in year + money solde model B in year = 62083.94 + 76840.34

This is an example of file SaleInMonth_yyyy.txt

That has 12 lines for 12 months

You can use it for testing the task 4

WHAT WE NEED TO KNOW TO DO THE PROGRAM

To do this project you should review the following:

-How to open file to read, how to read the file

-How to open file to append, how to write one line to the text file

-How to get the current date read the topic HOW TO GET CURRENT DATE from the page Learn From

Questions on eCampus

#include

//date will be in the format: 06/26/16

char currentDate[10];

_strdate(currentDate);

string date(currentDate);

cour << date: << date << endl;

-How to get a substring from a string: read the topic HOW TO GET A SUBSTRING FROM A STRING from the

page Learn From Questions on eCampus

string date = 06/26/16;

//temp1 = 06/26/

String temp1 = date.substr(index start, number of character in substring) = date.substr(0,6)

//temp2 = 16

String temp2 = date.substr(index start) = date.substr(6); //from index6 to the end

-How to concatenate string:

string year = 20 + temp2; // year = 2016

string newDate = temp1 + 20 + temp2; // newDate = 06/26/2016

-How to find a character in a string: using find function

Example: string line = 01 2777 5526.23 3223 7058.37;

There is a tab \t between these numbers

int pos = line.find(\t); // pos = 2 the first tab in line

Then you can extract the first information:

string first = line.substr(0,2); // first = 01

line = line.substr(pos+1); //line = 2777 5526.23 3223 7058.37;

keep doing the same way we can extract each number and assign to different variables to be used

-How to convert a numeric string to a number. Read the topic Convert a numeric string to a number Using

atoi or atof from the page Learn From Questions on eCampus

String temp1 = 34;

String temp2 = 22.75;

Int num = stoi(temp1); // num = 34

double num2 = stof(temp2); // num2 = 22.75
