This assignment involves manipulating "structured" data, similar to what might be analyzed with a spreadsheet. Spreadsheet rows are typically indexed with an integer, and the columns are assigned names. An array of structs is accessed similarly.

Part $1$

Every week a company generates a text file containing one line per salesperson. The lines contain the salesperson's first name, last name, and their total weekly sales. These three fields are separated by "white space" $($blanks and$/$or tab characters$).$

You are responsible for running your code through the auto$-$grader using the link at the bottom of this page.

Add C$++$ code to the solution$()$ function in code.cpp and to the main$()$ function in main.cpp that:

$1.$ Defines constexpr int NUM$\_$SALESPEOPLE to store the current number of employees.

$2.$ Defines a struct containing a first name field $($a std::string$),$ a last name field $($also a std::string$),$ and a weekly sales data field $($a double$).$ Note that this is a different struct that is already defined in code.hpp$.$ The struct PaymentInfo will be used in Part $2.$

$3.$ Declares an std::vector of these structs with NUM$\_$SALESPEOPLE entries.

$4.[$Done for you in main.cpp$]$ Opens the stream text file named sales$\_$data.txt$.$ If the file cannot be opened, then a descriptive error message is displayed, and execution terminates abnormally.

$5.$ Reads each line of the sales$\_$data.txt file into a separate entry of the array.

$6.$ Compute the combined weekly sales as well as the maximum individual sales amount while reading the sales$\_$data.txt file.

$7.$ Displays the combined and maximum weekly sales on the console:

Combined weekly sales is $$20892\mathrm{.}6$

Maximum weekly sales is $$4523\mathrm{.}11$

Be sure to read comments in the code providing guidance on what needs to be added. CMakeLists.txt takes care of copying sales$\_$data.txt from the source code directory to the build subdirectory so that you don't have to do that manually. Look over CMakeLists.txt$,$ which is mostly readable.

Part $2$

Add the following functionality to the first part: Use the array to compute the weekly payment to each salesperson and display it on the console. The payment is a $10\%$ commission on their sales amount. In addition, the salespeople with the maximum weekly sales $($there could be more than one$)$ receive a $$200$ bonus. Payments should be rounded to the nearest dollar:

Combined weekly sales is $$20892\mathrm{.}6$

Maximum weekly sales is $$4523\mathrm{.}11$

Sales staff payments are:

Justin Blake $$323$

Rachel Davide $$413$

Colin Forth $$652$

Diana Ince $$310$

Carol Marsh $$98$

Emma McNish $$104$

Phil Morgan $$0$

Sue Parsons $$172$

Boris Pullman $$210$

Dan Terry $$6$

Tab $(\text{'}\backslash$t$\text{'})$ characters are used to line up the columns.
