Objective: Write a program in C$++$ that consolidates billing information from three businesses and outputs detailed reports.

Requirements:

Data Input $($see sample input files below the assignment description$)$:

$$ Read billing data from three external files $($e$.$g$.,$ CSV or JSON for extra credit$).$

$$ Each file should contain $10-15$ unique transactions with consistent customer IDs, transaction date, business name $($determined by the file source$),$ item name, and transaction amount.

$$ Business sources:

$$ file$1$ playForfun

$$ file$2$ goSport

$$ file$3$ shopAround

$$ Ensure no more than $2$ transactions per customer in any one file, but customers may appear in multiple files.

Data Structures:

$$ Store data in arrays of structs or class objects $($e$.$g$.,$ list$1,$ list$2,$ list$3).$

$$ Merge the arrays into a sorted list$4$ based on the merge aspect of merge sort. list$4$ is sorted$$ based on the name of customer id$.$

Output Requirements:

$$ Display and write list$4$ to an external file named after your last name.

$$ Create a customer summary report showing:

$$ Customer ID$,$ business name, items bought, total amount owed, and transaction count.

$$ Output to customerSummary file and screen.

$$ Create a business summary report showing:

$$ Total money owed and transaction count for each business.

$$ Output to$$ BusSummary file and screen.

$$

Modular Design:

$$ Use specialized functions and a header file.

$$ Store class$/$struct definitions in a header or separate file.

$$ Code should be organized with functions performing single operations.

$$ Validate that total owed by customers equals total payment to businesses.

Additional Requirements:

$$ Include screenshots and proper labeling..

$$ Overall code quality.
