Question
Using this data file (salesdata.txt), complete the following tasks:
We will use the following arrays for this class project.
names as string
empID as C-string with length of 5 ( hint declare as char array )
wages as double
unitsSold as integer
Write a function, fillArray, that fills the elements of each array from a data file, salesdata.txt, located in C:classdata (create a folder C:classdata on your computer). Hint: Examine the format of the data file before designing your solution.
Write a function, displayTable, that displays the elements of the arrays in a tabular format
Write a function, searchID, that searches for an empID and returns the index. If the empID is not found return -1. Make sure to accept a reference integer parameter.
Write a function, displayEmployee, that accepts the index of the searchID result then displays all of the information about a single employee, in form layout, based on the index. If the index is -1 then display a friendly error message like “Error: Employee not found”
Write a function, changeUnitSold, that accepts the index of the searchID result then changes the value of unitsSold of a single employee based on the index of the empID. If index is -1 then change nothing
Write a function, changeWage, that accepts the index of the searchID result then changes the value of wages of a single employee based on the index of the empID. If index is -1 then change nothing.
Write a function, sortByEmpID, that organizes the arrays in ascending order based on empID values. (Use the bubble sort method)
Write a function, searchName, that searches for all occurrences of a name that begins with a specific letter. Store the subscripts in an array called searchResults that stores up to 20 elements then display the list on the screen.
Write a main function that calls fillArray then displays a menu that looks like this. The highlighted text is the user input
Call functions based on user’s menu selection. Allow the user to run the program and display the menu until choice G is selected that terminates the program.
