Programing lanugaue is C++
Purpose of code:
Plan and code a menu-driven modular program utilizing an array
An input file has an unknown number of numeric values(could beempty too).Read the numbers from the input fileand store evennumbers in one arrayand odd numbers in another array.Create menuoptions to
Display count of even numbers, count of odd numbersand the sumvalues in each array
Determine the average of each array
Determine the median of each array
Sort each array in ascending order(use bubble sort) and outputresults to a file
Display X number of the highest values(for example, 3 highestvalues) in each array.Ask a user for the number of the highestvalues
Display X number of the lowest values(for example, 7 lowest values)in each array.Ask a user for the number of the lowest values
A user should be able to run many as many times as a userwants
Notes :
Clearly label all output
Use switch statement to implement the menu
Watch put for array boundaries.C would not do it for you.
You only need to create one function to determine the average.Justcall it twice to determine the average of each array.The sameapplies to the rest of the menu options.
A user should be able to run the menu as many times as a userwants
Thoroughly test your program.Your grade partially depends on thequality of your test data.
Must comply with the posted guidelinesand standards
Well document your code(comments)
Question: Is it possible to rewirte this code with the samepurpose but without the Vector function? Is is possible to make asmall edits or will I have to rewrite the whol code? Can someoneshow me how rewrite the code without a vector function?
