I really need help on this programming problem that am doing in Visual Studio 2019 in C++

Submit your .cpp file as well as the input file, the output file, and the screen shot of all the files tiled next to each other here!

Instructions:

Write a menu driven program that has three options:

Option 1: Write a function that calculates the tax for an iphone. The price and the tax rate should be asked from the user. Input validation: Do not accept negative numbers or string.

Option 2:

1- Create an input file with several numbers.

2- Read the numbers from your file into the program utilizing a for loop.

3- Multiply the numbers utilizing a for loop.

4- Write the result into a file.

Option 3: Exit the program

At the end of the program ask the user if they want to repeat the program or not, utilizing a do-while loop. ( If the user says yes to repeat, your program should start over again automatically)

What to submit: Submit the input file you have created, the output file that was created by your program, your .cpp file and the screen shot of the output( be sure all the files are tiled next to each other before taking the screen shot).

Let me know if you have any questions!
