I'm building a program that reads in states(strings) and tax rates(floats) from an input file and stores it into a vector of objects of a class called TaxBill. The class has 3 data members called stateName, taxBill, and index. There are also set()/get() functions for each respective data member.
Now, I don't have a question regarding my code (it is incomplete, but I'm still working on it). I am getting this error every time I try to compile it.

I couldn't figure out what was wrong so I created a new project and imported my cpp and header files and I got the same error. I then created a new project using a different .NET framework(4.5.1, I was using 4.6.2 previously). Same error occurred. So then I tried making a project using .NET 4.5.1 and selecting "Empty Project" in the project creation menu. I got the same error.
So then I made a simple "Hello World" program to see if there wasn't something wrong with my compiler. The program ran just fine. Here is the output from the .log in the Debug folder.

Can anyone tell me what's going on or what I did wrong? My code is below.
