This is my very first introduction to C++ and I am stuck with a very simple mini-calculator project. I cannot figure out what the errors are that the compiler is showing. I have shown my written code and the compiler messages below that. I am receiving syntax errors on the 'outfile' lines where I was asked to format the output. I would appreciate any help given. Thank you, thank you!!!
