error C2181: illegal else without matching if

[instruisto]

My assignment is to write a simple calculator. I keep getting

Error 1 error C2181: illegal else without matching if c:\users\sx\dropbox\c++ intro folder\calculatorsim\calculatorsim\blankenshippaulcalculatorsim.cpp 44 1 CalculatorSim

and

Error 2 error C2181: illegal else without matching if c:\users\sx\dropbox\c++ intro folder\calculatorsim\calculatorsim\blankenshippaulcalculatorsim.cpp 48 1 CalculatorSim

I checked for semi-colons after the "if" lines read several forum posts and looked at a couple of books but I don't see where I am going wrong.

It compiles and runs fine for me.

Thanks for checking it, Peter. Which compiler did you use? I used MSVS Express 2012.

[Peter87]

GCC 4.7.1

Once I actually compiled and ran the program it worked for me. I kept getting those errors while working on the program. MSVS is more complicated than C++.

[greenleaf800073]

GNU GCC compiler

Thanks Peter and Greenleaf; I am going to check that out. Things have changed a bit since Fortran 77.
