okay so im working on a C++ lab and i need to follow this flow chart. im working in visual studio 2013 and i encounter a problem where it claims the variable "triangle" isnt being defined. when i type in "t" for triangle calculations. im not sure what this means or how to fix it and was hoping for some guidence.

the code so far.
