What I would do (besides not using C++ for such a trivial task ;) is read in a line (array of chars), check the line for being empty (the sentinel), and then parse the line as a number (using sscanf, I suppose). That also handles bogus input better, since your code won't handle malformed input well. In general, when I want a line of input from the user, I read a *line*, and parse it myself. You should also multiply degrees times M_PI/180, not the other way around.
