I have what looks to me like perfectly good code, but still get your typical
cryptic error message...

Anyone have any ideas?

Errors:
vector.cpp: In method `shape::shape(int, int, int)':
vector.cpp:134: parse error before `;'
vector.cpp:137: warning: ANSI C++ forbids declaration `stype' with no type
or storage class
