Yes.

Did you declare the variable X before using it?  With the proper type,
which is "X *" (since "new X" returns pointer-to-X)?  What you have
written is an assignment statement, not a declaration.  Also, note that
one major difference between C++ and C is that a class declaration in
C++ implicitly does a typedef as well, which means using the same name
for a variable and a type is a bad idea.  Try making it "X *Y = new X;".
