No, but you may be a great "Hello world in C" writer. People can be insanely fast at solving Rubik's 3x3x3, but that doesn't imply they are good at puzzles in general or even at a 4x4x4.

[by the way, "Hello World" in C is a surprising amount of work. For example, version 2.9 is over 270 lines, and saw over 40 revisions for the main file (http://git.savannah.gnu.org/cgit/hello.git/log/src/hello.c)]
