C doesn't initialize what? It initializes all used variables.


Not if they're on the stack. You should get a compiler warning
nowadays... but don't count on it!

Erm, C knows nothing about a "stack". However, it is true
that automatic variable are not necessarily initialized.
I should have stated that all statically allocated variables
are initialized. Thanks for the correction.

For completeness, dynamically allocated memory is not initialized either, unless allocated with calloc() (in which case, it is initialized to zeros) or realloc() (in which case, any added space is not initialized).
