correct...

It is not randomness but sound programming style!

Uninitialized global or static variables are defined as 0 by the
relevant C standards, and the 'uninitialized' version is preferred
because this way the variables don't take space in the image file:
only the total size is stored, and the loader initializes the memory
before giving control to the program.

It does not matter much for individual variables, but it does
for global arrays.
