Default values in array

Question

What are default values for arrays like this:

char c[20];

?

BTW, Are there any?

Answer 1

Undefined or in less technical language - random.

Your compiler (at least in debug mode) may set it to a particular value for testing.

And of course from a strict Copenhagen interpretation of quantum theory the value it does have is both indeterminate (used in it's correct sense) until you collapse the wavefunction by measuring it.
