static promenne v codevisionu

[Miroslav Šinko]

To nie je pravda, dokonca norma ANSI C hovori o hodnotach
neinicializovanych premennych:

10 If an object that has automatic storage duration is not initialized
explicitly, its value is
indeterminate. If an object that has static storage duration is not
initialized explicitly,
then:
— if it has pointer type, it is initialized to a null pointer;
— if it has arithmetic type, it is initialized to (positive or unsigned) zero;
— if it is an aggregate, every member is initialized (recursively)
according to these rules;
— if it is a union, the first named member is initialized
(recursively) according to these
rules.
