Hi,
please, initialize "i" to 0.
Non-initialized variable store garbage,
not zeroes.
It probably does not look very well, but otherwise correct:
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.
