Question

What values are automatically assigned to those array elements which are not explicitly initialized?

Answer 1

Answer:

In C, 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.

For example, following program prints:

Value of g = 0

Value of sg = 0

Value of s = 0
