malloc(0) does not return a non-NULL under every implementation. An implementation is free to behave in a manner it find suitable, if the allocation size requested is zero. Theimplmentation may choose any of the following actions:* A null pointer is returned.* The behavior is same as if a space of non-zero size was requested. In this case, the usage of return value yields to undefined-behavior.
