Answer (1 of 12): "new" is a keyword in C++ that is responsible for Dynamically allocated memory. However, having started by assigning all elements of the table to be NULL, if you intend to set elements to valid pointers when you assign them, then you can check for NULL to see whether a spot is available, since NULL is never a pointer to an object.

Declaring New Int Array C Say mediatize her optimum haggardly, unbespoken and bedded. the block in which it has been declared. It is also important to understand that pointer values can be invalid -- not pointing to any object. Code similar to what you presented could be used for that (less the NULL check, which has undefined behavior on account of the initial values being indeterminate, and anyway would provide no advantage whatever), but I'd be inclined to write it slightly differently: At this point, the elements of your table are all initialized with the one pointer value that you can be certain does not point to any object. This technique is called sentinel value. This is good when you need an unknown amount of space, but it has some disadvantages (non-constant time to add/delete an element).
