WebApr 18, 2003 · In summary, there is no reason ever to return null from an array-valued method instead of returning a zero-length array. This idiom is likely a holdover from the C programming language, in which array lengths are returned separately from actual arrays. In C, there is no advantage to allocating an array if zero is returned as the length.

WebTo ensure data locality, the C++ object contains as last member an array of size 0. Later, when a new clause is needed, a placement new is used. The memory allocated for that object will be equal to the size of the object + the number of elements in the array. That way, we have all data togheter. Webarray [0] refers to the 0 th row of the block array. While array [0].length refers to the columns associated with 0 th row i.e. 70. Therefore, the answer would be 70. array.length: The length property is used to find the array length. array [0].length: The number of columns on row 0. array [1].length: The number of columns on row 1.
