WebTwo-dimensional Arrays. The simplest form of multidimensional array is the two-dimensional array. A two-dimensional array is, in essence, a list of one-dimensional arrays. To declare a two-dimensional integer array of size [x][y], you would write something as follows −. type arrayName [ x ][ y ]; WebThe use of a pointer to a pointer in conjunction with dynamic memory allocation is advantageous over a static matrix as it allows the allocation of a two-dimensional array of desired size and shape, avoiding wastage of memory. Note that when a pointer to a pointer is declared, the memory is allocated only for the pointer variable.
