WebAllocate a block of memory. We can also use a new operator to allocate a block (array) of a particular data type. For example. int *arr = new int [10] Here we have dynamically allocated memory for ten integers which also returns a pointer to the first element of the array. Hence, arr [0] is the first element and so on. Web1. Multi-dimensional arrays. C supports multidimensional arrays. The simplest form of the multidimensional array is the two-dimensional array. 2.
