Detailed explanation-1: -Hence, if we simply divide the size of the array by the size acquired by each element of the same, we can get the total number of elements present in the array.
Detailed explanation-2: -An array is a structure that contains an ordered collection of data elements in which each element can be referenced by its index value in the collection. The cardinality of an array is the number of elements in the array. All elements in an array have the same data type.
Detailed explanation-3: -2. What is the index number of the last element of an array with 9 elements? Explanation: Because the first element always starts at 0. So it is on 8 position.
Detailed explanation-4: -Each item in an array is called an element, and each element is accessed by its numerical index. As shown in the preceding illustration, numbering begins with 0. The 9th element, for example, would therefore be accessed at index 8.
