Answer Posted / santhosh kumar sahukari
1.for static array we can find the no.of elements of its by using sizeof() operator and data type of that array.
2.we can find the no.of elements by its subscript in static array.
eg: int arr[10]
we can use sizeof(arr) to find the no.of elements it v l print 20,then we can divide it by 2 as size of int is 2.
2.subscript tells us it has 10 elements.
for dynamic array we cant use sizeof() operator.
we cant say dat how many elements it will have..it will be decided at runtime only.
