Syntax: public int GetUpperBound (int dimension); Here, dimension is a zero-based dimension of the array whose upper bound needs to be determined. Searches for the specified object and returns the index of the last occurrence within the range of elements in the one-dimensional Array that contains the specified number of elements and ends at the specified index. LastIndexOf(T[], T) Searches for the specified object and returns the index of the last occurrence within the entire Array.

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.

Given a sorted array of integers, find index of first or last occurrence of a given number. If the element is not found in the array, report that as well In normal 

The positioning of array starts from subscript 0. Well subscript is also known as indices. It is the value in big brackets []. To find index number, u can use the formula (n-1). Here n=29 so (n-1)=28. Hence the index of the 29th element is 28. # Hope it helps. # Smritu.
