For(int x = 4; x > 0; --x) Console.Write(nums[x]);

For(int x = 3; x >= 0; --x) Console.Write(nums[x]);

For(int x = 3; x > 0; --x) Console.Write(nums[x]);

for(int x = 4; x >= 0; --x) Console.Write(nums[x]);

Array.Sort(nums);

Array.Reverse(nums);

Array.Sort(nums); Array.Reverse(nums);

Array.Reverse(nums); Array.Sort(nums);

Both methods take a single argument that must be an array

Both methods belong to the System.Array class.

Th e array that each method uses must be in ascending order.

They both operate on arrays made up of simple data types but not class objects.

An error message is displayed

A zero is returned

The value false is returned

A negative value is returned

Int[8, 5] num = new int[ , ];

Int [8][5] num = new int[];

Int [ , ] num = new int[5, 8];

int [ , ] num = new int[8, 5];

array items are in ascending order

The array holds duplicate values and you want to find them all

You want to fi nd an exact match for a value

Array items are not numeric
