Initializing Arrays

C# provides simple and straightforward ways to initialize
arrays at declaration time by enclosing the initial values
in curly braces ({}). The following examples show different
ways to initialize different kinds of arrays.

Note If you do not initialize an array at the time of
declaration, the array members are automatically initialized
to the default initial value for the array type. Also, if
you declare the array as a field of a type, it will be set
to the default value null when you instantiate the type.

Single-Dimensional Array

int[] numbers = new int[5] {1, 2, 3, 4, 5};
string[] names = new string[3] {"Matt", "Joanne", "Robert"};

You can omit the size of the array, like this:

int[] numbers = new int[] {1, 2, 3, 4, 5};
string[] names = new string[] {"Matt", "Joanne", "Robert"};

You can also omit the new operator if an initializer is
provided, like this:

int[] numbers = {1, 2, 3, 4, 5};
string[] names = {"Matt", "Joanne", "Robert"};

Multidimensional Array

int[,] numbers = new int[3, 2] { {1, 2}, {3, 4}, {5, 6} };
string[,] siblings = new string[2, 2] { {"Mike","Amy"},
{"Mary","Albert"} };

You can omit the size of the array, like this:

int[,] numbers = new int[,] { {1, 2}, {3, 4}, {5, 6} };
string[,] siblings = new string[,] { {"Mike","Amy"},
{"Mary","Albert"} };

You can also omit the new operator if an initializer is
provided, like this:

int[,] numbers = { {1, 2}, {3, 4}, {5, 6} };
string[,] siblings = { {"Mike", "Amy"}, {"Mary", "Albert"} };

Jagged Array (Array-of-Arrays)

You can initialize jagged arrays like this example:

int[][] numbers = new int[2][] { new int[] {2,3,4}, new
int[] {5,6,7,8,9} };

You can also omit the size of the first array, like this:

int[][] numbers = new int[][] { new int[] {2,3,4}, new int[]
{5,6,7,8,9} };

-or-

int[][] numbers = { new int[] {2,3,4}, new int[] {5,6,7,8,9} };

Notice that there is no initialization syntax for the
elements of a jagged array.
Accessing Array Members

Accessing array members is straightforward and similar to
how you access array members in C/C++. For example, the
following code creates an array called numbers and then
assigns a 5 to the fifth element of the array:

int[] numbers = {10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0};
numbers[4] = 5;

The following code declares a multidimensional array and
assigns 5 to the member located at [1, 1]:

int[,] numbers = { {1, 2}, {3, 4}, {5, 6}, {7, 8}, {9, 10} };
numbers[1, 1] = 5;

The following is a declaration of a single-dimension jagged
array that contains two elements. The first element is an
array of two integers, and the second is an array of three
integers:

int[][] numbers = new int[][] { new int[] {1, 2}, new int[]
{3, 4, 5}
};

The following statements assign 58 to the first element of
the first array and 667 to the second element of the second
array:

numbers[0][0] = 58;
numbers[1][1] = 667;

Write a program which has a function and that function should take 2 or 3 or any number of strings and it should return the largest common prefix of all those strings. If there is no common prefix it should return an empty string. for eg:- INPUT OUTPUT glo {glory,glorious,glod} gl {glad,glow} {calendar,phone} empty string
