Multidimensional array has elements along various dimensions. The elements of a multidimensional array are accessed using multiple indexes. For example a two dimensional array has elements in rows and columns as shown below:
multiarray  = 

Two indexes are required to access the elements of this array.
multiarray[1][1] is the element in the 1st row and 1st column which is 200
multiarray[1][2] is the element in the 1st row and 2nd column which is 300
multiarray[1][3] is the element in the 1st row and 3rd column which is 500
multiarray[2][1] is the element in the 2nd row and 1st column which is 130
multiarray[2][2] is the element in the 2nd row and 2nd column which is 230
and so on....
A multidimensional array is declared using the syntax
variabletype arrayname[dimension1limit][dimension2limit]....[dimensionnlimit];
multiarray in the above example is declared as:
mutiarray[3][3];
