Two dimensional arrays, Basic Computer Science

Two dimensional Arrays:  A two-dimensional array is like a table, with a defined number of rows, where each row has a defined number of columns. In some instances we need to  have such an array of arrays. It will have two dimensions and data is represented in the form of rows and columns.  

Type name [elements] [elements]; 

For example int a [3] [3]; /* lets one dimension depict location and other dimension represent sales in a day or a week or a month*/
