What is an array variable how it is different from ordinary variable?

Array is different from ordinary variable because Array holds multiple values,whereas an ordinary variable hold a single value.It is true when the elements of the array are treated as individual entities,and when the variables such as an int.It is not generally right to distinguish between a variable and an array.

What is array and its type?

An array is a collection of one or more values of the same type. Each value is called an element of the array. The elements of the array share the same variable name but each element has its own unique index number (also known as a subscript). An array can be of any type, For example: int , float , char etc.

What is the two dimensional array?

A 2D array has a type such as int[][] or String[][], with two pairs of square brackets. … The elements of a 2D array are arranged in rows and columns, and the new operator for 2D arrays specifies both the number of rows and the number of columns. For example, int[][] A; A = new int[3][4];

How do you describe an array?
