Two-dimensional array:

• A two-dimensional array is also referred as 2D arrays which can store multiple collections of data.

• It contains the rows and columns of elements.

• In two-dimensional array, normally the first subscript is called as row size and the second subscript is called as column size.

• All the rows will have equal number of columns. So, the arrangement of array elements looks like rectangular structure.

Declaration of two-dimensional array:

The two size declarators are needed to declare the two-dimensional array.

• First indicates the number of rows.

• Second indicates the number of columns.

The syntax to declare the two-dimensional array is given below:

datatype[,] arrName = new datatype[rows, columns];

Where,

• “datatype” indicates the data type of variable.

• “arrName” indicates the name of two-dimensional array variable.

• “rows” indicates the number of rows.

• “columns” indicates the number of columns.

Is this statement true or false? The subscript of the last element is always one less than the length of the array specified by the Length property.

The following statement save the value in which row of the 2 dimensional array names as "score"? scores[2][1] = 95; Select one: a. First Row b. Row 95 c. Third Row d. Second Row

True or FalseYou use the == operator to compare two array reference variables and determine whether the arrays are equal.
