In VB, . . . . . . . . is used to enter the more then one value in a single variable having different data types.

The correct answer is C. array.

An array is a data structure that stores a collection of elements of the same data type. The elements of an array are accessed using an index, which is a number that indicates the position of the element in the array.

In VB, an array can be declared using the Dim statement. The syntax for declaring an array is as follows:

Dim arrayName(size) As dataType

where:

• arrayName is the name of the array.
• size is the number of elements in the array.
• dataType is the data type of the elements in the array.

For example, the following statement declares an array named myArray that can store 10 elements of type Integer:

Dim myArray(10) As Integer

Once an array has been declared, it can be initialized using the New keyword. The syntax for initializing an array is as follows:

arrayName = New dataType()

For example, the following statement initializes the array myArray with the values 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10:

myArray = New Integer() {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

The elements of an array can be accessed using the index. The index of the first element in an array is 0, the index of the second element is 1, and so on.

For example, the following statement assigns the value 10 to the third element of the array myArray:

myArray(2) = 10

The following statement prints the value of the first element of the array myArray:

Print myArray(0)

Arrays are a powerful data structure that can be used to store and manipulate large amounts of data. They are often used in computer programming to store data that is related to each other.
