Question

Differentiate between the following:

Ordinary variable and array variable.

Answer 1

S. No.	Ordinary variable	Array variable
1.	It refers to a single variable that can only contain one value.	A collection of variables with the same data type can have various values.
2.	No index notation is used for ordinary variables.	In addition to the variable name, the index value must be given in square brackets.
3.	Because it relates to a single variable, the .length method cannot be applied.	The .length method can be used to ascertain the array's size.
