A variable which is declared but is not initialized ever has an undefined value, but you can
                  assign it a value in later steps by using assignment operators.
                  Consider example 1, in which two variable ‘x’ and ‘y’ are declared. Variable ‘x’ stores a value
                  ‘20’ and variable ‘y’ stores a value ‘30’.

                  Now, when the program is executed, the memory location named as ‘x’ will hold a value ‘20’
                  and memory location named as ‘y’ will hold a value ‘30’.















                                           Coding fact

                    In 16  century, François Viète introduced the concept of presenting numbers
                          th
                    both known  and unknown  by letters in programming, which  are  nowadays

                    called as variables.



                  As you already know that a variable cannot be used unless a value is assigned to it. The value
                  of a variable can be initialized to ‘Null’, which is also a value. Variable which is defined with
                  the ‘Null’ value is a variable which is not initialized and also it does not hold any value, not
                  even ‘Null’. In some programming languages like Python, there is no command to declare

                  the variables. A variable is created at the moment, when you first assign a value to it.
