                  Unary Decrement (--) Operator
                  The unary decrement operator (--) works on a single operand and decreases its value by 1. This operator is only
                  applicable to variables (or identifiers) with numeric data types, usually integers, though some languages may allow
                  it with floating-point numbers. Like the increment operator, the decrement operator has two forms:
                  •  Prefix Increment (++i): Decreases the value of i by 1 before using it in an expression.
                  •  Postfix Decrement (i--): Uses the current value of i in an expression and then decreases it by 1 afterward.
                         If i=-20      then,  = --i   = -21

                         If i= -20.5   then,  = i--   = -20.5
