•  If double i = -20.5 then
                i++ = -20.5 // (if printed in same line)

              Unary Decrement (--) Operator
              The unary decrement (--) operator works only on one operand. The original value of the variable is decreased by 1 after
              the execution of this operator. It can work only on variables and identifiers which may either contain an integer literal
              or a real literal. The result of the decrement operator may be positive or negative.
              For examples:

              •  If int a = 20 and b = 4 then
                --a = 19
                b-- = 3 // (if printed in next line)
                Hence, the output is same as a = a - 1 or b = b -1.
              •  If int i = -20 then
                --i = -21
              •  If int i = -20.5 then
                i-- = -20.5 // (if printed in same line)
                i--=-19.5 // (if printed in next line)
                Program 2: To use all the arithmetic operators.



























              You will get the following output:



















              The unary increment and decrement operators are used in two forms which are prefix and postfix.
