            Performing Operations on Variables

            Variable is a storage area, which defines the size, layout, range set of operations to be performed
            on variable.
            Once you declare the data types, you will learn to perform the operations on the data types.

               Operator: It is a symbol which operates on a value assigned to a variable. Example: +,-, *, \.
               Operand: It is a value on which the operator performed operation.

            Arithmetic Operators

            Arithmetic operation combines two or more numeric expressions by using the arithmetic operators.
            The arithmetic operators perform operations such as: addition, subtraction, multiplication, division,
            and modulus. In the table given below, we are taking, value of variable a= 10, and of b=30.

               Operation        Symbol                        Description                         Example

             Addition               +       Adds one operand to the other                     a+b= 40

             Subtraction            -       Subtracts second operand from the first           a-b= 20

             Multiplication         *       Multiplies one operand by the second              a*b=  300


             Division               /       Divides first operand by the second               b/a= 3

             Modulus               %        Divides  the  first  operand  by  the  second,  and  b%a= 0
                                            returns the remainder

             Increment             ++       Increases the integer value by 1                  a++ = 11

             Decrement             --       Decreases the integer value by 1                  b-- = 29


            Assignment operators

            An assignment operator assigns a new value to a variable.
            In the table given below, we are taking, value of variable a=10, and b=30.


                  Operator         Symbol                Description                        Example

             Simple assignment        =      Assigns value to the left operand    c = a + b (c = 10 + 30)
             operator                        from right operand                   will assign the value of c to
                                                                                  a + b (c = 40)
