manipulation and evaluation of data. (a) Arithmetic operators
Operators perform operations on variables
and values, forming expressions that Arithmetic operators include arithmetic
produce new values. Assignments then operations such as addition, subtraction,
store these resulting values into variables, multiplication, and division. Table 4.7
facilitating dynamic and efficient data shows arithmetic operators and their
handling within a program. meanings.

involve two operands and unary operators Note: Modulo division is the division
that involve only one operand. that gives the remainder after one
