Arithmetic operators are used to perform arithmetic operations on arithmetic operands, i. e., operands of integral as well as floating type. Recall that an integral type includes all forms of char and int types, whereas the floating-point types include the float, double and long double types. These operations include addition (+), subtraction (- ), multiplication (*), division (!), modulo arithmetic (%), increment (++), decrement (-- ), unary plus (+) and unary minus (- ). They can be grouped into three categories: unary operators, multiplicative operators and additive operators. The arithmetic operators are summarized in Table.
