An operator is a symbol which helps the user to command the computer to do a certain mathematical or logical manipulations. Operators are used in C language program to operate on data and variables. C has a rich set of operators which can be classified as

When a division is performed the remainder of the operation is given by modulus operator. The modulus operator is denoted in c by symbol %. Say for instance we have two integer values x and y and then the operation x % y called as x modulus y gives the result as (x- (x / y) * y). Say if x=18 and y =5 the x % y gives value as (18- (18 / 5) * 5) which gives (18-15) which results in 3 in other words the remainder of the division operation.

The ++ operator is called the increment operator. When the operator is placed *before *the variable (++var), the variable is incremented by 1 before it is used in the expression. When the operator is placed *after *the variable (var++), the expression is evaluated, and then the variable is incremented by 1.

Boolean operators AND, OR, and NOT are used to manipulate logical statements. Boolean operators are the core operators used in digital control systems as well as computer systems. AND and OR are binary operators, while NOT is a unary operator. Let *A *and *B *be two logical statements or variables representing logical statements. If a logical statement is *true *it may be assigned the value 1, and if a logical statement is *false *it may be assigned the value 0. Table gives details of the three operators AND, OR, and NOT.

When number of operators occurs in an expression the operator which is to be evaluated first is judged by applying priority of operators. The arithmetic operators available in C are

+ used for Addition

- used for Subtraction

* used for Multiplication

/ used for Division

All the objects that are stored in a computer are ultimately converted into binary numbers which are sequences of 0s and 1s. Each digit in a binary number is stored on one bit of the computer memory. A *bit *is defined as the smallest unit of memory in a computer. In fact, computer manipulates a number by manipulating the bits on which the number is stored. In control systems also we often need to use operators to manipulate bits.

The sizeof operator is another method to determine the storage requirements of any data type of variable during the execution of a program. For example, we can use the expression.

Arithmetic operators may be combined with the assignment operator to obtain composite assignment operators. An arithmetic operator is written first followed by the assignment operator but not vice versa. **In all the composite operators there should not be any blank space between the symbols. **For instance, in+= if we give space between+ and= (suchas+ =),it may result in an error.

The C language provides four relational and two equality operators for comparing the values of expressions. The **relational operators **are *less than (*<), *greater than *(>), *less than or equal to (*<=) and *greater than or equal to *(>= ). The **equality operators **are *equal to *(==) and *not equal to ( ! *=). These operators are binary infix operators, i. e., they are used in the form *a op **b, *where *a *and bare operands (constants, variables or expressions) and *op *is a relational or an equality operator. Table summarizes these operators.

There are five arithmetic operators, +, -, *, *I, *and %, which respectively represent the processes of addition, subtraction, multiplication, division, and modulus. The modulus operator (%) gives the remainder when one integer is divided by another integer. All of the five operators have been described with examples of codes in Table.
