Operators

The operators are used to control/operate the various types of expressions within any program of the 'C' language.

In 'C' language,there are five types of operators:

Arithmetical Operators

1. "+" : for addition
2. "-" : for subtraction
3. "*" : for multiplication
4. "/" : for division
5. "%": for modulation(to obtain the remainder).

Ex: 5/2 = 2.5 , 6/2 = 3 , 5%2 = 1 , 6%2 = 0.

Logical Operators

1. "&&" : AND(Double Ampersand)
2. "||" : OR(Double Pipe)
3. "!" : NOT(Exclamation).

Relational Operators

1. ">" : is greater than
2. ">=" : is greater than or equal to
3. "<" : is less than
4. "<=" : is less than or equal to
5. "==" : is equal to
6. "!=" : is not equal to.

Assignmental Operators

    "=" : equals or equal to.
Ex: a = 5 ('5' is assigned to variable 'a') , while in a == 5 ('a' is compared with '5').

NOTE:Logical operators are never used independently , thy are used in combination with Relational Operators.

Short-Hand Operators

These operators are very useful as they decrease the time consumption.That's why they are known as Short-Hand Operators.

1. "++" : incremental operator(increase by '1')
2. "--" : decremental operator(decrease by '1')
3. "+=" : increment by '1' or any real value
4. "-=" : decrement by '1' or any real value
5. "*=" : multiply by any value
6. "/=" : divide by any value.

Ex: 1. k = k + 1  OR  k++

      2. k = k - 1  OR k--

      3. k = k + 2  OR k+=2

      4. k = k - 2  OR k-=2

      5. k = k * 3  OR k*=3
      6. k = k / 3  OR k/=3.
