Introduction to C and its operators

4.  These are the operators which are operators which are used to
perform mathematical calculation like add, subtract, multiply and
division.
Symbols Operation Example precedence
+ Addition A+B Lowest
- Subtraction A-b Lowest
* Multiplicati
on
A*b Highest
/ Division a/b Highest
% Module or
reminder
A%b Highest

5.  A relational operator is an operator which is
used to compose two values and result of
such operation is always true or false.

Operator operations
> Greater then
< Less then
>= Greater then equal to
< = Less then equal to
= = Equal to

6. Operator Operation
! Logical not or negative
&& Logical and or conjunction
” Logical or Disjunction

7.  General form :-
 Identifier = Expression
 for example : a =10 ;
 The other assignment operator are +=,-=,*=.

8.  A ) unary minus(-)
 B) increment and decrement operator (++ & --)
 C) address operator (&)
 D) value at address operator (*)
 E) NOT or Negative Operator (!)
 F) Size of operator [size of ( )]

9.  It can help the programmer in performing
simple conditional operations. It is also called as
ternary operator because it operate on these
values .

10. Operator Operations
<< Left shift of bits
>> Right shift of bit
~ Once compliment
& Bit wise and
~^ Bit wise x or
! Bit wise or

11.  It is basically used to group the selected
statement or expression. If a least of
expression are separated by comma (c)
language assume this list as a single
statement.
 for example : a=b, b=c,c=a+b;
