Operator in C:-

Operator in C :- 1) Precedence and associativity of an operator only implemented if it is represented in INFIX notation.

Precedence decides which operation will be performed first.

Associativity decides the order of evaluation ( left to right or right to left) if more than one operator enjoy the same precedence.

The operator which requires three operands that are called ternary operator.

? : is a conditional ternary operator.

Associativity of a comma ( , ) operator is left to right.

# is a string forming operator that convert a non-string data to string and used only in preprocessor directives.

There is no operator in C to calculate the rise of a number.

Bitwise operators only work in integral type but do not work in float type.

Return value of relational and logical operators is 0 or 1.

x++, Here Microprocessor does both read and write operation.

1^st highest precedence:-

()

[] Left to Right

2nd highest precedence:-

—

! Right to Left

Size of()

Type

3rd highest precedence:-

/ Left to Right

4th highest precedence:-

– Left to Right

5th highest precedence:-

<< Left to Right

6th highest precedence:-

>= Left to Right

7th highest precedence:-

!= Left to Right

8^th highest precedence:-

Bitwise &

9^th highest precedence:-

^ Left to Right

10^th highest precedence:-

| Left to Right

11^th highest precedence:-

|| Left to Right

12^th highest precedence:-

&& (Logical AND) Left to Right

13^th highest precedence:-

? (conditional) Right to Left

14^th highest precedence:-

>>= Right to Left

<<=

15^th highest precedence:-

, Left to Right

It has no precedence and n
