Priority of Operators:

Priority	Operators	Description
1^st	* / %	multiplication. division. modular division
2^nd	+ -	addition, subtraction
3^rd	=	assignment

Associativity of Operators:

Operator	Description	Associativity
( )	Parentheses or function call	left to right
[ ]	Brackets or array subscript	left to right
.	Dot or Member selection operator	left to right
- >	Arrow operator	left to right
+ + - -	Postfix increment/decrement	left to right
+ + - -	Prefix increment/decrement	right to left
+ -	Unary plus and minus	right to left
! ~	not operator and bitwise complement	right to left
(type)	type cast	right to left
*	Indirecton or dereference operator	right to left
&	Address of operator	right to left
sizeof	Determine size in bytes	right to left
* / %	Multiplication, division and modulus	left to right
+ -	Addition and Subtraction	left to right
<< >>	Bitwise left shift and right shift	left to right
< <=	relational less than/less than equal to	left to right
> >=	relational greater than/greater than equal or equal to	left to right
== !=	Relation equal to or not equal to	left to right
&&	Bitwise AND	left to right
^	Bitwise exclusive OR	left to right
\|	Bitwise inclusive	left to right
&&	Logical AND	left to right
\| \|	Logical OR	left to right
? :	Ternary operator	right to left
=	Assignment operator	right to left
+= -=	Addition/ Subtraction assignment	right to left
*= /=	Multiplication/ division assignment	right to left
%= &=	Modulus and Bitwise assignment	right to left
^= \|=	Bitwise exclusive/inclusive OR assignment	right to left
<<= >>=		right to left
,	comma operator	left to right

When an expression contains two operators of equal priority then it is settled using associativity of operators.
It is of two types:
Left to Right or Right to Left.
The above table shows the associativity of various operators.
