The following table shows the precedence of associativity of the C operators.
Precedence
Operators
Associativity
High
( ), [ ]
→ Left to right
Unary
!, ~, ++, --, -, (type), *, &, sizeof
← Right to left
Multiplication,
division
*, /, %
→ Left to right
Addition,
subtraction
+, -
→ Left to right
Shift
<<, >>
→ Left to right
Relational
>, <, >=, <=
→ Left to right
Equality
==, !=
→ Left to right
Bit AND
&
→ Left to right
Bit XOR
^
→ Left to right
Bit OR
|
→ Left to right
Logical AND
&&
→ Left to right
Logical OR
||
→ Left to right
Conditional
?:
← Right to left
Assignment
=, +=, -=, *=, /=, <<=, >>=, &=, ^=, |=
← Right to left
Low
Order
,
→ Left to right
Note: Order of precedence is complicated. It is a good practice to use parenthesis
wherever the intention of the statement can be confusing for someone reading the
program, if not for the interpreter.
6.2.1 Cast operator
Data types are ranked as follows, with rank increasing from left to right:
Char < int < long < float < double …
In expressions with mixed data types, C will first convert all data to the same type as
that of the highest ranked data included in the expression, and then perform the
calculation. This is called implicit type conversion or type coercion.
This can become very complicated when unsigned types are involved. At the big
difference of BASIC that allows for one numeric type only, programming in C forces
to think carefully about minimum and maximum values that could occur, in order to
select the right data type and avoid unexpected results.
