1.2.10 Precedence and Order of evalutaion

The table below summarizes the rules for precedence and associativity of all operators, including those which we have not yet discussed. Operators on the same line have the same precedence, rows are in order of decreasing precedence, so, for example, *, / and % all have the same precedence, which is higher than that of + and -.

Note that the precedence of the bitwise logical operators &, ^ and | falls below == and !=. This implies that bit-testing expressions like

if ((x & MASK) == 0) ...

must be fully parenthesized to give proper results.

1. () [] Left to right

2. ! ~ ++ -- - (type) * & Right to left

3. * / % Left to right

4. + - Left to right

5. << >> Left to right

6. < <= > >= Left to right

7. == != Left to right

8. & Left to right

9. ^ Left to right

10. | Left to right

11. && Left to right

12. || Left to right

13. ?: Right to left

14. = += == etc. Right to left

15. , Left to right
