| Synopsis: | Expressions which either mix operators from the set >, >=, <, <=, ==, !=, with operators from the set <<, >>, ^, &, |, &&, || or which use two or more distinct operators from the latter set shall be fully parenthesised and make no use of the C precedence rules. |
| Language: | C |
| Severity Level: | 6 |
| Category: | EXPRESSIONS |
| Description: |
| Mixing relational and logical operators without explicit parenthesisation is a notorious
source of error in C programs.
Example: if ( a == b && c == d ) /* WRONG - precedence used */ if ((a == b ) && ( c == d )) /* RIGHT */ |
