precedence                  Definition                 precedence




Precedence refers to the  property of each C operator that deter-
mines priority of  execution.  Operators are executed in order of
their degree of precedence, from highest to lowest.

The  following table  summarizes the  precedence of  C operators.
The are  listed in descending  order of precedence:  those listed
higher in the table are executed before those lower in the table.
Operators  listed  on  the  same  line  have the  same  level  of
precedence.

You can always determine precedence in an expression by enclosing
sub-expressions  within   parentheses:  the  expression  enclosed
within the innermost parentheses is always executed first.
