HP C Language Operators
The following table lists the supported HP C operators. Operators are
listed in order of precedence, from highest to lowest. All operators
listed in the same box are of equal precedence. Associativity of
operators in the following table is from left to right, unless otherwise
stated.
For HP C, the operators && and || are not short circuited as is done by
the HP C compiler; all portions of an expression involving these
operators are evaluated. Also, HP C pointer arithmetic in the debugger
is unsupported.
Full support of struct objects is provided.
