28
During expression evaluation, the compiler encountered the end of an expression but
not enough operands were available for evaluation. This error can occur if you
improperly specified a binary operation.
29
You specified an operation—such as an arithmetic operation other than addition or
subtraction—that was invalid for pointer operands.
30
In an assignment statement defining a value for a pointer object, the expression on the
right side of the assignment operator did not evaluate to a pointer of the exact same
type as the pointer object being assigned; that is, it did not point to the same type of
object. This warning also occurs if you assign a pointer of any type to an arithmetic
object. Note that the same message becomes a fatal error if generated for an initializer
expression.
31
The context of an expression required an operand to be integral; that is, one of the
integer types (char, int, and so on).
32
The expression specifying the type name for a cast (conversion) operation or a
sizeof expression was invalid.
missing operand
invalid pointer operation
pointers do not point to same type of object
integral operand required
invalid conversion specified
