(761) sizeof yields 0
The code generator has taken the size of an object and found it to be zero. This almost certainly
indicates an error in your declaration of a pointer, e.g. you may have declared a pointer to a zero
length array. In general, pointers to arrays are of little use. If you require a pointer to an array of
objects of unknown length, you only need a pointer to a single object that can then be indexed or
incremented.
(763) constant left operand to "? :" operator
The left operand to a conditional operator ? is constant, thus the result of the tertiary operator ?:
will always be the same, e.g.:
(764) mismatched comparison
A comparison is being made between a variable or expression and a constant value which is not in
the range of possible values for that expression, e.g.:
(765) degenerate unsigned comparison
There is a comparison of an unsigned value with zero, which will always be true or false, e.g.:
will always be true, because an unsigned value can never be less than zero.
(766) degenerate signed comparison
There is a comparison of a signed value with the most negative value possible for this type, such
that the comparison will always be true or false, e.g.:
will always be true, because an 8 bit signed char has a maximum negative value of -128.
