Error and Warning Messages
(353) sizeof external array "*" is zero
The size of an external array evaluates to zero. This is probably due to the array not having an
explicit dimension in the extern declaration.
(354) possible pointer truncation
A pointer qualified far has been assigned to a default pointer or a pointer qualified near, or a default
pointer has been assigned to a pointer qualified near. This may result in truncation of the pointer and
loss of information, depending on the memory model in use.
(355) implicit signed to unsigned conversion
A signed number is being assigned or otherwise converted to a larger unsigned type. Under the
ANSI "value preserving" rules, this will result in the signed value being first sign-extended to a
signed number the size of the target type, then converted to unsigned (which involves no change
in bit pattern). Thus an unexpected sign extension can occur. To ensure this does not happen, first
convert the signed value to an unsigned equivalent, e.g.:
will perform a sign extension of the char variable to the longer type. If you do not want this to take
place, use a cast, e.g.:
(356) implicit conversion of float to integer
A floating point value has been assigned or otherwise converted to an integral type. This could result
in truncation of the floating point value. A typecast will make this warning go away.
double inc_flt(f) /* the parameter f will be converted to double type */

signed char sc;
unsigned int ui;
ui = sc;
ui = (unsigned char)sc;
return f * 2;
/* if sc contains 0xff, ui will contain 0xffff for example */
