(361) function declared implicit int
Where the compiler encounters a function call of a function whose name is presently undefined, the
compiler will automatically declare the function to be of type int, with unspecified (K&R style)
parameters. If a definition of the function is subsequently encountered, it is possible that its type
and arguments will be different from the earlier implicit declaration, causing a compiler error. The
solution is to ensure that all functions are defined or at least declared before use, preferably with
prototyped parameters. If it is necessary to make a forward declaration of a function, it should be
preceded with the keywords extern or static as appropriate. For example:
(362) redundant & applied to array
The address operator & has been applied to an array. Since using the name of an array gives its
address anyway, this is unnecessary and has been ignored, e.g.:
(364) attempt to modify * object
Objects declared const or code may not be assigned to or modified in any other way by your
program. The effect of attempting to modify such an object is compiler-specific.
(365) pointer to non-static object returned
This function returns a pointer to a non-static (e.g. auto) variable. This is likely to be an error,
since the storage associated with automatic variables becomes invalid when the function returns,
e.g.:
342
void set(long a, int b); /* I may prevent an error arising from calls below */
void main(void)
{
}
int array[5];
int * ip;
ip = &array; /* array is a constant, not a variable; the & is redundant. */
const int out = 1234; /* “out” is read only */
out = 0;
set(10L, 6);
/* by here a prototype for set should have seen */
/* woops -- writing to a read-only object */
