Code examples

The following code example fails the check and will give a warning:

void example(char *src, char *dst) {
	while ((*src++ = *dst++));
}

The following code example passes the check and will not give a warning about this issue:

void example(char *src, char *dst) {
	while (*src) {
		*dst = *src;
		src++;
		dst++;
	}
