-Regarding char and unsigned char: ANSI C is a nightmare in this
-respect. Some functions, like puts(), strchr(), and getenv(), use char
-or char*, so they work well with character constants like 'a', which
-are char, and with argv, which is char**. But several other functions,
-like getchar(), putchar(), and isdigit(), use unsigned char (converted
-to/from int). Therefore innocent-looking code can be wrong, for
-example:
-
- int c = getchar();
- if (c == 'a') ...
-
-This is wrong because 'a' is char (converted to int) and could be
-negative, but getchar() returns unsigned char (converted to int), so c
-is always nonnegative or EOF. For similar reasons, it is wrong to pass
-a char to a function that expects an unsigned char:
-
- putchar('\n');
- if (isdigit(argv[1][0])) ...
-
-Inevitably, we need to convert between char and unsigned char. This can
-be done by integral conversion (casting or assigning a char to unsigned
-char or vice versa), or by aliasing (converting a pointer to char to
-a pointer to unsigned char (or vice versa) and then dereferencing
-it). ANSI C requires that integral conversion alters the bits when the
-unsigned value is not representable in the signed type and the signed
-type does not use two's complement representation. Aliasing, on the
-other hand, preserves the bits. Although the C standard is not at all
-clear about which sort of conversion is appropriate for making the
-standard library functions interoperate, I think preserving the bits
-is what is needed. Under that assumption, here are some examples of
-correct code:
-
- int c = getchar();
- char ch;
-
- if (c != EOF) {
- *(unsigned char *)&ch = c;
- if (ch == 'a') ...
- if (isdigit(c)) ...
- }
-
- char *s = ...
- if (isdigit(*(unsigned char *)s)) ...
