Syntax
- printf format identifiers
- A whitespace character: [ \t\n\x0B\f\r] (\xhh The character with hexadecimal value 0xhh)
- Whether plain chars are signed or unsigned is machine-dependent, but printable characters are always positive.
- C, like most languages, does not specify the order in which the operands of an operator are evaluated. (The exceptions are &&, ||, ?:, and ','.)
Similarly, the order in which function arguments are evaluated is not specified. - The line nl = nw = nc = 0;sets all three variables to zero. This is not a special case, but a consequence of the fact that an assignment is an expression with the value and assignments associated from right to left. It's as if we had writtennl = (nw = (nc = 0));
