 | | A: When C requires the Boolean value of an expression (in the if, while, for, and do statements, and with the &&, , !, and ?: operators), a false value is inferred when the expression compares equal to zero, and a true value otherwise. |
 | | A: Under ANSI C, the text inside a "turned off" #if, #ifdef, or #ifndef must still consist of "valid preprocessing tokens." This means that there must be no newlines inside quotes, and no unterminated comments or quotes (note particularly that an apostrophe within a contracted word looks like the beginning of a character constant). |
 | | ANSI C introduces new features and complexities not found in K&R C. You'll especially need to be careful of prototyped function calls; you'll probably need to insert explicit casts. |
