What will be output for the following code?
Answer: A
Correct answer: Error, though the code this depends on is missing
The program listing this question asks about is absent from the record - only the words “What will be output for the following code?” survive, with nothing following them. The four options are “Error”, 5, 6 and 2, and the item is keyed to “Error”, so the original code presumably contained a mistake the compiler would reject. Which mistake cannot be recovered from what remains. The topic is structures, unions and enumerations, where the commonest sources of a compile error are using the dot operator on a pointer to a structure instead of ->, omitting the tag or the semicolon that must follow a struct definition, assigning to an enumeration constant, or taking sizeof an incomplete type. The item needs its listing restored before it can be worked.
