Discussion Forum : Declarations and Initializations - Point Out Correct Statements (Q.No. 6)
6.
| 1 : | typedef long a; extern int a c; |
| 2 : | typedef long a; extern a int c; |
| 3 : | typedef long a; extern a c; |
Answer: Option
Explanation:
typedef long a;
extern int a c; while compiling this statement becomes extern int long c;. This will result in to "Declaration syntax error".
typedef long a;
extern a int c; while compiling this statement becomes extern long int c;. This will result in to "Too many types in declaration error".
typedef long a;
extern a c; while compiling this statement becomes extern long c;. This is a valid c declaration statement. It says variable c is long data type and defined in some other file or module.
So, Option C is the correct answer.
