Q49
Which of the following statements are correct about the program below? #include void main() int size, i; scanf("%d", &size); int arr[size]; for(i=1; i<=size; i++) scanf("%d", arr[i]); printf("%d", arr[i]);
A.
The code is erroneous since the statement declaring array is invalid.
AnswerB.
The code is erroneous since the subscript for array used in for loop is in the range 1 to size.
C.
The code is correct and runs successfully.
D.
The code is erroneous since the values of array are getting scanned through the loop.
E.
None of these
Answer: Option A
Solution
Answer: Option A
Solution:
The statement int arr[size]; produces an error, because we cannot initialize the size of array dynamically. Constant expression is required here.
Example: int arr[10];
One more point is there, that is, usually declaration is not allowed after calling any function in a current block of code. In the given program the declaration int arr[10]; is placed after a function call scanf().
