Which of the following statements are correct about the program below?
#includeint main() { int size, i; scanf("%d", &size); int arr[size]; for(i=1; i"%d", arr[i]); printf("%d", arr[i]); } return 0; }
|
A.
The code is erroneous since the subscript for array used in for loop is in the range 1 to size. |
|
B.
The code is erroneous since the values of array are getting scanned through the loop. |
|
C.
The code is erroneous since the statement declaring array is invalid. |
|
D.

Answer : Option C
Explanation :
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().
