A.
The code is erroneous since the statement declaring array is invalid. |
|
B.
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 |
