NEW QUESTION 100
Given:

Which is true?

A. An Exception is thrown at the runtime.
B. Sum for 0 to 0 = 55
C. Compilation fails due to error on line 6.
D. Compilation fails due to error on line 7.
E. Sum for 0 to 10 = 55

Answer: D

Explanation:
Loop variables scope limited to that enclosing loop. So in this case, the scope of the loop
variable x declared at line 5, limited to that for loop. Trying to access that variable at line 7,
which is out of scope of the variable x, causes a compile time error. So compilation fails
due to error at line 7. Hence option D is correct.
Options A and B are incorrect, since code fails to compile.
