Output of C Programs | Set 15
Predict the output of below C programs.
Output: 3 6
Explanation: ++ has precedence over + and operates right to left. Hence rightmost ++a gives a=2 and the ++a left of it gives a=3. Now, while evaluating, b=3+3. As after the second ++a, we have a=3. Hence b=3+3=6 and a=3. Hence the output.
&a is address of the whole array a. If we add 1 to &a, we get “base address of a + sizeof(a)”. And this value is typecasted to int *. So ptr – 1 points to last element of a
