}

| [A]. |
10 | [B]. |
11 | | [C]. |
No output | [D]. |
Error: ++needs a value |
Answer: Option E
Explanation:
This program will show an error "Cannot modify a const object".
Step 1: const int i=0; The constant variable 'i' is declared as an integer and initialized with value of '0'(zero).
Step 2: printf("%d\n", i++); Here the variable 'i' is increemented by 1(one). This will create an error "Cannot modify a const object".
Because, we cannot modify a const variable.
