What will be the output of the following C++ code? #include <stdio...
Explanation:
- Initialization:
- The given C++ code initializes a character array `str` with size 5 and assigns the values "ABC" to it.
- Output:
- `str[3]` refers to the 4th element of the array, which is beyond the bounds of the array.
- When we try to output `str[3]`, it will result in undefined behavior as we are accessing memory outside the bounds of the array.
- The output of the code will still be "ABC" because `cout < str;`="" will="" print="" the="" entire="" string="" until="" a="" null="" terminator="" is="" />
Therefore, the correct output will be ABC.
