**Code Snippet:**
Write the output for each of the following statements. Each group is independent of the others. In the answer box, write the question number and its output.
1. `cout << "BBL\rLO\b";`
2. `cout << ((6 - 1) / 2 - 1 * 3);`
3.
```cpp
for(int x = 0; x = 1; ++x) {
cout << x + +;
if(x > 3)
break;
}
```
4.
```cpp
enum Directions {U = 5, D, L = 8, R};
cout << D << L << endl;
```
5.
```cpp
string str;
cin.ignore(20,'o');
getline(cin,str); // Assume the input is Microsoft
cout << str;
```
6.
```cpp
int arr[ ][ ] = {{11, 12, 13}, {14, 15}};
cout << arr[0][0] << endl;
cout << arr[1][2] << endl;
```
**Explanations:**
1. **Escape Characters:**
- The `\r` character moves the cursor to the beginning of the line, and `\b` moves it back one space. Therefore, "LO" overwrites the start of "BBL", and "BB" is printed.
2. **Arithmetic Expression:**
- The expression `((6 - 1) / 2 - 1 * 3)` simplifies to `5 / 2 - 3`. Integer division of `5 / 2` yields `2`, then `2 - 3` equals `-1`.
3. **For Loop with Assignment in Condition:**
- The loop condition `x = 1` assigns `1` to `x`, so the loop will run indefinitely. However, `cout << x + +;` is a syntax error due to misuse of operators.
4. **Enum Values:**
- In the enum `Directions`, `D` implicitly takes the next integer value after `U`, which is `6`.
