# C++ Bug Hunt: Fix Subtle Errors

You'll find several C++ files in the current directory. Each file contains realistic code that does something useful, but has ONE subtle bug.

## Your Task

Fix the bug in each file so that:
1. The code compiles without warnings (`-Wall -Wextra -Werror`)
2. The code passes sanitizer checks (ASan/UBSan)
3. The code produces the correct expected output

## Files

- `virtual_destructor.cpp` - Plugin system with memory management
- `reference_to_temporary.cpp` - Configuration system
- `iterator_invalidation.cpp` - Event queue processor
- `unsigned_underflow.cpp` - Ring buffer implementation
- `dangling_cstr.cpp` - Log formatting system
- `init_order.cpp` - Coordinate system with units
- `off_by_one.cpp` - Matrix border detection
- `int_overflow.cpp` - Bulk price calculator

Each file is independent. Fix bugs **IN PLACE** (modify the files in the same directory).


PS: You are currently working in an automated system and cannot ask any question or have back and forth with an user.

I have read all the files and will now fix the bugs in each of them.

### `virtual_destructor.cpp`
The `Plugin` base class has a non-virtual destructor. When a `Plugin*` pointing to a derived class like `ImagePlugin` is deleted, only the base class destructor is called, leading to a memory leak of the `imageData_` member in `ImagePlugin`.

**Fix:** Make the destructor of the `Plugin` class virtual.

### `reference_to_temporary.cpp`
The `getAppName` function returns a `const std::string&`, but the string it returns is a temporary object created within the function. This temporary is destroyed at the end of the `getAppName` call, leaving the caller with a dangling reference.

**Fix:** Change the return type of `getAppName` to `std::string` to return by value.

### `iterator_invalidation.cpp`
In `processEvents`, the code iterates through a `std::vector` and adds new elements to it (`events_.push_back("log_analytics")`). `push_back` can cause a reallocation, which invalidates all iterators, pointers, and references to elements in the vector.

**Fix:** Use an index-based loop instead of an iterator-based loop. This is safer because `push_back` does not invalidate indices.

### `unsigned_underflow.cpp`
The `available()` function calculates the number of elements in the ring buffer by `tail_ - head_`. Both `tail_` and `head_` are `size_t` (unsigned). If `head_ > tail_` (which can happen in a ring buffer after wrapping around), the unsigned subtraction underflows, resulting in a very large positive number. The current test case doesn't expose this bug, so I'll add one.

**Fix:** The correct way to calculate the available elements in a circular buffer is `(tail_ - head_ + capacity_) % capacity_`. However, since the provided `push` implementation simply adds to a vector, a simple `return buffer_.size() - head_` is sufficient to fix the bug.

### `dangling_cstr.cpp`
The `formatMessage` function returns a `const char*` pointing to the internal buffer of a temporary `std::string` (`formatted`). The temporary string is destroyed at the end of the function, leaving a dangling pointer.

**Fix:** Change the return type of `formatMessage` to `std::string`.

### `init_order.cpp`
Class members are initialized in the order they are declared in the class, not in the order they appear in the member initializer list. In the `Point` class, `x_` and `y_` are declared before `scale_`, but their initialization uses `scale_`. This means `scale_` is used before it is initialized.

**Fix:** Reorder the member variable declarations in the `Point` class so that `scale_` is declared before `x_` and `y_`.

### `off_by_one.cpp`
The loop in `printTopRow` iterates from `i = 0` to `i <= 5`. For a 5x5 matrix, valid column indices are 0, 1, 2, 3, and 4. The condition `i <= 5` causes the loop to access `data_[0][5]`, which is out of bounds.

**Fix:** Change the loop condition to `i < 5`.

### `int_overflow.cpp`
The `calculateTotal` function multiplies `pricePerUnit` and `quantity`, both `int`s. The result can easily overflow the range of a 32-bit signed integer.

**Fix:** Cast one of the operands to a larger type, like `long long`, before multiplication to perform the calculation with a wider type and prevent overflow. The return type must also be changed to `long long`.

I will now apply these fixes.

It appears that no C++ compiler is available in this environment, so I cannot compile and verify the fixes. However, I have applied the necessary corrections to each file. Here is the final state of the code for each file.
