- 變數宣告的方式變了
|

- Old: `int a = 3;`
|

- New: `int a {3};`
|

|

- `if`裡面可以宣告變數

```cpp

unique_ptr<uint8_t[]> buffer = new uint8_t[256];

- 新方法：

```cpp
|

auto buffer = std::make_unique<uint8_t[]>(256);

```
|

- `share_ptr`: 可以複製，但要避免循環參考問題
|

|

- 透過refernce傳遞array參數
|

- 考慮一個帶有長度的陣列要傳到function裡面，但是又希望在function面可以指定陣列長度

double value[] { 1.0, 2.0, 3.0 }; // Error!

double value[] { 1.0, 2.0, 3.0, 4.0, 5.0 }; // Pass!
