一個簡單的 Lamdba 運算式:
|
||||
```cpp
|
||||
[] (int x, int y) -> bool {
|
||||
return x < y;
|
||||
}
|
||||
```
|
||||
|
||||
- 以中括號開頭,中括號被稱為*lamdba 導入器(lamdba introducer)*
|
||||
- 小括號裡面是*lamdba 參數列表(lambda parameter list)*
|
||||
- 如果沒有參數,小括號可以省略,`[] () {...}` 可以簡寫成 `[] {...}`
|
||||
- 箭號(`->`)後面是回傳的型別,如果沒寫就由 `return` 自動推斷
