```cpp
#include <bits/stdc++.h>
using namespace std;int main(){long long a,b;cin>>a>>b;cout<<a+b;}
```
2行c++最短

```cpp
#include<iostream>
main(){long long a,b;std::cin>>a>>b;std::cout<<a+b;}
```
72 B 码长 C++11.
还有更短的代码。

还能凹，67 B
```cpp
#include<iostream>
main(){long a,b;std::cin>>a>>b;std::cout<<a+b;}
```

@[Libingyue2011](/user/886055) include 可以换成 import

哦，66 B.

有史以来行数最少的"$A+B$"代码：
```
main(){long long a,b;__builtin_scanf("%lld%lld",&a,&b);__builtin_printf("%lld",a+b);}
```
补充:__builtin_scanf()是**GCC**内建函数,__builtin_printf同理.
NOI系列赛事中,理论上来讲是可以使用的(NOI Linux使用GCC)但不推荐.

@[TH911](/user/967959) 哇，这么精简
by 4041nofoundGeoge @ 2024-08-14 15:43:36
```cpp
修炼成橙名了，该知道怎么短了
#include<csdio>
int main(){int a,b;scanf("%d%d",&a,&b);printf("%d",a+b);}
```

除了#inc......其他都放一行

Java一行（滑稽
```java
import java.util.*;public class Main{public static void main(String args[])throws Exception{Scanner i=new Scanner(System.in);int a=i.nextInt(),b=i.nextInt();System.out.println(a+b);}}
```
