@[SYX2022](/user/827723) 你连个 ```using namespace std;``` 都不打真的能编译成功吗

@[SYX2022](/user/827723) 哥德巴赫猜想呀，p1304这么写错了，要不给个题目链接

提供一个模板 @[SYX2022](/user/827723)
```cpp
#include<bits/stdc++.h>
#include<cstring>
#include<iostream>
#include<cmath>
#include<cstdio>
#define ll long long
using namespace std;
void ll_read(ll &x){
x=0;ll w=1;
char c=getchar();
while(c<'0'||c>'9'){
if(c=='-')
w=-1;
c=getchar();
}
while(c>='0'&&c<='9'){
x=x*10+c-'0';
c=getchar();
}
x*=w;
return;
}
void int_read(int &x){
x=0;int w=1;
char c=getchar();
while(c<'0'||c>'9'){
if(c=='-')
w=-1;
c=getchar();
}
while(c>='0'&&c<='9'){
x=x*10+c-'0';
c=getchar();
}
x*=w;
return;
}
void ll_print(ll x){
if(x<0){
putchar('-');
x=-x;
}
if(x>=10)
ll_print(x/10);
putchar(x%10+'0');
return;
}
void int_print(int x){
if(x<0){
putchar('-');
x=-x;
}
if(x>=10)
int_print(x/10);
putchar(x%10+'0');
return;
}
int main(){
return 0;
}
```

其一，你代码CE了。
其二，这关P1304什么事。
