代码：```cpp

include<iostream>

using namespace std; int main() { long double a,b; cin>>a>>b; cout<<a+b; }

#include<iostream>
using namespace std;
int main()
{
    long double a,b;
    cin>>a>>b;
    cout<<a+b;
}

是这样。

#include<iostream>
using namespace std;
int main()
{
    int a,b;
    cin>>a>>b;
    cout<<a+b;
    return 0;
}

@chenyifan12 求关

你卡出科学计数法了。 @chenyifan12

顺带一提：你跟我们班同学有个同学重名


#include<iostream>
using namespace std;
int main()
{
    long double a,b;
    cin>>a>>b;
    cout<<int(a+b);
}

@chenyifan12 用 int 不好吗？

#include<iostream>
using namespace std;

int main(){
    int a,b;
    cin>>a>>b;
    cout<<a+b;
    return 0;
}

如果一定要 long double 的话，请这样写

#include<iostream>
#include <iomanip>
using namespace std;

int main(){
    long double a,b;
    cin>>a>>b;
    cout<<setprecision(0)<<fixed<<a+b;
    return 0;
}

#include <stdio.h>
int main()
{
    int a,b;
    scanf("%d%d",&a,&b);
    printf("%d\n", a+b);
    return 0;
}

@chenyifan12

用int或1long long 或long 不行吗？

这题哪有这么nan

@chenyifan12 用long long不香吗？//10年OI一场空，不开ll见祖宗

#include<bits/c++config.h>
#include<iostream>
#define l2 long long
using namespace std;
l2 x;
l2 y;
int main(){
  cin>>x>>y;
  cout<<x+y;
  return 0;
}
