@GODTREE 加法优先级比左移高，所以会先算加法再算左移（

咋都这么麻烦啊，附上超简代码,绝对AC

#include<cstdio>
using namespace std;
int main()
{
    int a,b,c;
    scanf("%d%d",&a,&b);
    c=a+b;
    printf("%d",c);
    return 0;
}

@ouyangluoxi 还有更简单的吗？

#include<bits/stdc++.h>
using namespace std;

int main()
{
    int n,m;
    cin>>n>>m;
    cout<<n+m<<endl;
    return 0;
}

@jinitaimei54188 不用加endl
