思路

因为是四位数，位数确定，所以可以用 char 来写。

code
```
#include<bits/stdc++.h>
using namespace std;
char a,b,c,d;
int main(){
  cin>>a>>b>>c>>d;
  cout<<a-'0'+b-'0'+c-'0'+d-'0';
  return 0;
}
```

#include<bits/stdc++.h> using namespace std; int main(){ int a,b,c,d,e,f; cin>>a; b=a/1000; c=a/100%10; d=a/10%10; e=a%10; f=b+c+d+e; cout<<f; return 0; }

拿char多好做

#include<bits/stdc++.h>
using namespace std;
int main()
{
 char a,b,c,d;
 cin>>a>>b>>c>>d;
int sd=a+b+c+d-4*48;
cout<<sd;
return 0;
}
