@ZZYTCCBS 您这分离四位不对劲。要写成这样：

a=t[i]%10;
b=t[i]/10%10;
c=t[i]/100%10;
d=t[i]/1000;

这样就对了

@stanley12 sum=sum可以不写

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n,x,a,b,c,d,cnt=0;
    cin >> n;
    for(int i=1;i<=n;i++){
        cin >> x;
        a = x / 1000 % 10;
        b = x / 100 % 10;
        c = x / 10 % 10;
        d = x / 1 % 10;
        if(d-a-b-c>0) cnt++;
    }
    cout << cnt;
    return 0;
}
