好一个前导零

#include<bits/stdc++.h>
using namespace std;
struct people{
    string name;
    int gender;
    long long id;
    
};
int main()
{
	int n;
    cin>>n;
    people a[n];
    for(int i=0;i<n;i++){
        cin>>a[i].name>>a[i].gender>>a[i].id;
        if(a[i].gender == 1){
            cout<<a[i].name<<" "<<setw(18)<<setfill('0')<<a[i].id<<endl;
        }
    }
	return 0;
}
