显然，printf会比cout更加适合本题的输出环境

#include<bits/stdc++.h>
using namespace std;
#define int long long
#define made return
#define in 0
#define china ;
#define rg register
#define PII pair<int,int>
int a,b,c;
signed main(){
	ios::sync_with_stdio(0),cin.tie(0),cout.tie(0);
	scanf("%d%d%d",&a,&b,&c);
	printf("%d\n%d\n%d",a,b,c);
	made in china
}
