都这样写了可以不用结构体了吧

#include<iostream> using namespace std; int main(){ int n; cin>>n; for(int i=1;i<=n;i++){ string name; double fen; int age; cin>>name>>fen>>age; cout<<name<<' '; printf("%.1f %d\n",fen,age); } return 0; }

保留一位小数
要用printf输出分数

1.分数要用printf,来保留一位小数 2.数组大小设为100即可

请说出里面有多少知识点

#include<array>
