[编程基础]输入输出练习之精度控制3-题解(C++代码)

#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
    char a;
    int b;
    float c;
    double d;
    cin>>a>>b>>c>>d;
    cout<<a<<'\0'<<setiosflags(ios::right)<<setw(4)<<b<<'\0'<<fixed<<setprecision(2)<<c<<'\0'<<fixed<<setprecision(12)<<d<<endl;
    return 0;
}
哪里错了？
