HackerRank C++ Basic Data Types

This Problem is of Basic Data Types
Print each element on a new line in the same order it was received as input. Note that the floating point value should be correct up to 3 decimal places and the double to 9 decimal places.

#include <iostream>
#include <cstdio>
#include <iomanip>
using namespace std;

int main()
{

    int integer;
    long long1;//by default int long
    long long long2; //by default int long long
    char character;
    float floatnumber;
    double doublenumber;

    cin>>integer;
    cin>>long1;
    cin>>long2;
    cin>>character;
    cin>>floatnumber;
    cin>>doublenumber;

    cout << setprecision(20) << integer<< endl;
    cout << setprecision(20) << long1<< endl;
    cout << setprecision(20) << long2<< endl;
    cout << setprecision(20) << character<< endl;
    cout << setprecision(20) << floatnumber<< endl;
    cout << setprecision(20) << doublenumber<< endl;

    return 0;
