HackerRank Print Pretty solution in c++ programming

In this HackerRank Print Pretty problem in c++ programming language, you have Given a text file with many lines of numbers to format and print, for each row of 3 space-separated doubles, format and print the numbers using the specifications in the Output Format.

HackerRank Print Pretty problem solution in c++ programming.

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

int main() {
  int T; cin >> T;
  cout << setiosflags(ios::uppercase);
  cout << setw(0xf) << internal;
  while(T--) {
    double A; cin >> A;
    double B; cin >> B;
    double C; cin >> C;

    /* Enter your code here */
        // LINE 1 
        cout << hex << left << showbase << nouppercase; // formatting
        cout << (long long) A << endl; // actual printed part

        // LINE 2
        cout << dec << right << setw(15) << setfill('_') << showpos << fixed << setprecision(2); // formatting
        cout << B << endl; // actual printed part

        // LINE 3
        cout << scientific << uppercase << noshowpos << setprecision(9); // formatting
        cout << C << endl; // actual printed part

  }
  return 0;

Second solution

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

int main(){
    int T; cin >> T;
    cout << setiosflags(ios::uppercase);
    cout << setw(0xf) << internal;
    while(T--) {
        double A; cin >> A;
        double B; cin >> B;
        double C; cin >> C;

        /* BEGIN: unlocked */
          // Sample solution:
            cout << left << hex << showbase << nouppercase;
            cout << (long long) A << endl;

            // One decimal place, right aligned, show sign, and fill left with underscores
            cout.precision(2);
            cout << showpos << fixed << setfill('_') << setw(15) << right;
            cout << B << endl;

            // Scientific notation with 9 decimal places
            cout.precision(9);
            cout << noshowpos << uppercase << scientific;
            cout << C << endl;
        /* END: unlocked */
    }
    return 0;
