Print Pretty

 Given a text file with many lines of numbers to format and print, for each row of  space-separated doubles, format and print the numbers using the specifications in the Output Format section below.

Input Format

The first line contains an integer, , the number of test cases.
Each of the  subsequent lines describes a test case as  space-separated floating-point numbers: , , and , respectively.

Constraints

• Each number will fit into a double.

Output Format

For each test case, print  lines containing the formatted , , and , respectively. Each , , and  must be formatted as follows:

1. : Strip its decimal (i.e., truncate it) and print its hexadecimal representation (including the  prefix) in lower case letters.
2. : Print it to a scale of  decimal places, preceded by a  or  sign (indicating if it's positive or negative), right justified, and left-padded with underscores so that the printed result is exactly  characters wide.
3. : Print it to a scale of exactly nine decimal places, expressed in scientific notation using upper case.

Sample Input

1  
100.345 2006.008 2331.41592653498

Sample Output

0x64             
_______+2006.01  
2.331415927E+03

Explanation

For the first line of output,  (in reverse, ).
The second and third lines of output are formatted as described in the Output Format section.

SOLUTIONS:

#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 */

cout << std::hex << std::left << std::showbase << std::nouppercase; // formatting

            cout << (long long) A << endl; // actual printed part

            cout << std::dec << std::right << std::setw(15) << std::setfill('_') << std::showpos << std::fixed << std::setprecision(2); // formatting

            cout << B << endl; // actual printed part

            cout << std::scientific << std::uppercase << std::noshowpos << std::setprecision(9); // formatting

            cout << C << endl; // actual printed part

    }

    return 0;
