# Print Pretty – HackerRank Solution ## Problem :

Your manager gave you 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 section below.

### Input Format :

The first line contains an integer, `T`, the number of test cases.
Each of the `T` subsequent lines describes a test case as `3` space-separated floating-point numbers: `A``B`, and `C`, respectively.

### Constraints :

• `1 <= T <= 1000`
• Each number will fit into a double.

### Output Format :

For each test case, print `3` lines containing the formatted `A``B`, and `C`, respectively. Each `A``B`, and `C` must be formatted as follows:

1. : Strip its decimal (i.e., truncate it) and print its hexadecimal representation (including the `Ox` prefix) in lower case letters.
2. : Print it to a scale of `2` 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 `15` 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``````

## 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;

cout << showbase << hex << left << nouppercase << long(A) << endl;
cout << setw(15) << right << setfill('_') << showpos << fixed << setprecision(2) << B << endl;
cout << scientific << noshowpos << uppercase << setprecision(9) << C << endl;

}
return 0;

}``````
