Console Input-Output - Task 5

using System;
/*
 * Write a program that reads 3 numbers: an integer a (0 ≤ a ≤ 500),
 * a floating-point b and a floating-point c and prints them in 4 virtual
 * columns on the console.Each column should have a width of 10 characters.
 * The number a should be printed in hexadecimal, left aligned;then the number
 * a should be printed in binary form, padded with zeroes, then the number b should be
 * printed with 2 digits after the decimal point, right aligned; the number c
 * should be printed with 3 digits after the decimal point, left aligned.
