Here is the problem: https://www.codeeval.com/open_challenges/152/
And here is my solution. I get 100% with this code.
using System; using System.IO; using System.Collections.Generic; class Program { static void Main(string[] args) { StreamReader reader = new StreamReader(args[0]); List<string> lines = new List<string>(); using (reader) { string line = reader.ReadLine(); while (line != null) { lines.Add(line); line = reader.ReadLine(); } } for (int i = 0; i < lines.Count; i++) { int age = Convert.ToInt32(lines[i]); if(0 <= age && age <= 2) { Console.WriteLine("Still in Mama's arms"); } else if(3 <= age && age <= 4) { Console.WriteLine("Preschool Maniac"); } else if(5 <= age && age <= 11) { Console.WriteLine("Elementary school"); } else if(12 <= age && age <= 14) { Console.WriteLine("Middle school"); } else if(15 <= age && age <= 18) { Console.WriteLine("High school"); } else if(19 <= age && age <= 22) { Console.WriteLine("College"); } else if(23 <= age && age <= 65) { Console.WriteLine("Working for the man"); } else if(66 <= age && age <= 100) { Console.WriteLine("The Golden Years"); } else { Console.WriteLine("This program is for humans"); } } } }
