Interview Question in LINQ
Interview Question :: Question dealing with methods and arrays as a way to simply this code |
I am trying to write a program that prompts 5 users to enter in their names and ages. the names and ages are then put into a set of arrays. after the information has been entered. the program displays the name of the oldest.
I realize that I could use quite a bit of if then statements to get my program to display the oldest persons name. but there has to be an easier way. I know I could use a method as well as a loop but I could not figure it out how to do it. please assist.
the code is listed.....
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
public static void Main(string[] args)

int[] agenmber = new int[5];
string[] agetxt = new string[5];
string[] namesjumble = new string[5];
//information on the first person
Console.WriteLine("USER 1 INFORMATION");
Console.WriteLine("");
Console.WriteLine("what is your name?");
namesjumble[0] = Console.ReadLine();
Console.WriteLine("Hello {0}, what is your age?", namesjumble[0]);
agetxt[0] = Console.ReadLine();
agenmber[0] = Convert.ToInt32(agetxt[0]);
Console.WriteLine("the first person to enter a name is {0} with an age of {1} years", namesjumble[0], agetxt[0]);
// information for the second person
Console.WriteLine("");
