C# Coding Trouble

William Langly

I am really stuck on how to do this:

Prompt a user to enter a zip code, and display a message indicating whether the zip code is in the company’s delivery area.

For example if the user enters a zip code in the array, such as 60007, the output should be Delivery to 60007 ok.

If the user enters a zip code not in the array, such as 60008, the output should be "Sorry - no delivery to 60008."

Here is what i have so far:

{

static void Main()

{

string[] zips = {"12789", "54012", "54481", "54982", "60007",

"60103", "60187", "60188", "71244", "90210"};

}

Hi William,
You can use below code too.
Console.WriteLine("Please enter a zip code for checking company’s delivery area:");
            string[] zips = {"12789", "54012", "54481", "54982", "60007",
                             "60103", "60187", "60188", "71244", "90210"};
            var target = Console.ReadLine();
            if (zips.Contains(target))
            {
                Console.WriteLine("Delivery to {0} ok.", target);
            }
            else
            {
                Console.WriteLine("Sorry - no delivery to {0}.", target);
            }
            Console.ReadLine();

This code is working fine you can refer this

here is .cs file code
using System;
using System.Linq;
namespace array
{
class Program
{
static void Main(string[] args)
{
bool flag=false;
Console.WriteLine("enter pincode ");
int temp=int.Parse(Console.ReadLine());
int[] arr = {421202,420111,600007};
// check if value exsist or not
int result = Array.IndexOf(arr,temp);
for (int i = 0; i < arr.Length; i++)
{
if (arr[i] == temp)
{
flag = true;
break;
}
}
//to display final result
if (flag==true)
Console.WriteLine("Delivery to "+ temp +" pin available");
else
Console.WriteLine("sorry, Delivery to " + temp + " pin is not available");
Console.ReadKey();
}
}
}

Hi William,

You can do/achieve the same by several ways. I am sharing one of the way by which you can get the above result.
static void Main(string[] args)
        {
            Console.WriteLine("Please enter a zip code for checking company’s delivery area:");
            string[] zips = {"12789", "54012", "54481", "54982", "60007",
                             "60103", "60187", "60188", "71244", "90210"};
            var target = Console.ReadLine();
            var results = Array.FindAll(zips, s => s.Equals(target));
            if(results.Length>0)
            {
                Console.WriteLine("Delivery to {0} ok.",target);
            }
            else
            {
                Console.WriteLine("Sorry - no delivery to {0}.", target);
            }
            Console.ReadLine();
        }
I hope this will help you.
