array of string

For This program i have no idea what to do, if guys don`t mind, help pls... thank you.

Use a loop to force the user to enter valid integer in the range 2 to 5 inclusive, and handle all exceptions.
The program will then input the strings into the array.

Find and display the shortest string stored in the array.

Display the strings that are stored in the array in reverse order,

As well, display string length for each string as shown below.

Here is an example of the program running:

How many strings do you wish to enter: 3

Enter string #1: Cats and rats
Enter string #2: just rats
Enter string #3: rats

The shortest strings is "rats"

rats 4
just rats 9
Cats and rats 13

Try the following:

using System;

class Program

{

static void Main()

{

int num;

bool isValid;

while(true)

{

Console.Write("How many strings do you wish to enter: ");

isValid = int.TryParse(Console.ReadLine(), out num);

Console.WriteLine();

if (!isValid)

Console.WriteLine("Not a valid number, try again\n");

else if (num < 2 || num > 5)

Console.WriteLine("Must be between 2 and 5, try again\n");

else

break;

}

Console.WriteLine();

string[] strings = new string[num];

int index = -1;

int shortest = 100; // impossibly high value

for(int i = 0; i < num; i++)

{

Console.Write("Enter string #{0}: ", i + 1);

strings[i] = Console.ReadLine();

if (strings[i].Length < shortest)

{

index = i;

shortest = strings[i].Length;

}

Console.WriteLine("\nThe shortest string is \"{0}\"", strings[index]);

Console.WriteLine();

for(int i = num -1; i >= 0; i--)

{

Console.WriteLine("{0} {1}", strings[i], strings[i].Length);

}

Console.ReadKey();

}

   }

   Console.ReadKey();

   }
