Question

Hi I have been told to “Write code that determines if a value, say “5”, is contained in the array from task 7(a random array) by going backwards through the array starting at the end and comparing the search value with the values in the array. After the search, if the value is found print “The value has been found” otherwise print “The value has not been found”.”

I understand the creation of the random array but I am stuck on how to work backwards through it and locate the specific value.

Here is the code so far

class Program
{
    static void Main(string[] args)
    {
        int[] myArray = new int[10];
        Random rand = new Random();

        for (int i = 0; i < myArray.Length; i++)
        {
            myArray[i] = rand.Next(19);
        }

    }
}

}

Use the loop starting from largest to smallest index.

 bool found = false;
 for (int i = myArray.Length - 1; i >=0 ; i--) 
     if(myArray[i] == 5)
        found = true;
 if(found)
 {

 }
 else
 {

 }
