I need the program to stop taking values when 0 is entered but in a way so that user can still enter searchvalue as shown in my code.

int i = 0;
int count = 0;
int item = 0;

int[] arr1 = new int[20];


for (i = 0; i < 20; i++)
{
    Console.Write("Enter a number (0=stop): ");
    arr1[i] = int.Parse(Console.ReadLine());
}


Console.Write("Enter a searchvalue : ");
item = int.Parse(Console.ReadLine());

for (i = 0; i < 20; i++)
{
    if (item == arr1[i])
    {
        count++;
    }
}

Console.WriteLine("Number of occurences of searchvalue (" + item + ") is : " + count);

Console.WriteLine();

What I have tried:

tried different things none of them seem to work.

Solution 1

Your not checking the value user entered in the first for loop, so the user will have to enter 20 values before exiting loop.

Check the value entered and if zero "break" out of loop.

Solution 3

You can use the break to terminate the loop.

for (i = 0; i < 20; i++)
{
    Console.Write("Enter a number (0=stop): ");
    arr1[i] = int.Parse(Console.ReadLine());
    if (arr1[i] == 0) {
        break;
    }
}

You would need to handle the program termination; perhaps another variable?
