So I have an input file. It consists of 40 numbers. The first 20 numbers are input into an array (I've checked this, they're actually there). I then close and re-open the input file. I compare the first 20 numbers in the input file against my array using sequential search. This means they should all be successful. I then compare the next 20 numbers against the numbers in my array, they should all be unsuccessful searches. My array is unsorted at this point.

The problem I'm running into is that the last number for successful is never found using sequential. I'm not sure how to fix this.

Here is the sequential search function: 

```
length = 19;

void Search::sequential(ItemType item, bool& found)
{ 
  int place = 0;
  while (place < length && item != list[place])
    place++;
  found = (place < length); 
}

```

And here is my successful/unsuccessful loops

```
outFile << "\n\n ************Sequential Successful ********** \n";
outFile << endl << "ID" << endl;

inFile >> num;
for(int i=0; i<=length && inFile; i++)
{
  search.sequential(num, found);
  if (found)
    outFile << num << endl; 

  inFile >> num;
} 

//sequential unsuccessful
outFile << "\n\n ************Sequential unsuccessful ********** \n";
outFile << endl << "ID" << endl;

for(int i=0; i<=length && inFile; i++)
{
  search.sequential(num, found);
  if (!found)
    outFile << num << endl; 

  inFile >> num;
}

```

However, my output is: 

```
 ************Sequential Successful **********

```

If I remove the "if (found)" statement everything works perfectly, but how do I get around this without removing that?

Thanks in advance

---------------edit---------------

Okay, when I changed length to 20 it still didn't seem to work. I'm so lost.

Here is where I create the array

```
inFile >> num;
for (int i=0; i<length && inFile; i++)
{
  search.addToList(num);
  inFile >> num;
}

```

and here is the addToList function

```
 void Search::addToList(ItemType num)
 {
   if (index < length)  //ive tried taking out this statement just to see if it makes a difference and it didn't
   {
     list[index] = num;
     index++;
   }
 }

```

I initialize index to 0 in the constructor

This is how I declare the array

```
    ItemType list[length]; 

```

IT WORKS!!!! Thank you all SO much! I really appreciate it so much.
