C++, Random Number Generator Return using user inputted value

Given the task of seeing if a user defined integer returns as a given value in an array of ten choices. Those choices are displayed from a random number generator from 0-100. If the function returns a flag as true it is to record that the user given value is in the array. I am also using linear search as the recursive function. I have the function beneath the main and I have put in three error checks. From what I can tell the function is able to accurately read what value the user inputted, when/if the flag is triggered, and to record the value. The issue I am running into is when the function returns to the main and says whether or not it has found the number (if - else statement), it only return the value of 1 and continuously states that it has found the value.

For Note, I have set the random number generator down to the values of 0-20 in order for it not to take forever trying. I do not think the time elements are used for anything either but just incase, I added them.

Based on whether or not your the used inputted value is found, one should find the 'Found it' cout error checker working along with the state of the flag error checker but it should show the Integer Returned checker returning 1 or -1 (it seems in the test code shown below it returns 64?).

I know this is a lot, my first question on this site.

    srand(time(NULL));

    for (int x = 0; x < ARRAY_SIZE; x++)
    {
        myArray[x] = (rand() % 20) + 1;
    }
