How can I simplify this working Binary Search code in C?

Hey guys started programming in C few weeks ago learning about algothiritms, just wondering how would you make my code more simple its just a binary search function. But the only thing is you must keep the arguments the same, thanks in advance.

bool search(int value, int values[], int n)
{
    int min = values[0];
    int max = values[n-1];
    int average = (min + max) / 2;

    if(average == value)
    {
        return true;
    }

    while (average > value) 
    {
        max = average - 1;
        average = (min + max) / 2;

    }

    while (average < value)
    {
        min = average + 1;
        average = (min + max) / 2;
    }

    if (max < min) 
    {
        return false;
    }
    if (average == value) {
         printf("%i\n", average);
        return true;
    }
    else
    {
        return false;
    }
}

There are a bunch of little things you have to get right in a binary search: handle the length=0 case, make sure the position you test is always valid, make sure you don't overflow (i.e., `(low+high)/2' is not the best way to write that), make sure the new test position is always different from the previous one, etc.

After having done it like a million times, every binary search I write is now done just like this:

bool search(int[] array, int length, int valueToFind)
{
    int pos=0;
    int limit=length;
    while(pos<limit)
    {
        int testpos = pos+((limit-pos)>>1);

        if (array[testpos]<valueToFind)
            pos=testpos+1;
        else
            limit=testpos;
    }
    return (pos < length && array[pos]==valueToFind);
}

Notice that we only need to do one comparison per iteration, which is faster than most implementations that can do 2. Instead of doing the equality test inside the loop, we reliably find the position where the element to find belongs, using only one comparison per iteration, and then at the end test to see if the element we want is there.

The way we calculate testpos ensures that pos <= testpos < limit, AND it works even if length is the largest possible integer value.

This form also makes it very easy to read off the invariants you want to see, without having to think about strange boundary conditions like high<low. When you come out of the loop, pos==limit so you don't have to worry about using the wrong one, etc.

The condition in this loop is also easily adaptable to different-purpose binary searches like "find where to insert x, ensuring that it goes after all the xs that are already in the array", "find the first x in the array", "find the last x in the array", etc.

This is not a right implementation of binary search ,all conditions must be in one loop ,such as: Also max must be n-1 and not values[n-1] and min=0 instead of values[0] as also you should compare values[average] with value not just average variable.

 bool search(int value, int values[], int n){

    int min = 0;
    int max = n-1;
    int average ;

    while(max>=min){
        average = (min + max) / 2;
        if(values[average] == value)
        {
            return true;
        }

        if (values[average] > value) 
        {
            max = average - 1;
            average = (min + max) / 2;

        }

       if (values[average] < value)
        {
            min = average + 1;
            average = (min + max) / 2;
        }

    }

    return false;
}
