had to do a program that did a binary search for the number 5 but for some reason its not being found...here's my code whats wrong..

```
#include <iostream>
using namespace std;
const int SIZE=15;
int binarySearch(const int, int, int[]);
int main()
{
int posints[SIZE]={10, 36, 87, 95, 100, 110, 194, 195, 297, 301, 314, 358, 451,467, 500};
int searchValue=500;
int results = binarySearch(SIZE, searchValue, posints);
return 0;
}
int binarySearch (const int SIZE, int searchValue, int array[] )
{
int first=0, last= SIZE-1, midpoint=(first+last)/2, position=-1,count=1;
bool found=false;
while (found=false && first<=last)
{
cout<<"Pass"<<count<<endl<<"Left: "<<first<<endl<<"Right: "<<last<<endl<<"Midpoint: "<<midpoint<<endl;
cout<<"a[midpoint]: "<<array[midpoint]<<endl<<endl;
if(searchValue == array[midpoint])
{
found=true;
position=midpoint;
cout<<"Value found!";
}
else if(searchValue>array[midpoint])
last=midpoint-1;
else
first=midpoint+1;
count++;
}
if (position=-1)
cout<<"Value not found!";
return position;
}
```
