The following program uses function multiple to determine whether the integer entered from the keyboard is a multiple of some integer X. Examine function multiple, then determine the value of X.

Question

```
// This program determines if a value is a multiple of X.
#include
using namespace std;

bool multiple( int );

int main()
{
int y;

cout << "Enter an integer between 1 and 32000: ";
cin >> y;

if ( multiple( y ) )
cout << y << " is a multiple of X" << endl;
else
cout << y << " is not a multiple of X" << endl;
} // end main

// determine if num is a multiple of X
bool multiple( int num )
{
bool mult = true;

for ( int i = 0, mask = 1; i < 10; i++, mask <<= 1 )
if ( ( num & mask ) != 0 )
{
mult = false;
break;
} // end if

return mult;
} // end function multiple
```

Answer 1

The value of X is 1024.
