What will be an ideal response?
```
template
int BinaryNodeTree
{
return getNumberOfNodesHelper(rootPtr);
}// end getNumberOfNodes
template
intBinaryNodeTree
getNumberOfNodesHelper(std::shared_ptr
const
{
if (subTreePtr == nullptr)
return 0;
else
return1 + getNumberOfNodesHelper(subTreePtr->getLeftChildPtr())
+ getNumberOfNodesHelper(subTreePtr->getRightChildPtr());
}// end getNumberOfNodesHelper
```

Which of the following statements is false?
a. With a BufferedOutputStream each output operation is directed to a buffer large enough to hold the data of many output operations. Transfer to the output device is performed in one large physical output operation when the buffer fills. b. With a BufferedOutputStream, a partially filled buffer can be forced out to the device at any time by invoking the stream object’s force method. c. With a BufferedInputStream, many “logical” chunks of data from a file are read as one large physical input operation into a memory buffer. d. With a BufferedInputStream, as a program requests data, it’s taken from the buffer. When the buffer is empty, the next actual physical input operation is performed.
