Java performs automatic __________ of objects that are no longer referenced in a program.

If this function returns true, this function also returns:

``` 1 bool search( Node ptr, Bird & bird, Bird dove ) 2 { 3 if ( ptr == NULL ) 4 return false; 5 if ( ptr->info == dove ) { 6 bird = ptr->info; 7 return true; 8 } 9 return search( ptr->next, bird, dove ); 10 } ``` which is called for a linked list (where start points to the first node) using the lines of code: ``` if ( search( start, bird, dove ) ) cout << “search successful” << endl; ``` A. the other Bird information for the first node that does not contain dove B. a pointer to the Bird node that contains dove C. the other Bird information for the node that contains dove D. a pointer to NULL

Write a script that takes the name of a directory as an argument and searches the file hierarchy rooted at that directory for zero-length files. Write the names of all zero-length files to standard output. If there is no option on the command line, have the script delete the file after displaying its name, asking the user for confirmation, and receiving positive confirmation. A –f (force) option on the command line indicates that the script should display the filename but not ask for confirmation before deleting the file.

What will be an ideal response?
