An identifier is the name of a program or the names of the variables, classes, methods, namespaces or interfaces within a program that are used to identify the relevant data/info.
Typically, identifiers must start with a letter (no numbers) and must not have any spaces in them, it should indicate the meaning and usage of the element being referred and i t cannot have more than 511 characters.
An example is:
<em>int money;
</em>
<em>double accountBalance;</em>
Where money and accountBalance are the identifiers.

Answer:
Explanation:
The following code is written in Java it goes through the queue that was passed as an argument, loops through it and removes all the odd numbers, leaving only the even numbers in the queue. It does not add any more data structures and finally returns the modified queue when its done.
public static Queue<Integer> evens(Queue<Integer> queue) {
int size = queue.size();
for(int x = 1; x < size+1; x++) {
if ((queue.peek() % 2) == 0) {
queue.add(queue.peek());
queue.remove();
} else queue.remove();
}
return queue;
}

cid int,
price int,
p_size varchar2(1),
CONSTRAINT chk_price CHECK (price>0),
CONSTRAINT chk_size CHECK (p_size in ('S','M','L')),
CONSTRAINT fk_cid FOREIGN KEY (cid) REFERENCES CATEGORY(cid)

The statement 'an embedded system describes computing technology that has been enclosed in protective shielding for security reasons is false.
In the field of computers and technology, an embedded system can be described as a small computer, more overly an integrated chip, that is enclosed in an electronic device in order for making the device to run. The small computer integrated into the device helps in regulating the device. The purpose of an embedded system is not for protective shielding or security reasons hence the statement above is false.
In an embedded system, a combination of computer processor, computer memory, and input/output peripheral devices is present that performs a dedicated function. Microcontrollers are used for the management of an embedded system.
