Answer:

C. FIFO

Explanation:

The first-in, first-out (FIFO) page replacement algorithm is a low-overhead algorithm that requires work on the part of the operating system. On a page fault, the frame that has been in memory the longest is replaced.

Using FIFO algorithm implies that

a page which was brought into memory first will be removed first since variable was initialized very early. it is in the set of first in pages that will be removed.

It is the simplest page replacement algorithm. The operating system keeps track of all pages in the memory in a queue, the oldest page is in the front of the queue. When a page needs to be replaced page in the front of the queue is selected for removal that is first in first out.

A memory page containing a heavily used variable that was initialized very early and is in constant use is removed, then the page replacement algorithm used is called First In First Out.

Assume the following variable definition appears in a program:
AnnZ [28]

Answer:

cout << setprecision(2)<< fixed << number;

Explanation:

The above statement returns 12.35 as output

Though, the statement can be split to multiple statements; but the question requires the use of a cout statement.

The statement starts by setting precision to 2 using setprecision(2)

This is immediately followed by the fixed manipulator;

The essence of the fixed manipulator is to ensure that the number returns 2 digits after the decimal point;

Using only setprecision(2) in the cout statement will on return the 2 digits (12) before the decimal point.

The fixed manipulator is then followed by the variable to be printed.

See code snippet below

<em>#include <iostream>  </em>

<em>#include <iomanip> </em>

<em>using namespace std;  </em>

<em>int main()  </em>

<em>{  </em>

<em> // Initializing the double value</em>

<em> double number = 12.3456;  </em>

<em> //Print  result</em>

<em> cout << setprecision(2)<< fixed << number;  </em>

<em> return 0;  </em>

<em>}  </em>

<em />
