Computers and Technology
1 answer:
sleet_krkn [62]3 years ago
5 0

Answer:

The only difference is the order of operations between the increment of the variable and the value the operator returns. So basically ++i returns the value after it is incremented, while i++ return the value before it is incremented.

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 />

What can you look for on a website to indicate that the information it presents is reliable?
dybincka [34]

There are several things you can look for on a website to help you figure out if the information is reliable. The first thing you should evaluate is the audience that the website is intended for. Is it intended for academics? School children? The general public?


The next thing you should look at is the author of the website. Is the author identified? Is the author an expert in their field? Can you establish the author's credibility? Is the author affiliated to an academic institution or credible organisation?


Look at the accuracy of the website. Check for spelling errors, proper grammar, and well-written text. Are there any sources cited? Are those sources credible?


You should also check to see when the information was published. Is the information up to date? Are all of the links up to date and functioning?


There is one last thing you can look at, and this is the domain of the website. Domains like .edu and .gov are more credible than .com or .net domains.
