What is the difference between writing \n before a string and after a string in C++?

Abhay Jajodia

Abhay Jajodia answered

Hi Shifa,

\n means new line.

  • If you put it before the text, it moves to a new line first, then prints the text.

    cout << "\nHello";

  • If you put it after the text, it prints the text first, then moves to the next line.

    cout << "Hello\n";

So the difference is whether the line break happens before the message or after it.

What does self-contained content mean in HTML?

Abhay Jajodia answered

Hi Cesar,

Self-contained content means a piece of content that can stand on its own as one complete unit.

In HTML,

is used for things like an image, diagram, or code snippet plus its caption, because they belong together.

Example:


  Tiger
  
A tiger

Abhay Jajodia answered

Hi SELVARATHINAM,

Headings are like a content outline.

is a main section, and

,

,
are smaller sub-sections under it.

If you jump from

to
, it can confuse screen readers and make the page structure harder to understand. It is better to go in order, like

then

for the next level.

Why is the content inside the <head> section not shown on the webpage? I thought it would display when the code runs.

Hi Onyelusi,

The is for page information the browser needs, not for content the user reads on the page. Things in include the page title, meta info, links to CSS, and scripts.

The content that shows on the webpage goes inside the .

Example:


  My Page



  
This will show on the page

</code> shows in the browser tab, but the <code><h1></code> shows on the actual page.</p><p>If you have more questions, I am here to help 😊</p></div><span class="ellipsis-dot"></span></div></div><div class="question-card__tag"><div class="language-chip language-html"><svg width="16" height="16" viewBox="0 0 16 16" fill="none" xmlns="http://www.w3.org/2000/svg"><path d="M2.31828 14.0488L1.0957 0.33667H14.5295L13.3056 14.0467L7.80443 15.5717L2.31828 14.0488Z" fill="#25265E" fill-opacity="0.67"></path><path d="M7.8125 14.8351L12.5378 13.525L13.6496 1.07104H7.8125V14.8351Z" fill="#25265E" fill-opacity="0.67"></path><path fill-rule="evenodd" clip-rule="evenodd" d="M5.5952 6.58916L7.8125 6.58916L7.82065 6.58916L11.2686 6.58916H11.7217L11.6808 7.04079L11.2856 11.4683L11.2603 11.7524L7.82065 12.7057V12.7066L7.81295 12.7087L4.36786 11.7524L4.13226 9.11188H5.82065L5.94028 10.453L7.8125 10.9587V10.9582L9.68822 10.452L9.88337 8.27093L7.82065 8.27093L7.8125 8.27093L4.05711 8.27093L3.64384 3.63645L3.60352 3.1853H7.8125H7.82065H12.0255L11.9853 3.63645L11.9085 4.48912L11.8748 4.86695L7.82065 4.86695L7.8125 4.86695L5.44148 4.86695L5.5952 6.58916Z" fill="white"></path></svg><span class="language-chip__label">HTML</span></div><div class="question-card__course-info">This question was asked as part of the<!-- --> <a target="_blank" rel="noopener noreferrer" class="question-card__course-info--title" href="/course/learn-html">Learn HTML</a> <!-- -->course.</div></div></div></div></div></div></div><div class="question-card"><div class="question-card__header"><div class="question-card__info"><div class="question-card__question"><div class="question-card__user-details"><div class="question-card__avatar-container"><div class="avatar-container avatar-profile question-card__profile-pic"><div class="avatar avatar--round question-card__profile-pic"><div class="img-alternative-letter">2</div></div></div></div><div class="question-card__user-details--bio"><div class="question-card__meta"><span class="question-card__question-date">last year</span></div><div class="question-card__user align-items-center"><span class="question-card__user-name">2023</span><img alt="country" loading="lazy" width="30" height="30" decoding="async" data-nimg="1" class="question-card__country-flag-wrapper" style="color:transparent" srcSet="https://cdn.jsdelivr.net/gh/lipis/flag-icons/flags/1x1/mx.svg?w=32&q=75 1x, https://cdn.jsdelivr.net/gh/lipis/flag-icons/flags/1x1/mx.svg?w=64&q=75 2x" src="https://cdn.jsdelivr.net/gh/lipis/flag-icons/flags/1x1/mx.svg?w=64&q=75"/><span class="question-card__action-label"> asked</span></div></div></div><div class="question-card__section-content"><a href="/discuss/html/what-is-metadata-2"><h3 class="question-card__title">What is metadata?</h3></a></div><div class="question-card__connector"></div></div><div class="question-card__content"><div class="question-card__user-details"><a class="question-card__avatar-container question-card__avatar-container--expert" href="/discuss/expert/sarthak"><img alt="Sarthak Baral" loading="lazy" width="100" height="100" decoding="async" data-nimg="1" class="question-card__profile-pic" style="color:transparent" src="https://cdn.programiz.pro/profile-pics/sarthak.jpeg"/><div class="question-card__badge question-card__badge--expert">Expert</div></a><div class="question-card__user-details--bio"><div class="question-card__meta"><span class="question-card__question-date">last year</span></div><div class="question-card__user align-items-center"><a class="question-card__user-name question-card__user-name--expert" href="/discuss/expert/sarthak">Sarthak Baral</a><span class="question-card__action-label"> answered</span></div></div></div><div class="question-card__section-content question-card__section-content--answer"><div class="question-card__answer"><div class="question-card__answer-content text-ellipsis-two-lines"><div class=""><p>Hi Ing RAMIREZ,</p><p>Metadata means data about data.
