C Sample code Linear Search Algorithm Linear search is method for searching a value within an array. It 'sequentially' checks one by one of the arrays for the 'target element' until 'match is found' or until all the elements have Largest Rectangular Area in a Histogram Get minimum of two numbers in hist. Get the 'middle index' from corner. Even though temporarily commented, the snippets are also production, debugged code. This page has over 13,000 words of VB6 and SQL source code snippets, examples, samples, etc. A lot of the syntax remains eternal in the land of Visual Basic. Hopefully these code libraries will serve people well for many years.

In this chapter we will show some basic HTML examples.
Don't worry if we use tags you have not learned about yet.
HTML Documents
All HTML documents must start with a document type declaration: <!DOCTYPE html>
.
The HTML document itself begins with <html>
and ends with </html>
.
The visible part of the HTML document is between <body>
and </body>
.
Example
<html>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>
The <!DOCTYPE> Declaration
The <!DOCTYPE>
declaration represents the document type, and helps browsers to display web pages correctly.
It must only appear once, at the top of the page (before any HTML tags).
The <!DOCTYPE>
declaration is not case sensitive.

How to View HTML Source?
Have you ever seen a Web page and wondered 'Hey! How did they do that?'
View HTML Source Code:
Right-click in an HTML page and select 'View Page Source' (in Chrome) or 'View Source' (in Edge), or similar in other browsers. This will open a window containing the HTML source code of the page.
Inspect an HTML Element:

Right-click on an element (or a blank area), and choose 'Inspect' or 'Inspect Element' to see what elements are made up of (you will see both the HTML and the CSS). You can also edit the HTML or CSS on-the-fly in the Elements or Styles panel that opens.
