So to ensure that nothing remains left in memory and to start a new calculation we often see people hitting clear button couple of times. It is not due to a flaw in the calculator’s design.

Ans: The <!doctype> is an element used to indicate what type and version of html is been used. <!doctype> is usually initialised under the <html> tag. This also does not have an end element and is not case sensitive. The <!doctype> is more important in older versions of HTML, such as the version 4.0.1 since indicating the <!doctype> helped in the process of document type definition (DTD). This is because HTML 4.0.1 was based on standard generalised markup language (SGML). This is not the same case as for HTML5 since that is not dependent on SGML and hence no data type definition is required. Hence, in HTML5 it is not necessary to indicate <!doctype> at the beginning.

Such data is stored in different areas of the website and the website can access most of the data stored by itself.
