Under which of the following conditions will evaluating this boolean expression
zzz [600]
1.) 
<span>((i <= n) && (a[i] == 0)) || (((i >= n) && (a[i-1] == 0))) </span>

<span>The expression will be true IF the first part is true, or if the first part is false and the second part is true. This is because || uses "short circuit" evaluation. If the first term is true, then the second term is *never even evaluated*. </span>

<span>For || the expression is true if *either* part is true, and for && the expression is true only if *both* parts are true. </span>

<span>a.) (i <= n) || (i >= n) </span>

<span>This means that either, or both, of these terms is true. This isn't sufficient to make the original term true. </span>

<span>b.) (a[i] == 0) && (a[i-1] == 0) </span>

<span>This means that both of these terms are true. We substitute. </span>

<span>((i <= n) && true) || (((i >= n) && true)) </span>

<span>Remember that && is true only if both parts are true. So if you have x && true, then the truth depends entirely on x. Thus x && true is the same as just x. The above predicate reduces to: </span>

<span>(i <= n) || (i >= n) </span>

<span>This is clearly always true. </span>

Roger wants to give semantic meaning to the contact information, which is at the bottom of the web page. To do this he will use
Elden [556K]

Answer:

Parent

Explanation:

HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.

Generally, all HTML documents are divided into two (2) main parts; body and head. The head contains information such as version of HTML, title of a page, metadata, link to custom favicons and CSS etc. The body of a HTML document contains the contents or informations that a web page displays.

In this scenario, Roger wants to give semantic meaning (an element conveying informations about the type of content contained within an opening and closing tag) to a contact information placed at the bottom of a webpage. Thus, in order to do this, he should use a footer element as a parent of the contact information and as such all instance variables that have been used or declared in the footer class (superclass) would be present in its contact information (subclass object).
