What is one similarity between compiled and interpreted programming languages? (5 points)

Both compiled and interpreted languages are translated one line of code at a time before moving to the next line.

Both compiled and interpreted languages can be shared with others while keeping the source code private.

Both compiled and interpreted languages are high-level languages and translate code for a computer to understand.

There are no similarities between compiled and interpreted programming languages.

Answers

Answer:

Both compiled and interpreted languages are high-level languages and translate code for a computer to understand.

Explanation:

The one similarity between compiled and interpreted languages is that they are both high-level languages.

A high-level language is a computer language written in easy to understand human language which is then converted to machine code for the computer to understand.  

A high-level language can either be interpreted or compiled.

An interpreted is a language in which the code is translated line by line before execution while a compiled language is one in which the source code is converted directly into machine language before execution.

So, the similarity between both languages is that they are high level languages and translate code for a computer to understand.

Write an expression that evaluates to true if the value of the int variable widthOfBox is not divisible by the value of the int variable widthOfBook. Assume that widthOfBook is not zero. ("Not divisible" means has a remainder.)

Answers

Answer:

The expression is:

if widthOfBox % widthOfBook != 0

Explanation:

Given

Variables:

(1) widthOfBox and

(2) widthOfBook

Required

Statement that checks if (1) is divisible by (2)

To do this, we make use of the modulo operator. This checks if (1) is divisible by 2

If the result of the operation is 0, then (1) can be divided by (2)

Else, (1) can not be divided by (2)

From the question, we need the statement to be true if the numbers are not divisible.

So, we make use of the not equal to operator alongside the modulo operator

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 a footer element as a ______ of the contact information.

Answers

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).
