Answer:

The code will display the following on the screen:-

2

0

2

Explanation:

The output is like this because x{2} assigns the value 2 to the integer x.First the value of x is printed on the screen that is 2 and that newline is used to go to the next line.After that function is called doSomething with x passed as the argument. doSomething function assigns the value zero to the variable passed and prints it on the screen.So the next line is 0.Since x is passed by value so no changes will appear in the original argument.Hence the last line printed is 2.

devlian [24]

Answer:

Answer:

the logo of the company or corporation

Explanation:

The logo of a website is technically the logo of the brand which has the rights to all of the information represented on the site and ultimately the intellectual property of the site itself. Since there are various board members that usually make up the company that owns the intellectual property, the logo is a way of representing all of these members as a single entity.
