<h3>Answer: B. Undo</h3>

Explanation:

This command is often found under the "edit" menu of many programs. On the toolbar, the undo button is a backwards (sometimes curved) arrow. More specifically, the arrow points to the left as if to mean "go back and fix". Likely it points to the left due to many western languages reading from left to right, so the undo arrow goes in the opposite direction.

In contrast, the "redo" button points in the other direction to repeat the last action you applied. The redo button also undoes whatever the undo button did. For instance, if you deleted a word and then hit undo, then the word would come back. Hitting redo will delete the word again.

How would this requirement be implemented?

Answer:

B. Using a Rate Rule in the Community Manager

Explanation:

Rate rules are techniques to protect your community from spammers and web bots that attack or spam your community by posting the similar message several times in a row. You can build rate rules to alert your community moderators of suspicious spammer-like activities in your community or freeze a member on the spot.

Take for example, when the universal shipping introduces a rate rule to their comunity, Community Moderators will now be alerted when a member post more than one file to the community within a 15-minute window thereby making them frooze the account accordingly.

If you want a user to enter exactly 20 values, which loop would be the best to use?

Hitman42 [59]

Answer: For loop

Explanation:

Using the for loop we can get the exact number of values/outcomes we require.

For example: printf(enter 20 numbers");

for(int i=0; i<20;i++)

{

scanf("%d", &number);

}

So, this is an implementation of for loop in C. Using it we can enter exact 20 numbers not less or more than that.

Therefore, for loop is the answer.

Function prototypes and function definitions look similar because they have the same function heading. In a function prototype t

hjlf

Answer:

In a function prototype the heading is followed by a semicolon, whereas in a function definition the heading is followed by a function block.

Explanation:

As the function prototype only declares the function and the function definition defines the operations in the function.

e.g:

add(int x, int y); is the prototype

add(int x, int y)

{

int sum;

sum $=$ x $+$ y;

} is the function definition.

Identify any eight new programming languages and classify them based on their functionality.

shepuryov [24]

Answer:

Some of the new programming languages are R, Python, Haskell, Swift, C++, Java, Javascript and PHP.

However, you should know that in general sense there are three types of programming languages.

R is a pure object-oriented programming language being used for scientific purposes, and now it is being used extensively for machine learning as well.

Python is also a pure object-oriented programming language, and it is being used for mainly machine learning. However, you need to keep in mind that it supports the functional programming paradigm as well.

Haskell is a functional programming language and is the best in the functional paradigm as well. You can compare it with LISP, FORTRAN and PASCAL or COBOL, and you will find that Haskell is the best.

Swift is a pure object-oriented programming language, And by pure it means it never cheats anybody like if it says a variable is an int, it will be an int and not like C# here a string data type can be an integer data type. And this is not the correct thing. However, if you study in deep, you will find it is a necessary evil.

C++ and Java are imperative programming languages.

The Javascript and PHP are the scripting languages that support the object-oriented programming concepts but not fully, and they too fall under the imperative programming language list.

Explanation:

The answer is self explanatory.
