victus00 [196]

Answer:

Option A is the correct answer for the above question.

Explanation:

A Victim is a person, who faces the problem of a criminal person. Here in the question, the scenario is that a user is a victim of the identity of being theft by some other person. So the user can get known by the help of option a, which suggests that the user's credit card report display something which is not done by him then it can be the scenario, where the user can understand that he is a victim. hence option a is the correct answer where the other option is not because--

Option B suggests the user does not pay the bill on time but it is a general case because the bill is paid by the user is in every month not a single time.
Option C suggests both options (A and B) are correct, but option b is not the correct.
Option D suggests that no option is valid from the above but option A is the correct.

Leokris [45]

Using the knowledge in computational language in C++ it is possible to write a code that cryptarithm is a mathematical puzzle where the goal is to find the correspondence between letters and digits

<h3>Writting the code:</h3>

<em>#include <bits/stdc++.h></em>

<em>using namespace std;</em>

<em>// chracter to digit mapping, and the inverse</em>

Which type of image would require you to obtain permission from the author to use the image and possibly pay a royalty to the au

ASHA 777 [7]

Answer:

Copyrighted.

Explanation:

Patent can be defined as the exclusive or sole right granted to an inventor by a sovereign authority such as a government, which enables him or her to manufacture, use, or sell an invention for a specific period of time.

Generally, patents are used on innovation for products that are manufactured through the application of various technologies.

Basically, the three (3) main ways to protect an intellectual property is to employ the use of

I. Trademarks.

II. Patents.

III. Copyright.

Copyright law can be defined as a set of formal rules granted by a government to protect an intellectual property by giving the owner an exclusive right to use while preventing any unauthorized access, use or duplication by others.

Hence, a copyrighted image would require you to obtain permission from the author to use the image and possibly pay a royalty to the author for its use.
