Why we can not see objects around us in the dark

malfutka [58]

Answer:

We see an object when light falls on it and gets reflected from its surface and enters our eyes. In a dark room, there is no source of light. no light falls on the surface of objects and we do not see them. This is why we cannot see the objects in a dark room.

When writing test methods, what functionality is verified by the system method "runAs()"?

olchik [2.2K]

Answer:

The main functionality verified by this test method command is user sharing record.

Explanation:

Generally, every apex code runs in system mode.

Apex is strong object-oriented programming language that allows the developers to execute flow and transaction control.

Using syntax which look like java and acts as databases, Apex allows the developer to add any type of business logics to an event which can include button, clicks records or visual pages.

Apex code can be initiated by web service request.

The permissions and record sharing of current user are not consider by apex codes.

Now the system method runAs() will allow you to take or write a test method which will basically change the user context to an existing or an new user, so that the record sharing will take place.

runAs() command will not change or anything done with user permissions or permission levels, it will only record sharing of the user.

When you use runAs() command the original and true context will run after the test method is once completed under the command of runAs().

The runAs() has no concern with the user license.

If there is no or expired your personal or organization license you can just make a new user with this runAS() command.

In using this command we have to make a private class by the name of this test and then our further code to make a user , afterwards which we will the true and original code of ours which we want to run.

There are many other uses of runAs() like

 Mixed DML operations in test by opening the DML operations.

 We can also use it as a version which will take a package as a version argument. This will cause the code a specific version.

runAs(System.Version) is the command used for this.

Write the following program in C++ to print:

Alenkinab [10]

1.
#include <iostream>#include <string>
using namespace std;
int main(){ string chars; // This is where we will put our @ signs and print them for(int x=0;x < 5; x++){
chars = chars + '@'; // This will concatenate an @ sign at the end of the variable cout << chars << "\n"; }}

2.
#include <iostream>#include <string>
using namespace std;
int main(){ string name; // Our variable to store the name cout << "What is your name? \n"; // Asks the user for their name cin >> name; cout << "\nWell, hello " << name << "!";}

3.
#include <iostream>#include <string>
using namespace std;
int main(){ int number; // Our variable cout << "Enter a number\n"; // Asks for a number cin >> number; cout << "You entered " << number << "%!";}

4.
#include <iostream>#include <string>
using namespace std;
int main(){ int number; // Our variable cout << "Enter a number\n"; cin >> number;
int check = number % 2; // The modulo operator (the percent sign) gets the remainder of the quotient if (check == 0) { cout << number << " is even!"; // If the remainder is 0 then it prints out "x is even" } else { cout << number << " is odd!"; // If the remainder is not 0 then it prints out "x is odd" }}

5.
#include <iostream>#include <string>
using namespace std;
int main(){ float r; // Our variable cout << "Enter a radius\n"; cin >> r; if (r < 0){ cout << "Lol. No."; // If the radius is less than zero print out that message } float circumference=2*3.14*r; float area=r*r*3.14; cout << "\n\n Circumference of circle: " << circumference; cout << "\n Area of circle: " << area;}

What security weaknesses/vulnerabilities exist in Wireless local area network device hardware and software?

AfilCa [17]

Answer:

Explanation:

There are many weaknesses/vulnerabilities, some of which are the following...

Default Network Hardware, many individuals will go out and buy a new router and install it in their home. These devices come with a preset configuration including a preset security password which is many times a default password used for every router of the same model. This can be easily obtained by anyone who can then access the network.

Access Point hacking, an experienced individual can use a packet sniffer to detect the SSID that is frequently sent from the router in order to create an access point to be able to access the network.

WEP encryption is another vulnerability. These are very low security passwords that can be cracked using different software in a short period of time.

These are some of many vulnerabilities that wireless local networks have, but there are also many precautions and security measures that can be taken to prevent them.
