Pass the function the input string that needs to be encoded or decoded, and a flag that is set to to encode into Morse-code and is set to 1 to decode into English. Use pointers for all strings.
Morse code is a way of communicating text data that may be directly comprehended by an experienced listener or observer without the need for additional tools. It consists of a series of on-off tones, lights, or clicks.
It bears the name Samuel F. B. Morse, who created the telegraph. The algorithm is quite basic. Every letter of the English alphabet is replaced by a succession of dots and dashes, or occasionally just a single dot or dash, and vice versa. Each string of text is transformed into a series of dots and dashes. Each character is transformed to its corresponding Morse code for this and added to the encoded message. The space is exactly reproduced in this place. We have thought about both alphabets and numbers.

from origin 'null' has been blocked by cors policy: cross origin requests are only supported for protocol schemes: http, data, isolated-app, chrome-extension, chrome, https, chrome-untrusted. react
Where from origin 'null' has been blocked by cors policy and cross origin requests are only supported for protocol schemes: http, data, isolated-app, chrome-extension, chrome, https, chrome-untrusted, this error can occur in React when using the fetch API to make a request to an external API.
What is From Origin Null?A null origin is another method for enabling global access to website resources, similar to wildcard origin. Null origin, however, permits access to the response if the Access-Control-Allow-Credentials header is set to true, unlike wildcard origin, which does not.
To fix the above error, you can try one of the following solutions:
Make sure that the URL you are trying to fetch is using a supported protocol (e.g. https) and that it is correctly formatted.
If the API you are trying to access supports CORS, make sure that it is configured to allow requests from your domain. This can typically be done by setting the Access-Control-Allow-Origin response header to the origin of your web page.
If the API does not support CORS or you are unable to configure it to allow requests from your domain, you can use a proxy server to make the request on behalf of your web page. This can be done by configuring the fetch API to use a proxy URL instead of the API URL, and setting the no-cors option in the request options.
For more information and detailed instructions on how to fix this error, you can refer to the CORS documentation for React and the fetch API.

Wendy had been searching the internet for a great deal on jewelry. While looking at one site, a pop-up was displayed that told her she had just been chosen as the winner of a nice prize. Being excited to win, Wendy clicked on the link provided to claim her prize. The next day, when Wendy tried to turn on her computer, her computer displayed the Blue Screen of Death (BSOD).
After interviewing Wendy, you suspect that the pop-up she clicked on installed some malicious software that has caused her computer to lock up.
Which of the following is the BEST place to begin repairing Wendy's computer?
Boot the computer from the Windows installation disc and run Startup Repair.
Although BSOD can be caused by many things, given the circumstances and your suspicion that malware may be the cause, you should first isolate Wendy's computer and then try to make her computer bootable by running Startup Repair. Startup Repair attempts to fix problems that keep Windows from loading. If this process fixes her computer, you would then take the proper steps to find and remove the malicious software that caused the issue in the first place.
If the computer does not boot after completing the above, you can try to run a System Restore. This would recover your computer to a previous point, but all of the changes made after the restore point was created would be lost.
If the restore process fails, you could then try to Reset the PC. Keep in mind that this step may get the computer running again, but it will remove all of the applications and settings. If this step does work, you must still check for malicious software that may be disguised as a personal file.
If all else fails, a clean installation of Windows can be performed. And if a backup of Wendy's files are available, they can be restored.
For Wendy to repair the computer, she should continuously hold down the shift key for the Advanced Recovery Options menu to appear. For troubleshooting, she will then click reset the PC. Then select if she can perform a clean install and remove all things or keep the files. Therefore, the correct option is "Boot the computer from the Windows installation disc and run Startup."
Windows Installation and the Run Startup
Select Settings>Update and Security>Recovery from the PC's menu. The page title will be "Reset this PC." Next, click the Get Started option and select keeping files or removing everything.
When using Windows 10, the setting window will be launched by clicking the Start menu, then selecting a gear icon in the low left corner. The other choice from the apps list is the Settings app. Then later, click Update and Security> Recovery in Settings, and decide to Get started under rebooting the PC.
Therefore, booting the computer from the installation disc of the window and running the option of resetting the PC is the best answer.

The statement is true : Both wired and wireless analog signals are particularly susceptible to noise and attenuation and other forms of distortion in a channel because the distortion created cannot be detected and reversed.
An analog signal has a restricted number of possible values within a continuous range that is time-varying and typically limited to a certain range (for example, +12V to -12V). An analog signal, such as electricity flowing over a wire, exploits a specific property of the medium to transmit the signal's information. To represent the information in an electrical signal, the signal's voltage, current, or frequency may be changed. In reaction to changes in light, sound, temperature, position, pressure, or other physical phenomena, analog signals are frequently calculated responses.
Communication systems that employ a continuous signal to transmit voice, data, image, signal, or video information frequently use analog signals. Analog transmission can be divided into two categories that are both based on how data is adjusted to combine an input signal with a carrier signal. Amplitude modulation and frequency modulation are the two methods. Amplitude modulation (AM) modifies the carrier signal's amplitude. FM (frequency modulation) modifies the carrier signal's frequency. There are several ways to produce analog transmission:

Transactions are a set of operations used to perform a set of logical tasks. A transaction typically indicates that the data in the database has changed. One of the primary applications of DBMS is to protect user data from system failures.
ACID Properties:
A transaction is a very small program unit that may contain several low-level tasks. A transaction in a database system must maintain Atomicity, Consistency, Isolation, and Durability, also known as ACID properties, in order to ensure accuracy, completeness, and data integrity.

in this chapter, the class datetype was designed to implement the date in a program, but the member function setdate and the constructor do not check whether the date is valid before storing the date in the member variables. rewrite the definitions of the function setdate and the constructor so that the values for the month, day, and year are checked before storing the date into the member variables. add a member function, isleapyear, to check whether a year is a leap year. moreover, write a test program to test your class.
To rewrite the definitions of the function setDate and the constructor so that the values for the month, day, and year are checked before storing the date into the member variables.
What is a constructor?Constructors are not explicitly called and are only used once during their lifetime. When there is a hierarchy of classes and a derived class inherits from a parent class, the execution sequence of the constructor is a call to the constructor of the parent class first, followed by the constructor of the derived class. Constructors cannot be inherited.
Users are not required to create constructors for every class. Any of the access modifiers can be used to declare a constructor. A constructor with the appropriate access modifier is required.

an access object that provides you with a way to enter, edit, and display data from underlying tables.
an access object that provides you with a way to enter, edit, and display data from underlying table is form.
An Access database can be updated in a number of different ways. When you have a new item to track, like a new contact in the Contacts table, you add a record to your database. At the point when you add another record, Access affixss the record to the furthest limit of the table. In order to remain current, you also update fields, such as adding a new address or last name. To keep up with information trustworthiness, the fields in an Entrance data set will be set to acknowledge a particular kind of information, like text or numbers. Access will display an error message if you do not enter the correct data type. Finally, you can delete a record to free up space and when it no longer serves a purpose. You manually update the data by using a form. Forms for data entry can make entering data faster, easier, and more accurate. Lists, text boxes, and buttons are examples of controls that can be included in a form. Thusly, every one of the controls on the structure either peruses information from or composes information to a hidden table field. Datasheets are data grids that look like worksheets in Excel. By working directly in Datasheet view, you can modify the data. Assuming you are know about Succeed, datasheets ought to be generally straightforward. You can change information in tables, question result sets, and structures that show datasheets. Datasheets are typically used when multiple records need to be viewed simultaneously.
