The standard QWERTY layout keyboard is called 'QWERTY' because on the top line of the keyboard the first 6 letters from chronological left to right order are; Q, W, E, R, T, and Y.
Or...if you're wondering why it's QWERTY and not ABCDEF, it's because when typing with the alphabetical format, many of the keys would clash with each other due to the arrangement of keys on the original typewriter. The QWERTY layout became so popular, it was the standardized layout for typewriters, and even keyboards today.

Answer:
Option C is the correct answer for the above question
Explanation:
Authentication is used to grant a person to use the system so that no other person can hack the data of the system. It is done by some unique id which is provided to the user of that system. When any person wants to use the system he needs to use that a unique id and sometimes password and some other information to use the system.
The above question asked about the process through which the user of the system grants access to use the system only. So the process is Authentication. hence Option C is correct because it states about the process Authentication while the other is not because--
- Option a states Credibility which is not the process to enter the system.
- Option b states Authorization which is used if the system gives access to the user, not the user can take on its own.
- Option d states Honesty which is not the process to enter the system.
Answer:
previousAddition instance variable
Explanation:
In order to accomplish this you would need to add a previousAddition instance variable. In this variable you would need to save the amount that was added at the end of the process. Therefore, if a mistake were to occur you can simply call the previousAddition variable which would have that amount and subtract it from the total. This would quickly reverse the mistake, and can be easily called from the undo() method.
