Answer:
O(N!), O(2N), O(N2), O(N), O(logN)
Explanation:
N! grows faster than any exponential functions, leave alone polynomials and logarithm. so O( N! ) would be slowest.
2^N would be bigger than N². Any exponential functions are slower than polynomial. So O( 2^N ) is next slowest.
Rest of them should be easier.
N² is slower than N and N is slower than logN as you can check in a graphing calculator.
NOTE: It is just nitpick but big-Oh is not necessary about speed / running time ( many programmers treat it like that anyway ) but rather how the time taken for an algorithm increase as the size of the input increases. Subtle difference.
The correct answer is that Dante did not click the Save and Close button before exiting the appointment.
When you make a change to an appointment in the Outlook calendar you need to click on Save in order to have the change saved in your calendar. If you do not do this the appointment will revert back to the original time and date when you exit the program.
Answer:
Point A: Always True
Point B: Sometimes false
Point C: Always False
Explanation:
In the given code snippet. Point A is the first statement within the While loop the statement System.out.println("Welcome to Java!"); will only be executed if the while condition evaluates to true.
At Point B, The statement count++ increases the value of the counter at every iteration, while it will be true for most occasions, at the last increament, this statement will be false that is at count=100, The condition will be false at this point just before program execution breaks out of the loop
Point C is outside of the loop, this happens when the given condition is no longer true.

Answer:
ofstream asia("asiasales2009.txt"); //It is used to open asiasales2009.txt files with the asia objects.
ofstream europe("europesales2009.txt"); //It is used to open europesales2009.txt files with the europe objects.
ofstream africa("africasales2009.txt");
//It is used to open africasales2009.txt files with the africa objects.
ofstream latin("latinamericasales2009.txt");//It is used to open latinamericasales2009.txt files with the latin objects.
Explanation:
- The above code is written in the c++ language which is used to open the specified files with the specified objects by the help of ofstream class as described in the question-statements.
- The ofstream is used to open the file in the c++ programing language, so when a user wants to use the ofstream to open the file in written mode, then he needs to follow the below syntax--
ofstream object("file_name_with_extension");
