What problems would be solved by moving from virtual machines to containers?

Based on the particle example redo the areashapes assignment to implement the polymorphism concept (via method overloading and overriding) whereby the user selects a shape, and the program calculates, and displays the shape's area using "displayArea()" .

Write a program in assembly language that outputs the leap years between a beginning and an ending year.

1. Initialize $a0 and $a1 with the beginning and ending years.
2. Print out the leap years between 1970 and 2030.

OUTPUT:
From 1970 to 2030:
1972
…
2028

In C++, create a class to hold a set of strings called setTree. setTrees contain copies of the strings inserted so that the strings cannot be changed due to the fact that changing the strings inside the set could break the binary search tree. The strings are case sensitive.

TreeSet implements the following:

bool add(const string& s) -- add s to the set, if it's not already there. Return true if the set changed, false otherwise.

void clear() -- remove all elements from the set

bool contains(const string& s) const -- test whether or not s is in the set.

bool isEmpty() const -- test whether or not the set is empty

bool remove(const string& s) -- remove s from the set, if it was there. Return true if the set changed, false otherwise.

int size() const -- return the number of strings in set.

int toArray(string sa[]) const -- put the elements of the set into the array sa. Assume that sa has sufficient room (it's the client's responsibility to check). You can place the strings in any order you choose.

The class also includes a zero-argument constructor to create an empty set, a constructor that takes in an array of strings and its size (creating a set containing each element of the array), copy constructor, assignment operator, and destructor. The copy constructor and assignment operator make deep copies.

setTree implements the set using a binary search tree. The tree does not need to be balanced. The implementation of the tree node class is hidden from the client. There are no memory leaks.

Create a file named sales_bonus.py

2. Prompt the user for the amount of sales made, convert to a float, and assign to sales.

3. Prompt the user for number of days missed, covert to an int, and assign to days_missed

4. If the user have more than 3000 of sales and has missed less than or equal to two days of work, assign bonus to 100.

5.   Else if the user have more than 3000 of sales or has missed less than or equal to one day of work, assign bonus to 50.

6. Otherwise, assign a bonus of 0.

7. Print out the bonus with two decimal places of precision.

What is the limiting factor in determining how many input/output ports a processor can access?

A: the number of bits allocated to a port instruction

B: the number of bits in the port address

C: the number of bits supported by the data bus D:

the number of bits supported by the address bus

E: There are no limiting factors

What are semi-weak keys for DES? Assume that the first permutation output of an original key to DES is semi-weak. Describe a possible attack against DES encryption? Does this attack significantly reduce the security of DES? Please justify your answer.

Scenario 13‐2: Upgrading a Cluster to Windows Server 2016

As an administrator at the Contoso Corporation, you manage a cluster used as a file server that is running Windows Server 2012 R2. You do not have any other free servers. Describe how to upgrade the cluster to Windows Server 2016.

Write a complete main method that does the following:

Takes any number, but at least two, command line arguments which are words (represented as strings) and will print to the console the number of words of length three. (Hint: loop through the args array)

If there are not at least two command line arguments, throw an IllegalArgumentException with an appropriate message.

For ex: Jenna has a new sister: there are 2 words of length three

public class Question1 {

public static void main (String args[]) {

Use C language

Write a program that reads in a series of lines of input character by character (using getchar()). The first line of the input contains an integer which specifies the number of remaining lines of input, each of which contains a floating point number. The integer value on the first line can be read with scanf(), but all of the following lines can only be read with getchar(). Each line after the first contains a single floating point value, with up to three digits before the decimal point, and up to three digits following the decimal point (but there is not necessarily a decimal point in each number; i.e., it may appear to be an integer, but the digits should be read by your program, and the number should be converted to a corresponding floating point number). For instance, suppose the following input:

5

3.125

20.25

0.875

921.50

31

The required output is:

Each of the input floating point values, printed on a separate line with three digits of precision, using printf();

On the last line of the output, the string “Total:” followed by the sum of the input values, printed with printf() to 3 digits of precision. For example, the total of the sample input given above is 976.750, so the required output for this input would be:

3.125

20.250

0.875

921.500

31.000

Total: 976.750

Do not concern yourself with small differences in the total due to rounding, as the grader will not deduct points for this.

Be sure to include a descriptive message for the user to input the values correctly. You can assume that the user will follow your directions (which should be consistent with the description above), so no exception handling for incorrect input is required. You cannot change the input specifications given above, however.

CONSTRAINTS:

You are not allowed to use arrays on this portion of the lab assignment.

You must use getchar() to read in the floating point values one character at a time (i.e. DO NOT USE scanf()).

-Only use printf() to output the floating point numbers and the total (Do not useputchar()).

Be sure your directions to the user are clear so they are sure to enter the input data correctly.
