Given an integer number

N as input. Write a program to print the hollow right-angled triangular pattern of N lines as shown below.Note: There is a space after each asterisk (*) character.

In the given example the hollow right angled triangle of side

4. Therefore, the output should be   

      *
    * *
  *   *
* * * *

5.Therefore, the output should be

        *

Sum of K powers

Write a program to print the sum of the

Kth power of the first N natural numbers.Input

The first line of input is an integer

N. The second line of input is an integer K.Explanation

In the given example, the sum of first

5 natural numbers power of 3.The sum should be 1³ + 2³ + 3³ + 4³ + 5³

Therefore, the output should be

225.

Product of the Given Numbers

Given an integer

N, write a program which reads N inputs and prints the product of the given input integers.Input

The first line of input is a positive integer,

N. The next N lines each contain an integer.Output

The output should be the product of the given input integers.

Explanation

In the given example,

N = 3 and the input integers are 2, 3, and 7.So, the output should be 2 x 3 x 7 = 42

Product of Numbers from M to N

Given two integers

M, N. Write a program to print the product of numbers in the range M and N (inclusive of M and N).Input

The first line of input is an integer

M. The second line of input is an integer N.Explanation

In the given example, the product of numbers between the range

2 and 5 is 2 * 3 * 4 * 5. Therefore, the output should be 120.

Implement a general Character superclass to simulate what is common to all characters (a) Implement class data fields to support at least the data fields described above about the game character. (b) Implement a constructor method to initialize any class data fields. (c) Include an abstract method to simulate the character using a special skill. The implementation of this method is intended to be ’filled in’ in the subclasses, where the character has a specific nature and skill set

Write a JavaFX program that meets the following requirements(b) Include a graphical control to accept information for each of the following fields: 1) The textual name of the character 2). The textual nature of the character, e.g. ’good’ or ’evil’ .3) A comma separated, textual list of special skills, badges, achievements items or traits the character has. The list may be of length up to 100 characters (a string type)

Write a JavaFX program that meets the following requirements 1) With your demonstration class, Implement a graphical window to display a game character setup dialog to allow the user to enter data into a visible window in order to set up the character object for the game (a) The dialog must provide a separate visual field for each data field, and include a textual label to the left of each field. 

Using the code stub below, output all combinations of character variables a, b, and c, in the order shown below. If a = 'x', b = 'y', and c = 'z', then the output is:xyz xzy yxz yzx zxy zyx

Your code will be tested in three different programs, with a, b, c assigned with 'x', 'y', 'z', then with '#', '$', '%', then with '1', '2', '3’.

#include

using namespace std;

int main() {

char a;

char b;

char c;

cin >> a;

cin >> b;

cin >> c;

/* Your solution goes here */

cout << endl;

return 0;
