Question
Your input to a function is an array with length N named inArray. Assuming that N is a variable created within your function using the length command, which of the following would be an appropriate way to preallocate an output of length 2*N?
out = 2*inArray;
out = zeros(2,N);
out = length(2*N);
out = ones(2*N,1);

- • • Asks the user for their name and store it in an array Asks the user for their age and store it in a variable Determines how many years before they can retire at age 67. If user is 67 then it will indicate that the user should retire now. If user is over 67 it will indicate that the user should have already retired If the user is under 67 then it will indicate number of years before retirement Ends with a thank you message. Example of Output Welcome to nameage Please enter name: (user enters a value like Pat) Please enter your age: (user enters a value like 69) Hi Pat. You should already be retired. Thank you for using nameage.

- Create Array of Random Dates In this task you are required to write a function that will generate a column array (a variable called dates) containing N random dates. N is an integer (whole number) entered by the user and will indicate to the function how many random dates the user requires. The dates array will be structured as follows: • The array shall have two columns; column 1 will contain numbers indicating the day of each month (1-31) and column 2 will contain numbers indicating the month (Jan 1, Feb=2, Mar = 3.... Dec = 12). . Each day must be randomly generated (using the randi() function) taking into account the maximum number of days in each month (i.e. Jan, Mar, May, Jul, Aug. Oct and Dec have 31 days, Apr. Jun, Sep and Nov have 30 days and Feb will have 28 days). You must use an if-elseif-else statement to decide this. • We are assuming no leap years (e. February can only have days between 1-28). For example, the output from calling the function: output = dategen (3) could…arrow_forwardCreate a function named "onlyOdd".The function should accept a parameter named "numberArray".Use the higher order function filter() to create a new array that only containsthe odd numbers. Return the new array.// Use this array to test your function:const testingArray = [1, 2, 4, 17, 19, 20, 21];arrow_forwardWrite a function named swapFrontback that takes as input an array ofintegers and an integer that specifies how many entries are in the array. Thefunction should swap the first element in the array with the last elements inthe array. The function should check if the array is empty to prevent errors.The header file for the swapFrontback() is:swapFrontback.h:double swapFrontback (int [] arr,int size);Write a driver (main.c) to test your function with arrays of different lengthand with varrying front and back numbers. Print the array elements beforeand after the swap in the main.c.Sample Run: Original Array: 1 2 3 4 5 6 FrontBack Array: 6 2 3 4 5 1arrow_forward
- Write a function named rockPaperScissors. It should have one input:- An array with 2 elements, each representing a player in the game of Rock Paper Scissors.It should return one output- A scalar with the result of the game.For the purposes of this program, assume the following numerical code:- 1 is rock- 2 is paper- 3 is scissorsIn the game of Rock, Paper, Scissors, rock beats scissors, paper beats rock, and scissors bears paper. Ifplayers play the same object, the result is a tie.Your output should be:- The index of the winning player if there is a winner.- 0 if there is a tie- -1 if a player played an invalid object (a number that is not 1, 2, or 3)For example, if we called our function:result = rockPaperScissors([1 2]);result would be 2, as paper beats rock.If we called our functionresult = rockPaperScissors([3 2]);result would be 1 because scissors beats papearrow_forwardProblem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9arrow_forwardPrompt: In Python language, write a function that applies the logistic sigmoid function to all elements of a NumPy array. Code: import numpy as np import math import matplotlib.pyplot as plt import pandas as pd def sigmoid(inputArray): modifiedArray = np.zeros(len(inputArray)) #YOUR CODE HERE: return(modifiedArray) def test(): inputs = np.arange(-100, 100, 0.5) outputs = sigmoid(inputs) plt.figure(1) plt.plot(inputs) plt.title('Input') plt.xlabel('Index') plt.ylabel('Value') plt.show() plt.figure(2) plt.plot(outputs,'Black') plt.title('Output') plt.xlabel('Index') plt.ylabel('Value') plt.show() test()arrow_forward
- Write a function that determines the average of the values in an array. In the main() function declare a floating point array with a length of 8 elements, and have the user enter the value of each element using a loop. The program should then call and pass the array to the function, then display the average.arrow_forwardCreate a program called array.py that has a function that takes four integer arguments. Those arguments should be put into an Numpy array. The function will have two print statements. The first will print the type of the array you create (which should be <class ‘numpy.ndarray’>). The second will print the multiplication of the four items in your array.arrow_forwardI want to make a program about a cafe business The idea is to have a txt file for a menu and operate all the functions in it.arrow_forward
