A python function opens file data.csv, reads the data from the file and spits the data into three columns, x, y and z. The data is then printed out. Function: f = open("data.csv ", "r") print('x\ty\tz'.format()) for row in f:     temp = row.split(',')     for cell in temp:         print(cell,end='\t')     print()   data.csv contains: 1.2,2.1,1.1 2.3,3.2,0.6 0.7,1.9,0.1 1.8,2.5,0.3 4.6,2.7,0.9

Prompt: 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()

Which of the following are true? O The C-library has many functions that are useful in manipulating strings. V If a and b are two different C-string variables, the value in a can be assigned the value in b with the following C-statement: a = b; %3D O The length of the char array holding the string must be at least one character longer than the string itself. O An array identifier cannot be used as a pointer. V The identifier, name, of a C-string is also a pointer to a char data type. The ending character in a C-string must be the newline character, '\n'. O The name of a 1-D array is a pointer to the data type of the array, while the name of a 2-D array is a pointer to a 1-D array of the data type.
