Given two character arrays: char s1[10] = "chararray", s2[10];, which lines will successfully copy the string from s1 to s2. (multiple choice) - s2 = s1; - strcpy(s2,s1); - both - neither

Initialize two integer arrays, a[6] and b[6]. First print their elements in two rows, and then print them out in two columns. : Initialize the arrays with random integers in the range between 0 & 20, inclusive

What’s the difference between an array and Vector?

pArray is a pointer to an array of doublewords, therefore declare it as a local variable called pArray.

Which of the following statement will display elements of the array in one line at a time? ​ char myArray[4] = {'a', 'b', 'c', 'd'};  for (int i = 0; i < 4; i += 1)    ---- code goes here ----         ​​cout >> myArray >> endl;         ​​cout >> myArray[i] >> endl;         ​cout << myArray[i] << endl;         ​​cout << myArray[4] << endl;

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()

Write code that creates an array of 9 string elements and initialises them to empty.

It is the value that is automatically assigned to the remaining elements of the array when the initialize list is less than the size. Select one: O a. 0 O b. \1 0 с. 10 O d. 1

Choo se the best C++ code segment that: 1. Counts the number of space character (') in the array. 2. Replaces each character in even index in the array with the '# character. char T[10] = {'$',' ','1','R','5',7',X','2','@,' '}; int count=0; for (int i-0;i<10;i++) a) if (T[)=') count++; for (int i-0;i<10;i=i+2) T[]=#; char T[10] = {'$'; ',1',"R',5',7',X',"2',@, }; int count=0; for (int i-0;i<10;i++) { b) if (T[]=) count++; if ((i%2)=0) T[i)=#; } char T[10] = {'$'; ','1','R','5',7','X','2','@,' '}; int count=0; for (int i-0;i<10;i++) { if ((i% 2)=0) c) T[]=#; if (T[]=) count++; char T[10] = {'$'; ','1','R',"5',7',X','2','@', '}; int count-0; int k=0; for (int i-0;i<10;i=i+2) { d) T[i)=#; if (T[k]==') count++; if (T[k++]=) count++; e) a) and d) d)

Question4: Write a Java program to calculate the sum & average value of array elements.
