Assume you have created a two-dimensional array, called names, where all rows have the same number of columns. Which of the following expressions will provide you with the number of columns in the array? names.length O names[1][1].length O None of the other answers are correct. O names.length.length O names[1].length

Please chose the right option.

Array a is an integer array with all the elements in ascending order. The element at position 15 is the 15th largest and also the 15th smallest. You can assume integers are 4 bytes long. How many bytes are there in the array? O 116 124 O None of the other answers is correct. 120

1. What is an array? Is there a difference between a variable vs array? What is an off by one error? 2. Look at the following pseudocode:   constant integer SIZE = 3   Declare integer numbers[SIZE] = 1, 2, 3     a. What value is stored in numbers[2]?     b. What value is stored in numbers[0]?

Which of the following lines of code returns an error? A numpy.array (x) B) none of these (C) np.array (x) (D) array (x)

Program: Using a multidimensional array, create a triangular-shaped array. You will ask the user how many lines they want to see and then create the array, fill it, and then print it. You will fill the array with one 1 in the first row, two 2’s in the second row, etc. This should work for any integer that the user enters. (Just because I am starting on 1 does not mean row 0 was skipped.)   You must: use a loop to create the array shape. You must: use nested for loops to fill the array and to print the values back to the screen. Your program should print as shown below.   Example Output:   How many lines would you like in your triangle? >>>9 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9   If your code looks like the code below, it is not what I’m asking for. The code below is making a square multidimensional array, not a triangular one. The code below is just leaving certain spots empty so that it looks like a triangle. I will ask you…

Please write a program to find the following values form the array:int a[] = {20, 34, 18, 9, 43, 22, 16, 45}; The sum value of the array The average value The maximum value of the array The minimum value of the array

Which statement declares a two-dimensional integer array called myArray with 3 rows and 4 columns?     a.   intmyArray[3,4];     b.   int[]myArray=newint[7];     c.   int[][]myArray=newint[3][4];     d.   int[]myArray=newint[4][3];     JAVA

Code to how do you total all of the matching integer elements in an array?.  ASAP.

Using Java Write an app that allow data entry into an array. 1 Ask the user how many numbers they want to add. 2 Allocate an array of doubles to the specified size. 3 Prompt the user for the numbers to populate the array. 4 Calculate the total and the average of the values.
