Given an array arr, of type int, along with two int variables i and j, write some code that swaps the values of arr[i] and arr[j

Inessa05 [86]

You'll need a helper variable for this, so depending on your programming language, the solution becomes:

int helper;

helper = arr[i];

arr[i] = arr[j];

arr[j] = helper;

Write a program that accepts three decimal numbers as input and outputs their sum

Sophie [7]

Answer:

sum = 0.0

for i in range(0,3):

sum += float(input("Enter a decimal number to sum: "))

print ("Sum: ", sum)

*** Sample Input ***

Enter a decimal number to sum: 1.1

Enter a decimal number to sum: 2.2

Enter a decimal number to sum: 3.3

*** Sample Output ***

Sum: 6.6

Explanation:

For this problem, a method was devised in python to create the sum of three individual decimal numbers.

The first line of code, sum = 0.0, initializes a variable to the float type in which we will store the value of our sum. Note, it is initialized to 0.0 to start from a value of 0 and be considered a float.

The second line of code, for i in range(0,3): is the creation of a for loop control structure. This will allow us to repeat a process 3 amount of times using the iterator i, from value 0 to 3 in this case. Note, 0 is inclusive and 3 is exclusive in the python range. This means the for loop will iterate with, i=0, i=1, and i=2.

The third line of code, sum += float(input("Enter a decimal number to sum: ")) is simply asking the user for a number, taking that input and converting it from a string into a float, and then summing the value with the previous value of sum and saving that into sum.

The fourth line of code, print ("Sum: ", sum) is simply displaying the final value that was calculated by adding the three user inputs together which were stored into the variable sum.

Cheers.

Which method adds 10 to the right end of the array? myArray. insert (10)

vladimir1956 [14]

JavaScript has a set of mutator functions that allow you to modify the contents of an array without referencing the individual elements.To add to to myArray we us the push() method

<h3>Adding Elements to an Array</h3>

To add to to myArray we us the push() method

(10)

myArray.push(10)

There are two mutator functions for adding elements to an array: push() and unshift(). The push() function adds an element to the end of an array:

var nums = [1,2,3,4,5]; print(nums); // 1,2,3,4,5 nums.push(6);

print(nums); // 1,2,3,4,5,6

var nums = [1,2,3,4,5]; print(nums); // 1,2,3,4,5 nums[nums.length] = 6; print(nums); // 1,2,3,4,5,6
