- (Statistics) Write a program that includes two functions named calcavg() and variance(). The calcavg() function should calculate and return the average of values stored in an array named testvals. The array should be declared in main() and include the values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, and 73. The variance() function should calculate and return the variance of the data. The variance is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calcavg() and variance() should be displayed by using cout statements in main().(Electrical eng.) Write a program that stores the following resistance values in an array named resistance: 16, 27, 39, 56, and 81. Your program should also create two arrays named current and power, each capable of storing five double-precision numbers. Using a for loop nd a cin statement, have your program accept five user-input numbers in the current array when the program is run. Your program should store the product of the values of the squares of the current array and the resistance array in the power array. For example, use power[1]=resistance[1]pow(current[1],2). Your program should then display the following output (fill in the chart):1. a Which of the below correctly calls a function named “foo”, passing it an array named “nums” of 5 ints? Group of answer choices foo(nums[5]); foo(nums); foo(int nums[5]); foo(nums[]); b The best way to print a two dimensional array is to use a: Group of answer choices for loop in a for loop for loop followed by another for loop while loop in a do-while loop None of the above c Which of the following correctly declares a vector of floats named “nums”? Group of answer choices vector nums<float>; float vector(nums); vector nums(float); vector<float> nums; d int *num_ptr; int y = 100; int x = 0; Which of the following statements correctly points num_ptr to x? Group of answer choices *num_ptr = x; *num_ptr = &x; num_ptr = &x; num_ptr = x; all part solution
- In this assignment, you will create three arrays of size 8; one array will be an integerarray, one will be a char array, and one will be a float array. You will then ask the userto state what kind of data they want to sort – integers, chars, or floats.The user will then input 8 values. You will store them in the appropriate array based onwhat datatype they initially stated they would use.You will create a function called sortArray() that takes in an integer array as aparameter, and two overloaded versions of the same function that take in a char arrayand float array as parameters respectively. You will use these functions to sort theappropriate array and display the sorted values to the user.Note: You must make overloaded functions for this assignment – they must all be calledsortArray(). You can not create unique, non-overloaded functions like sortArrayChars().Sample Output #1:[Overloaded Sort]What data type do you want to enter? floatValue 1: 3.4Value 2: -1.0Value 3: 2.0Value 4:…Code two functions to fill an array with the names of every World Series winning team from 1903 to 2020, then output each World Series winner and the number of times the team won the championship.

- Write a function named 'dynamicRotate (num)'. When invoked, the `dynamicRotate' function will accept a number to be used as the rotation amount and return a function. Positive numbers rotate the array to the right and negative numbers rotate to the left. The function returned by 'dynamicRotate' will accept an array to be rotated by the amount provided when 'dynamicRotate' was first invoked. It will return the original array mutated by the given rotation. Examples: ' ' ' js let arr - ['a', 'b', 'c', 'd', 'e']; rotateRightTwo = dynamicRotate (2); rotateRightTwo (arr); console.log(arr); // [ 'd', 'e', 'b', 'e' ]; let animals = ['wombat', 'koala', 'opossum', "kangaroo']; rotateLeftone = dynamicRotate(-1);rotateLeftOne (animals) console.log(animals); // [ 'koala', 'opossum, "kangaroo', 'wombat"]' ' '***************? function dynamicRotate(num) { // Your code here } /*****DO NOT MODIFY ANYTHING UNDER THIS LINE*****/ try { module.exports = dynamicRotate; } catch {…For this programming exercise you will use the text file named “USPopulation.txt” that is located on Blackboard in the same location as these instructions. The file contains the midyear population of the United States, in thousands, during the years 1950 through 2000. The first line in the file contains the population for 1950, the second line contains the population for 1951, and so forth. Write a program that reads the contents of the file into an array. The program should display the following information: • The average annual change in population during the time period. • The year with the greatest increase in population during the time period. • The year with the smallest increase in population during the time period.he data must be stored in two dynamic arrays: an array of strings named names, and an array of ints named scores. These arrays must be declared and allocated using "new" in the main function. The user input of the names and scores should be done in a function named readData(). It should have the following signature: void readData(string names[], int scores[], int size) You must also write two more functions: one to sort both arrays in descending order by score, and one to display the final list of names and scores. They should have the following signatures. void sortData(string names[], int scores[], int size) void displayData(const string names[], const int scores[], int size) The main function should be very short. It should just get the number of scores, allocate the two arrays, invoke these three functions, and then deallocate the arrays. Some of you may not have studied sorting algorithms. Sorting is covered in lesson 9, section 9.6. You can copy as much code from that lesson as…
