3. Removе an el nt fror an Consider an array named source. Write a method/function named remove( source, size, idx) that removes the element in index idx of the source array. You must execute the method by passing an array, its size and the idx( that is the index of the element to be removed). After calling the method, print the array to show whether the element of that particular index has been removed properly. Example: source=[10,20,30,40,50,0,0] remove(source,5,2) After calling remove(source,5,2), printing the array should give the output as: [ 10.20.40.50.0.0.01 Use Python language

QUESTION 2 Write the overloaded method named findvAverage () for each of the following problems: a) The first method receives two integer numbers and returns the average of these two numbers b) The second method receives an array of integer numbers. Calculate and display the average of those elements in array.
Problem: We need a program that takes 8 products and makes calculations and informs the user. Products have name, type and cost. Write the program that takes name,type and cost information from the user and saves the product objects to an array and calculates the total cost, the one with the most cost and the one with the least cost. For example: Banana Fruit 10 Apple Fruit Trousers Textile 50 T-Shirt Textile 30 Pencil Office 15 Office Раper Strawberry Computer 10 Fruit 20 Electronics 6000 Total Cost: 6140 TL Most Expensive: Computer Least Expensive: Apple
QUESTION 23 Cl. Write a Java program named Transform that generates a single-dimensional array of and fill the array with 12 random integer numbers (numbers' range: between 0 and 9 inclusive). The program should display the array elements. Then it should triple the value of each number in the array and display the new tripled values. A sample run of the program: The array's elements are: 2018 3678 7 4 8 2 The new tripled values are: 6 0 3 24 9 18 21 24 21 12 24 6
Create a function named "onlyOdd".The function should accept a parameter named "numberArray".Use the higher order function filter() to create a new array that only containsthe odd numbers. Return the new array.// Use this array to test your function:const testingArray = [1, 2, 4, 17, 19, 20, 21];

You are working for a university to maintain a list of grades and some related statistics for a student. Class and Data members: Create a class called Student that stores a student’s grades (integers) in a vector (do not use an array). The class should have data members that store a student’s name and the course for which the grades are earned. Constructor(s): The class should have a 2-argument constructor that receives the student’s name and course as parameters and sets the appropriate data members to these values. Member Functions: The class should have functions as follows: Member functions to set and get the student’s name and course variables. A member function that adds a single grade to the vector. Only positive grades are allowed. Call this function AddGrade. A member function to sort the vector in ascending order. A member function to compute the average (x̄) of the grades in the vector. The formula for calculating an average is x̄ = ∑xi / n where xi is the value of each…
Problem 11 of an Create a class ArraysAndMethodsGames, Write a method that returns the average array with the following header: public static double average(double[] array); Write a method to initialize the array with the following header: public static double[] readArray(): The readArray method prompts the user to enter ten double values and initializes a newly array with these values. It returns the array to main. The method main calls the method Method main prints the array as well. created average and prints the average. 8 Of 9 – SLCC, ASDV 1220, Lab17 Problem 12 Modify class ArraysAndMethodsGames by adding a method that finds the smallest element in an array of double values using the following header: public static double min(double[] array); Call it from main to test it with an array you create in main.
In this assignment, you will decide how to keep the inventory in the text file. Then your program must read the inventory from the file into the array. Each product must have a record in the file with the name, regular price, and type. There are several options for storing records in the file. For example, • each value takes one line in the file (i.e., three lines for one product). Then you must take care of correct handling of the ends of the lines; • all values are in one line that can be read as a string. Then you must handle the parsing of the string; • all values are in one line separated by a delimiter. Then you must handle a line with delimiters. Assume that the inventory does not have more than 100 products. But the actual number is known only after the reading of the file. Once you can read data from the file into the array, you must add a new property to the product class – a static variable that holds the number of products in the inventory. Its value must grow as reading…
What transpires when a parameter for an array is sent in with either the ref or out keyword, and the results are observed?
1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.
Given an integer array of positive single digit values such as:int a[] = {8,4,2,6,9};1) Write a recursive arrayToN function which returns the concatenation of all array values as an integer value.This function should accept all required data as parameters and return a long integer value.ExamplesIf the array is 8 4 2 6 9 the arrayToN function returns the integer 84269.If the array is 0 2 6 8 9 3 5 1 the arrayToN function returns the integer 2689351.
