Write a program in C++ that lets the user enter a product code. The program should determine if the product code is valid by checking for it in the following list: 65482 15975 48758 58698 69618 78965 68416 26489 35498 91651 The codes should be initialized into an array. A simple linear search should be used to locate the code entered by the user. If the user enters a code that is in the array, the program should display a validation message. If the user enters a code that is not in the array, it should display an error message.

In C++: Write a program which will prompt the user to enter an array of 12 characters. The program should then print the array, and then print the array again, but this time as a 4 colums by 3 rows array.

In statistics, the mode of a set of values is the value that occurs most often or with the greatestfrequency. Write a function that accepts as arguments the following:A. An array of integersB. An integer that indicates the number of elements in the arrayThe function should determine the mode of the array. That is, it should determine which valuein the array occurs most often. The mode is the value the function should return. If the arrayhas no mode (none of the values occur more than once), the function should return −1.Demonstrate your pointer process by using pointer notation instead of array notation in thisfunction.

Write a C++ program that uses a 1D array to store 25 students' computer programming grades (total grade 100). The program should not accept incorrect or invalid grades, and the user should be able to enter marks one at a time. Once the user has completed the entry, the program should output the following. a) Maximum grade b) The average grade (sum of all grades/total number of students) c) Minimum grade Write the C++ code in the space provided (Full marks are awarded for a complete solution.)

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()

In c++ The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown in Figure. The Lo ShuMagic Square has the following properties:• The grid contains the numbers 1 through 9 exactly• The sum of each row, each column, and each diagonal all add up to the same number.In a program you can simulate a magic square using a two-dimensional array. Write a functionthat accepts a two-dimensional array as an argument, and determines whether the array is a LoShu Magic Square. Test the function in a program.

Write a C++ program that initializes an array of size 10 with 10 integer values between 1and 100. The program then asks the user to enter an integer number between 1 and 100. Theprogram will search the entered number in the array, if it is present the program displays itsindex in the array otherwise program displays "element not found" message.

Write a function that determines the average of the values in an array. In the main() function declare a floating point array with a length of 8 elements, and have the user enter the value of each element using a loop. The program should then call and pass the array to the function, then display the average.

c++ A lottery ticket buyer purchases 10 tickets a week, always playing the same 10 5-digit "lucky" combinations. Write a program that initializes an array or a vector with these numbers and then lets the player enter this week’s winning 5-digit number. The program should perform a linear search through the list of the player’s numbers and report whether or not one of the tickets is a winner this week. Here are the numbers: 13579 26791 26792 33445 55555 62483 77777 79422 85647 93121 If the user enters a number that is not in the array, the program should display a message indicating that the number is invalid.

in C++: SummaryJason, Samantha, Ravi, Sheila, and Ankit are preparing for an upcoming marathon. Each day of the week, they run a certain number of miles and write them into a notebook. At the end of the week, they would like to know the number of miles run each day and average miles run each day.InstructionsWrite a program to help them analyze their data. Your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. Furthermore, your program must contain at least the following functions: a function to read and store the runners’ names and the numbers of miles run each day; a function to calculate the average number of miles run each day; and a function to output the results. (You may assume that the input data is stored in a file and each line of data is in the following form: runnerName milesDay1 milesDay2 milesDay3 milesDay4 milesDay5 milesDay6...

For C++: Design an application that has an array of at least 20 integers. It should call a module that uses the sequential search algorithm to locate one of the values. The module should keep a count of the number of comparisons it makes until it finds the value. Then the program should call another module that uses the binary search algorithm to locate the same value. It should also keep a count of the number of comparisons it makes. Display these values on the screen.
