Create a simple program in C++ that... 1) Returns the population variance of the given array. Careful that you don't accidentally do integer division.     double getVar (int arr[], int length); 2) Sorts the given array in ascending order     void sortArray (int arr[], int length);

in C++ please

In C++, Let’s assume that we have an array “number” which has the size N=10. Make the program that finds the greatest number between number[0] and number[N/2 - 1] and also between number[N/2] to number[N-1].

Write a C++ program that reads an integer variable named maxAllowed and in output prints all elements less than the value maxAllowed from the array given below. Print -1 if all elements are greater than maxAllowed variable.int Array[10] = {67, 49, 11, 90, 123, 98, 8, 176, 34, 102};

The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below.             The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std;   // Global constants const int ROWS = 3;  // The number of rows in the array const int COLS = 3;  // The number of columns in the array const int MIN = 1;  // The value of the smallest number const int MAX = 9;  // The value of the largest number //…

JAVA Programming Write a function that returns true if you can partition an array into one element and the rest, such that this element is equal to the product of all other elements excluding itself. Examples canPartition ([2, 8, 4, 1]) → true // 8 = 2 x 4 x 1 canPartition ([-1, -10, 1, -2, 20]) → false canPartition ([-1, -20, 5, -1, -2, 2]) true
