C++ Programming. OVERVIEW OF DATA STRUCTURES. Task: Write a program to process a data array. Execute a custom task as a separate function or method of a custom class. When performing a task, use functional methods for manually entering array elements, generating random numbers, and printing array elements. Given an array of size N. Create a function to determine the element that is furthest from the arithmetic mean of the array elements (that is, the maximum absolute difference).
Please complete the following guidelines and hints. Using C language.

TRUE OR FALSE, C++ When passing an array to a function, you must include & in front of the array name. When passing an array to a function, you must include & in front of the array name. It is possible to have a 2-dimensional array where each row has a different number of columns. The * is called the address of operator.
help me solve this in c++ please Write a program that asks the user to enter a list of numbers from 1 to 9 in random order, creates and displays the corresponding 3 by 3 square, and determines whether the resulting square is a Lo Shu Magic Square. Notes Create the square by filling the numbers entered from left to right, top to bottom. Input validation - Do not accept numbers outside the range. Do not accept repeats. Must use two-dimensional arrays in the implementation. Functional decomposition — Program should rely on functions that are consistent with the algorithm.
C++ A matrix is a rectangular array of numbers that is arranged in a two-dimensional table. Matrices have numerous applications in computer systems. Matrix structures are examined in computer memory, graphics, and cryptography. The Hill cipher, for example, makes use of matrix inversions to encrypt and decrypt data. The intent of this problem is to develop a C++ program that computes and displays the inversion of a 2 x 2 matrix. A matrix is said to have the dimensions m x n if it has m rows and n columns. A square matrix has the same number of rows as columns, and is therefore said to have m x m dimensions. Matrix M shown below is an example of a 2 x 2 matrix. The inverse of a square matrix, M-1, is defined by the equation M(M-1) = I, where I is called the identity matrix. I is a square matrix that is all zeros except for ones along the main diagonal from the upper left corner to the lower right corner. I for a 2 x 2 matrix is: Multiplying a square matrix by its inverse will always…
