can someone help me with this in C++ Given the following input: Array size (positive integer value) Array elements (positive integer values) Write a program that prints whether the array is a palindrome number. A palindrome number is a number that reads the same backwards and forwards. You must implement your solution following the requirements below: a) Do not use cout to print a message before reading the input from STDIN. b) Read the input in the main function. c) Implement a function to print whether all the elements of the array form a palindrome number. You must use a pointer to an integer variable to implement your function. You cannot use square brackets (array notation) inside the function. You can assume that the input will always be valid.

7. Write a function that evaluates the area of a pentagon. Use "math.pi", for pi, and "math.sqrt" for square root. Write the solution on the space provided below. You do not need to run the code. DII 3.2 (Geometry: area of a pentagon) Write a program that prompts the user to enter the length from the center of a pentagon to a vertex and computes the area of the pen- tagon, as shown in the following figure. 3√3 2 The formula for computing the area of a pentagon is Area -s², where s is TT the length of a side. The side can be computed using the formula s = 2r sin 5 = where r is the length from the center of a pentagon to a vertex. Here is a sample run:

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…
