Find maximum element of array and swap it with last element of array.

Given an array of N elements. Create a C++ function to count the number of elements of an array with unique notation (that is, the number has different numbers in its writing).

write c code for a function called CountVowels that takes as an input parameter an array of characters and returns the count of all the vowels present in that array. (The maximum length is 200 characters). Use a switch case for this program

Can you please help me write the code in C++? It needs to be exactly wrote like the example in black. Also, if you can include a random number generator between [1,9] for the Matrixes then, that would be great. Note: Use DO-WHILE loop to verify user input for scale factor.

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.
