Write a program to read an array 7x7 , (choose your own numbers ) and write a function to return the maximum number and sum of odd numbers.

Write a function which will find the average of all elements of an array of integers. Pass an array anda dimension (the number of elements), and return the value of the average as a float ( the return value).Test this function in the main program with the array: 5, 7, 3, 5, 6, 4. c++

Note: It`s C++

Imagine that you are a biomedical engineer analyzing DNA sequences. You have numerical measurements from two different measurement sources, m1 and m2, both of which are arrays. Write a function named dna that takes these two arrays as inputs. It should return a character array string of nucleotides (represented by the letters A, C, G and T). For a given index, i, the nucleotide in the string is: - ‘A’ if m1(i) >= 0 and m2(i) >= 0 - ‘C’ if m1(i) < 0 and m2(i) >= 0 - ‘G’ if m1(i) >= 0 and m2(i) < 0 - ‘T’ if m1(i) < 0 and m2(i) < 0    code to call the function  m1 = [-2 -3 2.5 0.3]; m2 = [1.1 2.1 -0.8 0.1]; sequecne = dna(m1,m2);  function dna    Please use MATLAB
