Matrices In this exercise you will write several functions that operate on matrices or two-dimensional arrays. For this exercise, we will restrict our attention to square matrices-collections of numbers with the same number of columns and rows. You will place all the function prototypes in a header file named matrix_utils.h with their definitions in a source file named matrix_utils.c. You should test your functions by writing a driver program, but you need not hand it in. (a) Write a function that constructs a new n n identity matric. An identity matrix is a square matrix with ones on the diagonal and zeros everywhere else int **getIdentityMatrix(int n); b) Write a function that takes two matrices and determines if they are equal (all of their elements are the same int isEqual (int **A, int **B, int n); c) Write a function that takes a matrix and an index i and returns a new array that
