Matrices In this exercise you will write several functions t

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.h with their definitions in a source file named matrix.c. You should test your functions by writing a driver program, but you need not hand it in. Write a function that takes two matrices and determines if the sum of all of the elements in matrix A is equal to the sum of all the elements in matrix B. Return 0 if the summation is equal and 1 if they are not equal. int sum Equal(int**A, int **B, int n); Write a function that takes two matrices and determines if they are equal (all of their elements are the same). If the matrices are equal, return 0. Return I if they are not equal. int is Equal(int **A, int **B, int n); Write a function to compute the sum of the elements along the diagonal of the matrix. Return the sum of the elements along the diagonal. int diagonal (int **A, int n); Write a function to compute the summation of matrix A and B. int.** surnMatrix(int. **A, int **B, int n); The product of two square n times n matrices: C = A times B The entries for C are: C_ij = sigma^n_k = 1 a_ikb_kj where 1 lessthanorequalto i, j lessthanorequalto n and is the (i, j)-th entry of the matrix C. Write the following function to compute the product of two n times n square matrices: int ** product(int **A, int **B, int n); Bonus Name the files, bonus.c and bonus.h char highestFreq(char *str)- this function should return the highest frequency character c in the string. For example, a call to this function with the string \"Hello World\", would return \"1\"
