Using comments in c explaining how each code works line by line. The whole program is given below. Don't delete anything. For example // #include calls upon the c library #include #define N 16 typedef int fix_matrix[N][N]; /* Set all diagonal elements to a[i] + val */ void fix_set_diag(fix_matrix A, int val) { for( int i=0;i
