Write a C function that takes two arrays of float as parameters. Assume that both of the arrays are of the same size and have been completely initialized. The size of the array should be specified by a third parameter. Your function should return the first position in which the two arrays differ. If the arrays contain identical data, return -1. You should write the function twice.

(a) Write the function assuming that the array parameters are specified using array notation. Use only array notation to access the arrays.

(b) Write the function assuming that the array parameters are specified using pointer notation. Use only pointer notation to access the arrays.
