Create a program that utilizes functions and loops to determine the most significant digit of a given integer.

The function you create should be named most_significant_digit

This function accepts one parameter, an int which is the number for which you want to find the most significant digit. And the function returns an int which should contain the most significant digit of the function parameter.

Make sure you put the function prototype for most_significant_digit in the header file most_sig_digit.hpp and its implementation in most_sig_digit.cpp. Your program should call this function from within main.cpp. You'll find that skeleton code has already been provided and you simply need to call the function.

Please see the samples below. Note that bold values in the samples represent input by the user.

Please enter an integer, this program will produce it's more significant digit: 4582 The most significant digit is 4

Sample with zero

Please enter an integer, this program will produce it's more significant digit: 0 The most significant digit is 0 

Sample with a negative number

Please enter an integer, this program will produce it's more significant digit: -8382 The most significant digit is -8

This is c++ code. Please make the readable.
