Please write a C++ program that will keep accepting 3 integer numbers from the user, and output these 3 numbers in order, the sum, and the average of these 3 numbers. You must stop your program when the first number from the user is -777.

Design Specifications and Regulations:

(1) You must use your full name on your Welcome and Thank-you messages.

(2) You must define all the following 5 functions in your program with no exception:

def max (p, q, r) # return the maximum of these 3 integer parameters

def min (p ,q , r) # return the minimum of these 3 integer parameters

def mid (p, q, r) # return the middle of these 3 integer parameters

def sum (p, q, r) # return the sum of these 3 integer parameters

def avg (p, q, r) # return the average of these 3 integer parameters

(3) You must NOT use any existing Python functions in your program.

(4) You must NOT sort those 3 numbers in order to print them in order. You must print them in order by printing minimum, middle, and then maximum.

(5) You must fully test your program to make sure these 5 functions are working perfectly for any data.

test case is as follows:

Welcome to the program of "firstname lastname"!

Enter first number: 9
