(C++) Using passing by value or by reference, create the following four functions/procedures:

void displayMenu();

int largest(int a, int b, int c);

void mySort(int& a, int& b, int& c);

void myPermutation(int& a, int& b, int& c);

where displayMenu prints a list of options to the console, largest returns the largest value among three input integers, mySort sorts the three integers in ascending order, and myPermutation applies a permutation to the numbers (that is, a list of numbers 1 2 3 will become 2 3 1 after the function call).

Your main function should take in three integers from the user, and then continuously display a menu of options and call the corresponding function based on the user input until the user enters Q.

Instructions: You may assume that the user always provides valid input. You may not use stdafx.h. Include header comments and function comments. You may not use any library other than .

ple run of your code may look like ode may look Iike: Enter your three integer numbers: 4 MENU 1. Output the largest 2. Get the next permutation 3. Sort in ascending order Enter your choice (1 - 3), Q to quit: 1 The largest number among the three is: 5 =MENU 1. Output the largest 2. Get the next permutation 3. Sort in ascending order Enter your choice (1 - 3), to quit: 3 After sorting: 3 4 5
