The program will print all numbers from the minimum number to a maximum number in a step

of $1.$ The program should have the following functions:

$$ One function to collect and return a number between $1$ and $20.$ If the user enters a wrong

number, the program should ask the user to enter a number again. Name the function as

collect$\_$num$()$

$$ One function, named lowest$\_$num$(),$ to find and return the lowest number between two

numbers. The two numbers are collected using function collect$\_$num$(),$ for example:

int n$1=$ collect$\_$num$()$;

int n$2=$ collect$\_$num$()$;

int minimum $=$ lowest$\_$num$($n$1,$n$2)$;

$$ One function, named highest$\_$num$(),$ to find and return the highest number between

two numbers. The two numbers are collected using function collect$\_$num$(),$ for

example:

int maximum $=$ highest$\_$num$($n$1,$n$2)$;

$$ one function to print all numbers between two numbers. It prints from the lowest to the

highest number, inclusive, in a step of $1.$ This
