Program 1 - Range of a set of numbers numbersFor this program, you need to read in 3 numbers, order the numbers in ascending order, and calculate thedifference between the largest and smallest number entered. Call this filerange.cpp1. Prompt the user and read in 3 numbers. Store them in 3 variables. (8 points)2. If the user entered the same number 3 times, print an error message and exit. (7 points)3. Useif ...elsestatements, in whatever combination required, to print the numbers out in ascendingorder. (25 points)4. Print the difference between the largest and smallest number. (5 points)5. Add comments wherever appropriate to explain your logic. (5 points)6. You can assume that the user will only enter the proper type of data for the 3 numbers. No typechecking required.Sample RunsThe underlinedtext is the user input.
