I want to create the following program in python and c ++ also both programs have to have a function and a main

• create a program that will accept marks (0 to 100) repeatedly from the user

  • you are not sure how many marks the user will enter

• place the values in list

• when the user enters "-1", it sends the list to a function that calculates average and returns it as an integer (rounded off)

example:

lease enter 1 mark at a time. Enter -1 to end. What is your mark? (as 8): 40 What is your mark? (as $): 30 What is your mark? (as $): 10 What is your mark? (as %): 90 What is your mark? (as $): -1 The average is 42%
