HW 7
Due 03/01:
  • Write a program that reads in 14 numbers from the user (from keyboard), and outputs:
    - the sum of all negative numbers,
    - the sum of all positive numbers,
    - the number of zeros,
    - the average of positive numbers,
    - the average of negative numbers,
    - the average of all numbers.
    Use exception handling for the cases when an letter of a string is provided instead of a number. In such a case just terminate the program.
    Don't forget to comment your program!

    Hints : (use for loop; count negative numbers and positive numbers),
    at each iteration take the next inputted number
    if it is negative - add it to the sum of all negative numbers, increment the counter of negative numbers
    if it is positive - add it to the sum of all positive numbers, increment the counter of positive numbers
    if it is zero, increment the counter for the zeros,
    When the loop is over, you'll have a sum of all negative numbers, and the sum of all positive numbers, along with the numbers of negative and positive numbers, and the number of zeros. So you'll know how to find the averages.

    Here is a grading rubric for this exercise:
    - the sum of all negative numbers is found correctly ( 1 point ),
    - the sum of all positive numbers is found correctly ( 1 point ),
    - the number of zeros is found correctly ( 1 point ),
    - the average of positive numbers is found correctly ( 1 point ),
    - the average of negative numbers is found correctly ( 1 point ),
    - the average of all numbers is found correctly ( 1 point ),
    - exception handling is used and is used properly ( 2 points ),
    - comments are present and they are meaningful( 1 point ),
    - clear input/output messages ( 1 point )

  • Write three different programs that find the maximum of three numbers. The user will input the numbers from the keyboard. You can choose three from four: each to all , decision tree method , sequential processing and Pythons built-in function max .
