Question
Chapter 4, Problem 5PWE
Program Plan Intro
To prompt the output to input the three floating values and print their average.
The program should be detailed for the user.
Program Description:
To input the three floating values, three float variables (f1, f2, and f3) are declared.
The sum and the average of the floating values must be floating, so the variables sum and avg are declared as a float.
Then, the values of the variables are inputted, then the average is calculated in the variable avg.

In this variable, the number of source-level statements and the number of I/O operations are both kept track of.
5.20 LAB: Step counter
A pedometer treats walking 2,000 steps as walking 1 mile. Write a program whose input is the number of steps, and whose output is the miles walked.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('{:.2f}'.format(your_value))
Calculate the average of the variables
a
,
b
, and
c
, and assign the result to a variable named
avg
. Assume that the variables
a
,
b
, and
c
have already been assigned a value, but do not assume that the values are all floating-point. Make sure the value that you assign to
avg
is a floating-point value.
