Question

1. When breaking a problem down, you often encounter elements that you want to use repeatedly in your code. Sometimes it's appropriate to write a new function; at other times it's appropriate to write a loop.

What do you think? What kinds of circumstances would lead you to writing a function versus using a loop?

2. What is the error in the pseudocode below? Re-write the pseudocode in your answer document.

Declare Boolean finished = False

Declare Integer value, cube

While NOT finished

   Display "Enter a value to be cubed."

   Input value;

   Set cube = value^3

   Display value, " cubed is ", cube

End While

3. Write a Python program for problem #2. Your program should prompt the user for a value to be cubed, print the cube, and continue prompting until they are done. Take a screenshot of your code and output and paste into your answer document.

Answer 1

def Cube():
finished =False
while(not finished):
n = int(input("Enter value to be cubed:(-1 to stop):"))
if(n==-1):
finished=True
else:
cube = n**3
print(n," cubed is ",cube)
Cube()
  

output:

Enter value to be cubed:(-1 to stop):1
1 cubed is 1
Enter value to be cubed:(-1 to stop):2
2 cubed is 8
Enter value to be cubed:(-1 to stop):3
3 cubed is 27
Enter value to be cubed:(-1 to stop):-1
