Question

6. Write a program (compile and run), a pseudocode, and draw a flowchart for each of the following problems:

a) Obtain three numbers from the keyboard, compute their product and display the result.

b) Obtain two numbers from the keyboard, and determine and display which (if either) is

the smaller of the two numbers.

c) Obtain a series of positive numbers from the keyboard, and determine and display their average (with 4 decimal points). Assume that the user types the sentinel value -1 to indicate “end of data entry.”

Answer 1

# Answer a)   

# Pseudocode

#
# 1. Take three numbers from user A, B, C
# 2. D = A*B*C
# 3 Print(C)
#

# python Function that impliments above Pseudocode
def computProduct():
A=int(input("Enter A: "))
B=int(input("Enter B: "))
C=int(input("Enter C: "))
D=A*B*C;
print(D)

# Answer b)
# Pseudocode

# 1. Take Two numbers from user A,B
# 2. if A>B then,
# display(A is greater)
# else if B>A then,
# display(B is greater)
# else display(both are equal)
# end if
# python function that impliments above Pseudocode
def determineGreater():
A= int(input("Enter A: "))
B= int(input("Enter B: "))
  
if(A>B):
print("{} is greater than {}".format(A,B))
elif(B>A):
print("{} is greater than {}".format(B,A))
else:
print("Both are equal")

# Answer c)
# Pseudocode

# 1. counter =0, sum =0
# take input from user
# 2. loop while userInput is not -1
# sum = sum + userInput
# counter = counter +1
# take input from user
# 3. end loop
# 4. if counter is not 0
# average = sum/counter
# display(average rounded upto 4 decimal places)
# else
# display(0)

# Python program that impliments above Pseudocode
def computAverage():
counter =0
sum = 0
userinput =int(input("Enter a positive number: "))
while(userinput !=-1):
sum = sum+ userinput
counter = counter +1
userinput = int(input("Enter a positive number: "))
if counter !=0:
average = sum/counter
print(round(average,4))
else:
print(0)
  
# test our code
computProduct()
determineGreater()
