Question

I need to Create the flowchart and pseudocode for a program that accepts a user’s birth month and year and passes them to a method that calculates the user’s age in the current month and returns the value to the main program to be displayed. And apparently i need to also make a working version of this program in Python.

Answer 1

Pseudocode:

Function main()
   BEGIN
  
       Read User birth month and year
      
       ageInMonths <- calculateAge(month, year)
      
       Print years (ageInMonths / 12)
      
       Print months (ageInMonths % 12)
      
   END
  

Function calculateAge(month, year)
   BEGIN
  
       currentMonth <- Get Current Month
      
       currentYear <- Get Current Year
      
       ageYears <- (currentYear - year)
      
       If currentMonth < month Then
           ageMonths <- (12 - (month - currentMonth))
           ageYears <- ageYears - 1
       Else
           ageMonths <- (currentMonth - month)
          
       End If
  
       Return age in months ((ageYears*12) + ageMonths)
      
   END

Start calculateAge(month, year) Read birth month and year Find currentMonth and currentYear Calculate year difference ageYears currentYear -year agelnMonths calculateAge(month, year) Calculate age in-terms of years and months If currentMonth month rint Age in Years and months ageMonths 12 - (month currentMonth) Calculate ageMonths = currentMonth-month ageYears ageYears 1 Stop return agelnMonths

Python Program:

from datetime import datetime

def calculateAge(month, year):
   """ Calculates age in number of months """
  
   # Current month
   currentMonth = datetime.now().month
  
   # Current year
   currentYear = datetime.now().year
  
   # Age in years
   ageYears = currentYear - year;
  
   # Age in months
   if currentMonth < month:
       # Finding in months
       ageMonths = 12 - (month - currentMonth)
       # Finding in years
       ageYears = ageYears - 1;
   else:
       # Finding in months
       ageMonths = currentMonth - month

   # Returning age in months
   return ((ageYears*12) + ageMonths)
      
      
def main():
   """ Program that reads month and year and calculates age """
  
   # Reading birth month
   birthMonth = int(input("\n Enter birth month: "));
  
   # Reading year
   birthYear = int(input("\n Enter birth year: "));
  
   # Finding age
   ageInMonths = calculateAge(birthMonth, birthYear)
  
   # Age in years and months
   ageYears = int(ageInMonths / 12);
   ageMonths = ageInMonths % 12;
  
   # Printing age
   print("\n\n Age: " + str(ageYears) + " years, " + str(ageMonths) + " months. \n\n");
  
  
# Calling main function
main()
