Stage 1: Design Documentation
Algorithm development describing the function of the program
The Christmas Parcel Delivery system is basically a Christmas parcel Delivery Calculator which
calculates the travel surcharge. The details of the parcel, the distance of the parcel to send and the
transportation cost per km is taken as an input from the user. Various operations and calculations are then
done on the input and the final delivery cost is displayed to the user.
An algorithm is defined as the set of steps describing the solution for a specific problem of the system.
Before starting with the coding part, I first designed the algorithm for the system to be designed keeping
in mind all the requirements of the system. The designed algorithm helped me a lot while the
development of the system. It helped me to be clear in the coding and helped in developing the code for
the system faster (Vogella, 2016).
Algorithm:
1) Display the welcome message for the Christmas Parcel Delivery System.
2) Loop: while (true) //to repeat the menu each time the user select and choice and choice gets
completed
3) Display the main menu having 4 choices.
4) Read the user input for the choice from the main menu.
5) If(user choice == 1) then
6) Reads the user input for cost per km for a package to be sent 100km or less.
7) Read the user input for cost per km for a package to be sent over 100km.
8) Display and store the user input.
9) End if
10) Else If(user choice == 2) then
11) Read the user input for receiver’s name.
12) Read user input for the weight of the parcel.
13) Read user choice for insurance(y/n)
14) Read user input for distance of the parcel to be send
15) Display and store the user input.
16) End else if
17) Else if (user choice == 3) then
18) If(distance of the parcel <= 100) then
19) Calculate transportation cost = (distance of the parcel to be sent)*(cost per km for 100km or less)
2

20) Else
21) Calculate transportation cost = (distance of the parcel to be send)*(cost per km for distance over
100km)
22) End if
23) If(Insurance choice == (‘Y’ | ‘y’)) then
24) Calculate Insurance cost = weight of parcel * 0.53
25) End if
26) Calculate total cost = transportation cost + Insurance cost
27) Display the calculated transportation cost, insurance cost and total cost to the user.
28) End else if
29) Else if(choice == 4) then
30) Display the thank you message
31) Exit from the system
32) End else if
33) End while
