Objectives: Program development with stubs
Task:
Write a program to compute the total value of a portfolio of shares and percentage
gain since purchase, as well as details of each share holding. A possible interaction of
this program is shown below. Because you don’t know how to obtain the price of a
particular share on a given date, you should use a stub function for this, which
provides the following interface:
double get_price (string companycode, int day, int month, int year)
/* returns the price in cents of a share in the company identified by */
/* companycode on the date (day, month, year) on the Irish Stock */
/* Exchange*/
Your stub for get_price() might initially return a fixed value in all instances. However
to allow more extensive testing of your program, get it to return a price based on
adding the day, month and year, (e.g. get_price (“BOI”, 3, 7, 2005) returns 2015) or
use a series of IF statements to return different prices for a few different company
codes, possibly affected by dates too.
Your program should also use functions to read details of each holding (perhaps from
a file instead of from the keyboard), to output details of each holding, to compute
values of holdings (this function should call on get_price()), and wherever else you
feel a function might be appropriate.
Notes – Strings:
Even if we haven’t covered strings yet, for this program you just need to be able to
declare a string variable and parameter, to read in and write out strings, and to test if a
string variable is equal to a string constant. All these things are as you would expect.
As long as you are only trying to read in a string that has no spaces in it
cin >> my_string;
works fine.
Sample interaction (but don’t feel totally constrained by this):
Enter a company code, and number of shares held: BOI 100
Enter the day month and year of purchase of these shares: 3 7 2005
100 BOI purchased for £2015.00, today worth £2022.00, gain of 3.47%
Do you have more shares? Y
Enter a company code, and number of shares held: FFA 350
Enter the day month and year of purchase of these shares: 22 11 1999
350 FFA purchased for £7112.00, today worth £7077.00, loss of 0.5%
Do you have more shares? N
Total purchase price was £9127.00.
Current value is £9099.00.
Loss since purchase of £28.00 or 0.3% of £9127.00

So what part of this is causing you the problem? I presume that you'd be able to write most of the program yourself and have only bits left that you don't understand how to implement...

Maybe this should be in Computers/Programming?
