Tutorial #6 - Your first proper game. Lost Fortune. Part 3

[center]Welcome to Tutorial No. 6 (part 3)
In this tutorial you will putting everything you have learned
so-far into a game.[b][/center]
[font=trebuchet ms][b]Telling the story -[/font]
So far your script will look like -
[code]
#include <iostream>
#include <string>
using namespace std;
int main()
{
const int GOLD_PIECES = 900;
int adventurers, killed, survivors;
string leader;
// Introducing the game
cout << "\tWelcome to Lost Fortune." << endl;
cout << "\tPlease enter some of your information for the
story.\v"
// Getting the users information
cout << "Please enter a random number" << endl;
cin >> adventurers;
cout << "Please enter a smaller number" << endl;
cin >> killed;
cout << "Please enter you'r last name" << endl;
cin >> leader;
survivors = adventurers - killed;
}
[/code]
Now all you need to make the game complete is the story itself.
I took this story from a book I bought "Beginning C++ through
game programming second edition" by Michael Dawson
This is the story -
(I used random numbers and a random name to make the story not
look weird.
I also added a small note at the end of each line where there
are variables involved or math functions.)
[code]A brave group of 20 set out on a quest (variable
used: adventurers = 20)
In search of the lost treasure of the ancient dwarves.
The group was led by the legendary rogue, McDonald.
(variable used: leader = McDonald)
Along the way, a band of marauding ogers ambushed the party.
All fought bravely under the command of McDonald,
(variable used: leader = McDonald)
and the ogers were defeated, but at a cost.
of the adventurers, 9 were vanquished, (variable used:
killed = 9)
leaving just 11 in the group. (variable used: survivors
= 11)
The party was about to give up all hope,
But while laying the deceased to rest,
they stumbled upon the buried fortune.
So the adventurers split 900 gold pieces. (variable
used: GOLD_PIECES = 900)
McDonald held on to the extra 9 pieces
(calculation for extra pieces: GOLD_PIECES % survivors)
to keep things fair of course.
[/code]
This is the code for the story.
[code]
cout << "\nA brave group of " << adventurers << " set out on a
quest ";
cout << "-- in search of the lost treasure of the Ancient
Dwarves. ";
cout << "The group was led by that legendary rogue, " << leader
<< ".\n";
cout << "\nAlong the way, a band of marauding ogres ambushed
the party. ";
cout << "All fought bravely under the command of " << leader;
cout << ", and the ogres were defeated, but at a cost. ";
cout << "Of the adventurers, " << killed << " were vanquished,
";
cout << "leaving just " << survivors << " in the group.\n";
cout << "\nThe party was about to give up all hope. ";
cout << "But while laying the deceased to rest, ";
cout << "they stumbled upon the buried fortune. ";
cout << "So the adventurers split " << GOLD_PIECES << " gold
pieces.";
cout << leader << " held on to the extra " << (GOLD_PIECES %
survivors);
cout << " pieces to keep things fair of course.\n";
[/code]
The code and narrative are pretty clear. I will point out one
thing though, to calculate the number of gold pieces that the
leader keeps, we have to use the modulus operator in the
expression {GOLD_PIECES % survivors}. The expression evaluates
the remainder of
{GOLD_PIECES % survivors}, which is the number of gold pieces
that would be left after evenly dividing the stash among all of
the surviving adventurers.
So now your full script should look like
[code]
#include <iostream>
#include <string>
using namespace std;
int main()
{
const int GOLD_PIECES = 900;
int adventurers, killed, survivors;
string leader;
// Introducing the game
cout << "\tWelcome to Lost Fortune." << endl;
cout << "\tPlease enter some of your information for the
story.\v"
// Getting the users information
cout << "Please enter a random number" << endl;
cin >> adventurers;
cout << "Please enter a smaller number" << endl;
cin >> killed;
cout << "Please enter you'r last name" << endl;
cin >> leader;
survivors = adventurers - killed;
cout << "\nA brave group of " << adventurers << " set out on a
quest ";
cout << "-- in search of the lost treasure of the Ancient
Dwarves. ";
cout << "The group was led by that legendary rogue, " << leader
<< ".\n";
cout << "\nAlong the way, a band of marauding ogres ambushed
the party. ";
cout << "All fought bravely under the command of " << leader;
cout << ", and the ogres were defeated, but at a cost. ";
cout << "Of the adventurers, " << killed << " were vanquished,
";
cout << "leaving just " << survivors << " in the group.\n";
cout << "\nThe party was about to give up all hope. ";
cout << "But while laying the deceased to rest, ";
cout << "they stumbled upon the buried fortune. ";
cout << "So the adventurers split " << GOLD_PIECES << " gold
pieces.";
cout << leader << " held on to the extra " << (GOLD_PIECES %
survivors);
cout << " pieces to keep things fair of course.\n";
system ("pause");
return 0;
}
[/code]
And that is your first game in C++!
