Hi guys,
I am working on a project on playing cards using enum and class. I really need help with the function defination in this project,
Here i will attach the question, your help will be highly appreciated. You can get bac to me trough jeymineb at yahoo.co.uk.
Thanks.
If you can help, I can give you what Ii have and we can work it out. Thanks again.
Use enum and class to define a Card class. The Card class has two private variables: color and number and all necessary methods including overloaded operator >.

This is how the game is played: Your program asks if the player wants a card, if yes, your program will randomly draw a card (you need to use the random number generator function twice, once for the color and once for the number of card) and displays the player's card on screen. then your program draws a card for dealer and displays the dealer's card as well as the comparison result, such as you win or dealer wins. Use a loop so that the player can play another game if he chooses.

Note on random number generator function.

C++'s library has a rand( ) function you can call to generate a random number between 0 and maximum integer the system allows. It should be seeded with an integer value that is sent to srand(), i.e, you first call srand(seed); before calling the rand( ) function. seed is an integer of your choice. rand( ) % n returns a random number in the range between 0 and n-1 inclusive.

So to generate a card, you can use the following

int seed=234; //use any number you want;

srand(seed);

color=rand( )%4+1; //rand( )%4 generates a random number between 0 and 3, plus 1, then it is a random number between 1 and 4.

similarly you can get a card number.

Hi,
Glad to know that. I was in a hurry and never got to read all rules at a go.
Here is what I already have. Trying to fix in parts
Thanks

Rank number;
public:
Card(){};
void printcard(Card X);
void SetSuit(Suit s ){ color = s; }
void SetRank(Rank r ){ number = r; }
void ShowCard();
bool operator > (Card X);
};

int main()
{

do {
Card firstCard;

You didnt post it int the

tags it makes it much easier to read

Some touch-ups:

#include <iostream>
#include <cstdlib> // for rand(), srand()
using namespace std;

const int declared_size=64;

enum Suit
{
};
enum Rank
{
two = 2, three, four, five, six, seven, eight, nine, ten,
jack, queen, king, ace
};

class Card
{
private:

Rank number;
public:
Card()
{
};
void printcard(Card X);
void SetSuit(Suit s )
{
color = s;
}
void SetRank(Rank r )
{

}
void ShowCard();

};

int main()

srand(seed);
do
{

cout<<"\n\n Do you want to draw a card"<<"\n Press Y for yes and n for no"<<endl;
cin>>start;
if ( start=='Y'||start=='y' )
{ //start of if

} //end of if

else
{
cout<<"\n Thank you for playing"<<"\n Goodbye!!!"<<endl;
} //end of else

} while ( start=='y'||start=='Y' );
return 0;
}

bool Card::operator > (Card X)
{
if ( number>X.number )return 1;
else if ( number<X.number )return 0;
if ( color>X.color ) return 1;
else return 0;
}

THanks alot.
But I still have a problem with calling the seed when drawing the cards since one has to draw the cards twice, and check for both its rank and seed. How can I do that within the main body function.
Hope to hear from you soon.
Thanks again.

I meant one has to compare both the rank and suit in each draw between the players and the seed has to be called twice since each player has to draw a card. Can I kindly have the syntax for this?
Thanks

I meant one has to compare both the rank and suit in each draw between the players and the seed has to be called twice since each player has to draw a card.

I don't think so. You seed the generator once, and once only per program execution (generally); you call the rand() function for each draw.

Hi,
here is how the seed is called twice: basically we have to draw two cards, one for the dealer and the other for the player hence have two calls. I will attach the program.

But I need some more clarification on how to use the static_cast in my main function : is there a way I can declare it globally so that I don't have to redefine every function? That is in the main body with switch (color) and switch(number). This is because on compiling the program, the static cast ommition erroris generated.
I really do appreciate your help.
Thanks

here is how the seed is called twice: basically we have to draw two cards, one for the dealer and the other for the player hence have two calls. I will attach the program.

That may make a rather dull game in which the same cards are always drawn.

#include <iostream>
#include <cstdlib>
using namespace std;

int main()
{
srand(4000);
cout << rand() << endl;
srand(4000);
cout << rand() << endl;
return 0;
}

/* my output
22441
22441
*/

This might be more interesting.

#include <iostream>
#include <cstdlib>
using namespace std;

int main()
{
srand(4000);
cout << rand() << endl;
cout << rand() << endl;
return 0;
}

/* my output
22441
22791
*/

Here is somethe to look at.

#include <iostream>
#include <iomanip>
#include <cstdio>
using namespace std;

int main()
{
static const char *rank[] =
{
"Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten",
"Jack", "Queen", "King", "Ace"
};
static const char *suit[] =
{
};

cout << "View a deck of cards:\n";
int card, r, s, i;
for ( card = 0; card < 52; ++card )
{
r = card % 13;
s = card / 13;
cout << setw(5) << rank[r] << " of " << suit[s] << endl;
}

cout << "Choose several cards at random:\n";
for (i = 0; i < 5; ++i)
{
card = rand() % 52;
r = card % 13;
s = card / 13;
cout << setw(5) << rank[r] << " of " << suit[s] << endl;
}
return 0;
}

/* my (partial) output
Choose several cards at random:
Queen of Clubs
King of Hearts
Ten of Clubs
Eight of Hearts
*/

[/edit]

But I need some more clarification on how to use the static_cast in my main function : is there a way I can declare it globally so that I don't have to redefine every function? That is in the main body with switch (color) and switch(number). This is because on compiling the program, the static cast ommition erroris generated.

Huh?

Uh! That is great. Thanks for the new way I can view it. But your output displays all cards but all the program needs is just to draw one card and make comparison with the other. Well, how does that come in?
I have used the above for the main fuction of the program but still it issues an error on direct reference to private variables on the switch statement.....well this seems weard .
Check this out: at x.color and x.number.
Kindly elucidate on this. Thanks again

void printcard(Card X)
{

switch(X.color)
{
case club:  cout<<"Club ";
break;
case diamond:   cout<<"diamond ";
break;
case heart: cout<<"heart ";
break;

The first part shows a full deck. The second part draws random cards; this was meant to be a hint.

I have used the above for the main fuction of the program but still it issues an error on direct reference to private variables on the switch statement.....well this seems weard .

How about putting the switch and its output into printcard? Then you can access the data that is intended to be private and produce just such an error when you try to access it directly.

Hi,
This doen't work either:

*** 10 errors in Compile ***

;) Granted, a lot of that is just lint, but there a number of syntax errors you ought to fix.

I think what I'm saying is that if printcard is supposed to be a member function, write it as a member function -- don't pass it any parameters -- and display the information of the object. From my earlier anticipation of what your response might be, but without much modification:

#include <iostream>
#include <cstdlib>
#include <ctime>

class card
{
int value;
public:
card() : value(std::rand() % 52) {}
void draw()
{
value = std::rand() % 52;
}
void show()
{
using std::cout;
using std::endl;
static const char *rank[] =
{
"2", "3", "4", "5", "6", "7", "8", "9", "10",
"Jack", "Queen", "King", "Ace"
};
static const char *suit[] =
{
};
cout << rank [ value % 13 ] << " of " << suit [ value / 13 ] << endl;
}
};

int main()
{
srand(time(0));
card player, dealer;
player.show();
dealer.show();
player.draw();
player.show();
return 0;
}

/* my output

Queen of Hearts

*/

Below is the complete program for playing the cards: It compiles but as usual picks same cards over again: Problem 1. I need to cout a seed to avoid this problem, where can I locate that. I have tried out( seen in the program) to use if-else statements but they don't work:

The seed cout part is in the main program after the first [do] statement

cin>>seed;
cout<<"\n";
}
else
{
cout<<" The number"<<seed<<" is out of range!!\n";

}

The == operator is at the end of the main fuction with the > operator.

1. If you need to re-seed a random number generator, it is likely an indicator of a design flaw, IMO.

A seed is meant to be planted and left to grow and do it's thing. It is not meant to be driven around like a car.

If you have a deck of cards, draw a card. It will likely be one of the cards.

If you stack the deck, and specify exactly where you cut the cards, it's not very fair.

2. I have no 2.

HI Guys, I have a question on Multidemensional arrays in matrices:

The question needs one to write a program that of a two 3by3 matrice that adds and also multiplies the two matrices together to display a reulting matrix
Below is my program:

/* Write a C++ program that reads two 3x3 matrices,
multiply these two matrices together and  displays
the resulting matrix.*/

#include <iostream>
using namespace std;

void Times(int A[][3], int B[][3],int C[][3]);//prototype int first, int last);

int main()
{
int N[3][3];
int M[3][3];
int K[3][3];
int i, j;

{

cout<<"Enter a three by three matrix for first array"<<endl;

for(i=0; i<3;i++)//for rows
{
for(j=0;j<3;j++)//for columns

cin>>N[i][j];//"\t";
}
cout<<" Martix for array N is:\n\n";

for(i=0; i<3;i++)
{
for(j=0;j<3;j++)

cout<<N[i][j]<<"\t";
cout<<endl;
}
}

//cout<<"Matrix N is:"<<"\n";

cout<<"Enter a three by three matrix for second array"<<endl;

for(i=0; i<3;i++)

{
for(j=0;j<3;j++)

cin>>M[i][j];
}

cout<<" Martix for array M is:\n\n";

for(i=0; i<3;i++)
{
for(j=0;j<3;j++)

cout<<M[i][j]<<"\t";
cout<<endl;

}
for(i=0;i<3;i++);
{
for(j=0;j<3;j++);
}
cout<<"The product is:"<<Times(K,3,3)<<endl;

//	cout<<endl;

return 0;
}

void Times(int A[][3], int B[][3],int C[][3])
{
int i,j, product;

for(i=0;i<3;i++);
{
for(j=0;j<3;j++);

product=(A[i][0]*B[0][j]+A[i][1]*B[1][j]+A[i][0]*B[0][j]);

C[i][j]=product;

cout<<C[i][j];
cout<<endl;

}

return ;

}

Kindly help me with a way to call the function for this multiplication.
Why is it that when you make the array range a global constant, the program does to work out i.r
const int SIZE=3, SIZE=3;
for both i and j?

I am seeing a problem in the following two lines:

void Times(int A[][3], int B[][3],int C[][3]);//prototype int first, int last);

cout<<"The product is:"<< Times(K,3,3) <<endl;

the protoype calls for the matricies and you are passing it a matrix and two constants...

but what other problems are you having with it?

My Major problem is how I can call the fuction with the two arrays: I couldn't figure out a syntax for it. Let me have an example of how to call this function.
Thank you

Let me have an example of how to call this function.
Thank you

Very simple way to pass them:

void myFunction(arg1 *[], arg2 *[], arg3 *[]);//prototype - doesn't have
//to be pointer array, but I prefer this notation

int myArray[3][3], myArray2[3][3], myArray[3][3];//create my variables

myFunction(myArray, myArray2, myArray3);//function call

Does that show you how to call the function using the three arrays?

void myFunction(arg1 *[], arg2 *[], arg3 *[]);//prototype - doesn't have

myFunction(myArray, myArray2, myArray3);//function call

Got it,
Thanks.
My next question is:
I want to overload the operations *+and_ using the class Mat and two class objects of mat to perform the above operations to a matrix of 3 by 3.
How do I pass the function to the defination part
i.e

class Mat
{
public:
Mat;
void setmat();
void display();
operator*(Mat M);
operator+(Mat A);
operator -(Mat S);
private:
int arrayz[3][3];
};
int main()
// Is this output right?
Mat M, N;

Mat K=M+N;
K.display()

K=M*N;
K.display

K=M-N
K.display

Mat Mat::operator +(Mat A)
{
//how do you pass this to main for all the overloaded operators?
}

I will high;y appreciate your help.
Thanks

Got it,
How do I pass the function to the defination part

I'm not sure what you mean by this...

int main()
// Is this output right?

I don't see any output... also, you don't have any curly brackets defining the main() function

Mat Mat::operator +(Mat A)
{
//how do you pass this to main for all the overloaded operators?
}

how do you pass this to main??? do you mean how do you call this function from main? You already did it using:

Mat K = M+N;

this is the same thing as:

Mat K.operator=((M.operator+(N)));

And where are you learning C++ from? School? Book?

And where are you learning C++ from? School? Book?

I use my head, well it has brains:) and heresay combined. Seems there is a gap in both, otherwise thanks:
I just realised I didnt formulate the question in a right way.

How do I access the private variable of an array in the function defination?
Thanks

How do I access the private variable of an array in the function defination?
Thanks

do you mean a private data member that is an array in your class?
since the function is a function of the class, it has access to it as if it were a global variable. Just use it's name:

Mat Mat::operator+(Mat d)
{
myVar += d.myVar;
//...
}
Mat Mat::operator+(Mat d)
{
myVar += d.myVar;
//...
}


Thanks . This is quite helpful. Just wondering though, how do you use the setmat to initialize the matrix objects?
Thanks again.
The setmat is a public function in the class of Mat.

Well, using what I've given you, it seems you need to combine two things... how to use private data members in a function.. and how to call the function... The rest is just writing the function to do so.
