Thread: Trying to make a string identifier

Ok i compiled your code and got rid of the errors, take a look

Code:

#include <iostream>
#include <string>
#include <time.h>
#include <cstdlib>
#include <stdlib.h>
using namespace std;

//==================================================  ===========

int PlayerCardA=0;//PLAYER CARD 1
int PlayerCardB=0;//PLAYER CARD 2
int PlayerTotal=0;//PLAYER TOTAL
int ComputerCardA=0;//COMPUTER CARD 1
int ComputerCardB=0;//COMPUTER CARD 2
int ComputerTotal=0;//COMPUTER TOTAL
int Bank=1000;//BANK
int xWager=0;//WAGER
int xNewCard=0;//NEW CARD
bool xSync=true; //SYNC TRUE?
bool xHit_Stay=false; //HIT OR STAY?

//==================================================  ===========

void PlayerCards(int& A, int& B);//PLAYER CARDS
void ComputerCards(int& A, int& B);//COMPUTER CARDS
int Wager(int& A);//WAGER
int NewCard();//NEW CARD
void Winner(bool& A, bool& B, bool& C);//WINNER
int Display(int A, int B, int C, int D);//DISPLAY CARDS
bool Hit_Stay();//HIT OR STAY


//==================================================  ===========

int main(void)
{

	srand(time(NULL));  

	cout<<"Welcome to Black Jack. You have $1000 in the bank.\n\n";
	cout<<"------------------------------------------------------";
	cout<<"\nPress enter to continue...";
	cin.get();
	system("cls");
	do
	{
		xWager = Wager(xWager); //CALL WAGER FUNCTION
		PlayerCards(PlayerCardA,PlayerCardB);//GENERATE PLAYER CARDS
		ComputerCards(ComputerCardA,ComputerCardB);//GENERATE COMPUTER CARDS
		Display(PlayerCardA, PlayerCardB, ComputerCardA, ComputerCardB);//DISPLAY TOTALS
	}
	while(xSync == true);

	return(0);
}

//==================================================  ===========

int Wager(int& A)
{

	cout<<"Please enter your wager:$"; //REQUEST WAGER
	cin>>xWager; //GET WAGER
	system("cls");

	return(A);

}

//==================================================  ===========

void PlayerCards(int& A, int& B)
{

	A = 2 + (rand() % (14 - 2 + 1));
	B = 2 + (rand() % (14 - 2 + 1));		

}

//==================================================  ===========

void ComputerCards(int& A, int& B)
{

	A = 2 + (rand() % (14 - 2 + 1));
	B = 2 + (rand() % (14 - 2 + 1));		

}

//==================================================  ===========

int Display(int A, int B, int C, int D)
{

	string CardA = "boo";
	string CardB = "bee";
	string CardC = "baa";
	string CardD = "bum";

	//=====================

	int E = A+B; // PLAYER TOTAL = PLAYERTOTALA+PLAYERTOTALB
	int F = C+D; // COMPUTER TOTAL = COMPUTERCARDA+COMPUTERCARDB
	
	cout<<"You drew a "<< CardA << " and a "<< CardB <<"  for a total of " << E <<".\n";
	cout<<"The computer drew a "<< CardC << " and a "<< CardD <<" for a total of "<< F <<".\n";

	cout<<"\nPress enter to continue...";
	cin.get();

	system("cls");
	return 0;
}

all i did was fix your include of iostream.h to iostream, and i changed the prototype and the function.

is there a way i can convert ints into strings?

As I was saying....

Code:

string mystring = "99999";
char * mychararray;

mychararray =  mystring.data();

long mystring2numbers = atoi( mychararray );

this should work if you can follow, there may be an easier way,
i dont know for sure, havent done much work with this.

if you are having a hard time following this, search on google
for atoi and string.data

what about the other way around?

like

int x = 4
string y;

make y = x

Code:

int mynumber = 4;
char mychar = itoa(mynumber);
string mystring = mychar;

i believe thats correct

Bah beaten.

ILoveVectors, your methods of converting are bad. The data() function doesn't necessarily return a null-terminated character array, and therefore will cause your code to not work as expected, and possibly crash. Use c_str() instead if you want to get to a character array. Or use a stringstream. Also, your second method uses the non-standard itoa function which usually returns a character array, not a single character. Even if it returned a single character, that's not very helpful for two digit numbers. Use a stringstream.

See this FAQ (39.1 & 39.2) for stringstream examples, or for a simpler examples I believe there is a FAQ on this website.
