I just writing the simple twenty one card game...now evth work and fine.
And I put cards from 2 to A with concerning value.But when the debug step coming '0'comes to input with value '10'(K is worth 10 etc). It make me so confused.
here is my code:

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

struct
{
   char face;
    unsigned int value;
} 
card[13] = 
{	{'2', 2},{'2', 3},{'2', 4},
    {'5', 5},{'6', 6},{'7', 7},
    {'8', 8},{'9', 9},{'10', 10},
    {'J', 10},{'Q', 10},{'K', 10},
    {'A', 1}
};

int main()
{

	cout<<"simple twenty one card"<<endl;
	cout<<"------------------------"<<endl;
	int compcard=3,compscore=0,urscore=0,draw=0,urcard=0;
	char cond;
	const int high=21;
	//int ur;
	do
	{
		int comptotal=0,urtotal=0;
		//srand(time(NULL));
		srand((unsigned)time(0));
		cout<<"how many cards u want?(up to 5 cards)"<<endl;
		cin>>urcard;
	if (urcard>5)
	cout<<"You could not get more than five cards!"<<endl;
	else
	{
		cout<<endl<<"Ur cards..."<<endl;
		for (int ucard=0;ucard<urcard;ucard++)
		{
			int x = rand() % 13;
			printf(" |%c| ", card[x].face);
			
			urtotal+=card[x].value;
			if(urtotal>42)
			{
				urtotal=urtotal-30;
			}
			else if(urtotal>31&&urtotal<42)
			{
				urtotal=urtotal-20;
			}
			else if(urtotal>21&&urtotal<32)
			{
				urtotal=urtotal-10;
			}
			
		}

		cout<<endl;
		cout<<"My cards..."<<endl;
		for (int Ccard=0;Ccard<compcard;Ccard++)
		{
			int x = rand() % 13;
			printf(" |%c| ", card[x].face);
			comptotal+=card[x].value;
			
			if(comptotal>42)
			{
				comptotal=comptotal-30;
			}
			else if(comptotal>31&&comptotal<42)
			{
				comptotal=comptotal-20;
			}
			else if(comptotal>21&&comptotal<32)
			{
				comptotal=comptotal-10;
			}
			
		}
		cout<<endl;
		cout<<"I have "<<comptotal<<" and you have "<<urtotal<<" so ";

		if(comptotal<=high&& urtotal<comptotal)
		{
			cout <<"I win "<<endl;
			compscore++;
		}
		else if(comptotal<=high&& urtotal>high)
		{
			cout <<"I win "<<endl;
			compscore++;
		}
		else if (urtotal<=high&& urtotal>comptotal)
		{cout<<" you win"<<endl;
		urscore++;
		}
		else if (urtotal<=high&& comptotal>high)
		{cout<<" you win"<<endl;
		urscore++;
		}
		else //(comptotal==urtotal)
		{cout<<"no win"<<endl;
		draw++;
		}
	}
		cout<<"wana play again(n/y?)"<<endl;
		cin>>cond;
	}while(cond=='y');
		cout<<"I win   : "<<compscore<<endl;
		cout<<"you win : "<<urscore<<endl;
		cout<<"we draw : "<<draw<<endl;
		cout<<endl;
		//cin>>ur;

		
}

example of output is like " |4||J||0||k||8|".
I dont want to include "0" . How can I do? Pls tell me.
Thanks in advance!:)

Hint
Ask yourself why is it displaying, then how you might ignore it?

I dont know .. I try already..:mad:

{'J', 10},{'Q', 10},{'K', 10},
    {'A', 1}

The above are all wrong. the values of J, Q, K and A are incorrect, should be 11, 12 , 13 and 14 respectively.

It's implementation defined what happens when you use an unrecognised character literal. You use '10', and that has too many expected characters, and C++ is seeing it as '0'.

#include <cstdio>

int main()
{
  using namespace std;

  char x = '10';

  printf( "%d\t%c\n", x, x );
}

Thanks a lot u guys...
you guys r so helpful..

but now i ran again after a bit change .. it still happen like that..
i change J to 11 and K to sth . not same value..
:sad:
