C++ object member integer has ridiculous value (WTF) - c++

Question

This is for a poker game and I have class PokerTable defined in PokerTable.h
#include <iostream>
using namespace std;
class PokerTable
{
private:
int numPlayers;
int numPlaying;
int dealerPos;
int bigBlind;
int potSize;
int betSize;
bool flop;
bool turn;
bool river;
public:
//constructors
PokerTable();
PokerTable(int,int,int,int,int,bool,bool,bool);
//getters
int getNumPlayers(){return numPlayers;};
int getDealerPos(){return dealerPos;};
int getBigBlind(){return bigBlind;};
int getNumPlaying(){return numPlaying;};
int getPotSize(){return potSize;};
int getBetSize(){return betSize;};
bool getFlop(){return flop;};
bool getTurn(){return turn;};
bool getRiver(){return river;};
//void buttonShow(int);
//setters
void setBetSize(int inBetSize){betSize = inBetSize;};
void setBigBlind(int inBigBlind){bigBlind = inBigBlind;};
void setNumPlaying(int inNumPlaying){numPlaying = inNumPlaying;};
void setPotSize(int inPotSize){potSize = inPotSize;};
void setFlop(bool inFlop){flop = inFlop;};
void setTurn(bool inTurn){turn = inTurn;};
void setRiver(bool inRiver){river = inRiver;};
void setNumPlayers(int inPlayers){numPlayers = inPlayers;};
void setDealerPos(int inDealerPos){dealerPos = inDealerPos;};
};
PokerTable::PokerTable()
{
numPlayers = 9;
numPlaying = 9;
dealerPos = 1;
bigBlind = 20;
flop = false;
turn = false;
river = false;
}
PokerTable::PokerTable(int playerNum, int playingCount, int posDealer, int blindBig,int inPotSize, bool inFlop,bool inTurn,bool inRiver)
{
numPlayers = playerNum;
numPlaying = playingCount;
dealerPos = posDealer;
potSize = inPotSize;
bigBlind = blindBig;
flop = inFlop;
turn = inTurn;
river = inRiver;
}
In my watch list pokerTable.numPlayers has a random value up to 4 million before I even execute this next line of code.
PokerTable aPokerTable(9,9,1,20,30,false,false,false);
and afterwards here is pokerTable in my watch list:
- aPokerTable { numPlayers=2990892 numPlaying=9 dealerPos=9 ...} PokerTable
betSize 30 int
bigBlind 1 int
dealerPos 9 int
flop false bool
numPlayers 2990892 int
numPlaying 9 int
potSize 20 int
river false bool
turn false bool
Can anyone tell me why all the values are not what I declared them to be??!?!!
And how I can fix this?

Answer 1

aPokerTable { numPlayers=2990892 numPlaying=9 dealerPos=9 ...}
Note that dealerPos got assigned the value 9, that's wrong as well. If you look closely, you'll see that everything is shifted by 4 bytes.
Two possible reasons. The debugger could have picked the wrong address for aPokerTable, the actual address minus 4. That's unlikely. Or there's a mismatch between the definition of the PokerTable class as seen by pokertable.cpp and the other .cpp files that #include the pokertable.h include file. Where pokertable.cpp saw an extra member before the numPlayers member. Maybe you edited the header and deleted that member but ended up not recompiling pokertable.cpp for some mysterious reason. Build + Rebuild to fix. Do panic a bit if this actually works.

Answer 2

It's because in C++ before the constructor is called, variable uses the value that it already contains in its memory location that is a "random" value

Answer 3

I cannot reconstruct it because i dont have the full code. However, a random value near 4 million sounds like a pointer. When you store or retrieve a member variable maybe you did not de-reference the pointer. Please post the rest of the code so we can check if that's the case.

Answer 4

players[x] = *(new PokerPlayer(...));
That is a memory leak. What you probably want is:
players[x] = PokerPlayer(1000,(aPokerTable.getDealerPos())+1,false,0,1);
