Code :: BlocksでC ++プロジェクトをデバッグすると、「プログラムは信号SIGSEGV、セグメンテーション違反。In??（）（）を受信しました」

ここに最初の投稿。私は大学の課題をやっています。契約ブリッジのゲームのオープニングビッドをシミュレートするプログラムの実装を完了する必要があります。 main関数を含む次のファイルが提供されました。

/// File: bridge.cpp
/// Creates a deck of cards, shuffles them and displays them.

#include <iostream>
#include <iomanip>
#include <fstream>
#include "game.h"

const int NUM_DEALS = 4;

using namespace std;

int main(int argc, char *argv[]) {

   Game game;
   ifstream infile;
   bool fromFile = false;

   if (argc == 2) {

      // open the file and check it exists
      infile.open(argv[1]);
      if (infile.fail()) {
         cerr <<  "Error: Could not find file" << endl;
         return 1;
      }
      fromFile = true;
   }

   for (int deal = 0; deal < NUM_DEALS; deal++) {
      game.setup(fromFile);
      if (fromFile) {
         infile >> game;
      }
      game.deal();
      game.auction();
      cout << game << endl;
      cout << endl << "=============================================================="    << endl << endl;
      game.nextDealer();
   }

   // close the file
   if (argc == 2) {
      infile.close();
   }

   return 0;
}

カードオブジェクト、デッキオブジェクト、手オブジェクト、ゲームオブジェクトをシミュレートする他のクラスを完了しましたが、[ビルドと実行]をクリックするとプログラムがクラッシュしました。次の論理的な手順はデバッグでしたが、デバッグすると、デバッガウィンドウに次の出力が表示されました。

私はこの問題の解決策を求めてインターネットを探し回っていましたが、実行時にクラッシュし、デバッグ時にSIGSEGVがあるため、私のシナリオに適合するものは何もないようでした。ここで誰かが助けてくれることを願って、私は必死に笑っています。

ありがとう。

あなたのコードは確かに多すぎますが、問題はおそらくあなたのデッキコンストラクタに存在します。

Deck::Deck()
{
  // Here you allocate space for 52 pointers, not Cards
  deckArray = new Card*[52];
  ...
    // at this location there's no space for a card but for a pointer
    //*deckArray[counter] = Card((Rank)i, (Suit)j);
    // so you should do this instead:
    deckArray[counter] = new Card((Rank)i, (Suit)j);
    // to allocate needed space for the card
  ...
}

まとめると、カードの保管に必要なスペースを割り当てることはありません。

deckArrayのDeckはポインターの配列ですが、その要素を割り当てることはありません。

つまり、これらのポインターを介したすべての割り当ては、動作が定義されていない無効な逆参照です。

これらの要素をnewで割り当てるか、ポインタを使用しないようにする必要があります。これは通常、最良の方法です。

Hand** gameHands;をHand gameHands[4];に、Card** deckArray;をCard deckArray[52];に置き換えることをお勧めします。

（Javaとは異なり、「新規」がクラスをインスタンス化する唯一の方法であるのに対し、C++プログラマーは通常、必要な場合にのみそのWordを使用します。）

例として、gdbで実行コマンドを（並行して）ロード時に引数を指定していることを確認してください：
fix.c

  #include<stdio.h>
  #include<stdlib.h> 
  int main(int argc,char** argv)
  {
   int sum; 
   sum=(atoi(argv[1])+ atoi( argv[2]));
   printf("sum=%d",sum);
 }

オプション-gでコンパイルする

 gcc -g fix.c 
 gdb a.out

ここでgdbに入ります。コマンドライン引数が指定されていない場合は、gdbで引数を付けてコードを実行する必要があります。

enterを実行（引数がありません）

"Program received signal SIGSEGV, Segmentation fault."

だからここに引数を与えるようにしてください

 run 1 2

今は良いです！

SIGSEGVは通常、nullポインターまたは初期化されていないポインターを逆参照すると発生します。ブレークポイントの使用方法がわからない場合は、ロギングマクロを使用して問題の場所を特定することをお勧めします。例えば：

//#define NOLOGGING  // uncomment this line to disable logging

#include <iostream>
#ifndef NOLOGGING
#define LOG(msg)
#else
#define LOG(msg) std::cout << "[LOG] (" __FILE__ ":" << __LINE__ << ") from " << __func__ << "()\n    " << msg << "\n";
#endif
