C++ 进程因状态 3 混乱而终止

我对编程非常陌生，但在过去一周左右的时间里一直在关注 C++ 教程并积累了许多 PDF 来帮助我。我在其中或网上找不到任何足够清楚地回答我的问题的内容。请原谅我的新手。

日志文件.hpp

// =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
// HEADER :: CLASS INTERFACE FILE

// ==============================
// Include Guard
#ifndef __LOGFILE_INCLUDED__ // If Actor.hpp hasn't been included yet
#define __LOGFILE_INCLUDED__ // Define this for the compiler so it knows it has now been included

// ==============================
// Forward declared dependencies

// ==============================
// Included dependencies
#include <iostream>
#include <fstream>

// ==============================
// Actual class
class Logfile { // Logfile
public:
    // Globally accessible variables
    bool LACT; // Is log file active?
    std::ofstream LOG; // Actual log file
    std::string entry; // Data to be entered in log file

    // ==============================
    // Core methods
    Logfile(); // Constructor
    ~Logfile(); // Destructor

    // Additional methods
    bool isActive(); // Is log file active?
    void logEntry(std::string entry); // Make an entry in the log if 'LACT' is set to true
    void toggleLog(); // Toggle log file open or closed
};

extern Logfile *log; // This variable is declared in main

#endif // __LOGFILE_INCLUDED__

日志文件.cpp

// ==============================
// Included dependencies
#include "Logfile.hpp"

// ==============================
// Core methods
Logfile::Logfile() { // Constructor
    LACT = true; // Toggle logfile to active
    LOG.open ("LOG.txt"); // Open 'log.txt' and prepare it to receive 'LOG' entries
    LOG << "LOG FILE CLASS CONSTRUCTED\n";
    LOG << "LOG FILE OPENED\n";
}

Logfile::~Logfile() { // Deconstructor
    LOG << "LOG FILE CLOSED\n";
    LOG << "LOG FILE CLASS DECONSTRUCTED";
    LOG.close(); // Close log file
}

// Additional methods
bool Logfile::isActive() { // Is log file active?
    if ( LACT ) return true;
    else return false;
}

void Logfile::logEntry(std::string entry) { // Make an entry in the log if 'LACT' is set to true
    if ( LACT ) LOG << entry << std::endl;
}

void Logfile::toggleLog() { // Toggle log file open or closed
    if ( LACT ) { // Log file is active
        LOG << "LOG FILE CLOSED\n";
        LOG.close(); // Close log file
    } else { // Log file is inactive
        LOG.open ("LOG.txt"); // Open 'log.txt' and prepare it to receive 'LOG' entries
        LOG << "LOG FILE OPENED\n";
    }
}

引擎.hpp

// ==============================
// Forward declared dependencies
class Logfile;

class Engine { // Core system, main loop
public :
    // Globally accessible variables 
    Logfile *log; // Declare 'log' as an empty pointer (*)

引擎.cpp

// ==============================
// Included dependencies
#include "Logfile.hpp"

// ==============================
// Core methods
Engine::Engine() { // Constructor method
    // Initialization
    log = new Logfile(); // Declare 'log' as pointer to access log file
    TCODConsole::initRoot(80,50,"Testbed",false); // Create 'root' console (not fullscreen)
    if ( log->isActive() ) log->logEntry("(TCODConsole) Root console initialized"); // WORKS

Map.hpp

// ==============================
// Forward declared dependencies
class Logfile;

extern Logfile *log; // Pointer exists in Engine.hpp

Map.cpp

// ==============================
// Included dependencies
#include "Logfile.hpp"

if ( log->isActive() ) log->logEntry("(TCODConsole) Root console initialized"); TERMINATION STATUS 3
if ( tiles[(x-1)+y*width].tType =="floor" ) tally++; // Left tile status, add 1 to tally if floor  :  TERMINATION STATUS 3
if ( tiles[(x-1)+(y-1)*width].canWalk ) tally++; // Left-top tile status, add 1 to tally if floor  :  WORKS

如果我理解正确的话，终止状态 3 表明我错误地引用了一个变量，无论它是否是指针......？当我想从 Map.cpp 中的 2Darray 中的单个图块访问 tType 字符串时，我最初遇到了问题（尽管我可以很好地访问布尔变量 canWalk...），并且无法弄清楚出了什么问题，所以我决定学习实现外部日志来查找问题...但我想我在这样做时找到了回到同一问题的方法...

非常感谢任何帮助，批评也是如此，我有很多东西要学习。

我问这个问题的最初目的是（现在我意识到）获得一个可以从多文件程序中的任何 *.cpp 文件访问的全局声明的对象。我刚刚找到这个答案：http://www.cplusplus.com/forum/beginner/3848/ http://www.cplusplus.com/forum/beginner/3848/，以防这可能对遇到类似问题的其他人有帮助。

在您的 Logfile.hpp 中您丢失了#include <string>: 你的一个LogFile类变量被声明std::string所以你需要包括它。

在您的 Engine.cpp 中，您忘记将您的 Engine.hpp 包含在您的 LogFile *log; 中变量被声明。这会导致您尝试分配新的 Engine.cpp 文件中出现错误LogFile反对它。

So add #include <string>到 Logfile.hpp 的顶部并添加#include "Engine.hpp"到 Engine.cpp 的顶部
