C ++进程以状态3混乱终止 [英] C++ Process terminated with status 3 confusion
问题描述
我是编程的新手，但一直在下面的c ++教程，积累了一些PDF的最后一周左右帮助我。我没有找到任何在他们或在线，回答我的问题清楚够了。请原谅我的新手。

if（tiles [（x-1）+（y-1）* width]。 // Left-top瓦片状态，如果floor：WORKS
如果我理解正确，终止状态3指示我参考一个变量不正确地关于它是否是一个指针...？我最初遇到了这个问题，当我想访问从2Darray在Map.cpp中的一个单独的瓷砖tType字符串（虽然我可以访问布尔变量canWalk只是罚款...），并不能弄清楚什么是错的，所以我决定学习实现一个外部日志来找到问题...但我想我发现我的方式回到同样的问题，同时...

我提出这个问题的最初目的是（现在我意识到）从多文件程序中的任何* .cpp文件获取一个全局声明的对象。我刚找到这个答案： http://www.cplusplus.com/forum/beginner/3848/ 。
在您的Logfile.hpp中， 're missing #include< string> ：您的 LogFile 类变量之一声明为 std :: string ，所以你需要包括它。
在您的Engine.cpp中，您忘记在您的LogFile *日志中包括您的Engine.hpp;变量被声明。这将导致您的Engine.cpp文件中的错误，您尝试为其分配一个新的 LogFile 对象。
因此，将 #include< string> 添加到Logfile.hpp的顶部，并添加 #includeEngine.hpp到您的Engine.cpp
的顶部
I am very new to programming, but have been following c++ tutorials and amassing a number of PDFs for the last week or so to help me out. I couldn't find anything in them or online that answered my question clearly enough. Please forgive me for my newbie-ness.
Pertinent code:
Logfile.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
// ==============================

#include <iostream>
#include <fstream>

// Actual class
class Logfile { // Logfile

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

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

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

bool Logfile::isActive() { // Is log file active?

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";
}
}
Engine.hpp
// ==============================
// Forward declared dependencies
class Logfile;
class Engine { // Core system, main loop
public :
// Globally accessible variables
Logfile *log; // Declare 'log' as an empty pointer (*)
Engine.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)

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
If I understand correctly, a termination status 3 indicates that I am referencing a variable incorrectly in regards to whether it's a pointer or not...? I initially ran into the problem when I wanted to access the tType string from an individual tile in the 2Darray in Map.cpp (though I can access the boolean variable canWalk just fine...), and couldn't figure out what was wrong, so I decided to learn to implement an external log to find the problem...but I guess I found my way back to the same issue while doing that...
Any help is greatly appreciated, as is criticism, I have a lot to learn.

My initial purpose for asking this question was (now I realize) to get a globally declared object accessible from any *.cpp file in a multi-file program. I just found this answer: http://www.cplusplus.com/forum/beginner/3848/, in case this might be helpful to anyone else with a similar problem.
In your Logfile.hpp you're missing #include <string>: one of your LogFile classes variables are declared std::string so you need to include that.
In your Engine.cpp you forget to include your Engine.hpp where your LogFile *log; variable is declared. this results in an error in your Engine.cpp file where you try assigning a new LogFile object to it.
So add #include <string> to the top of your Logfile.hpp and add #include "Engine.hpp" to the top of your Engine.cpp
