Segmentation Fault when trying to push a string to the back of a list.
- by user308012
I am trying to write a logger class for my C++ calculator, but I'm experiencing a problem while trying to push a string into a list.
I have tried researching this issue and have found some information on this, but nothing that seems to help with my problem. I am using a rather basic C++ compiler, with little debugging utilities and I've not used C++ in quite some time (even then it was only a small amount).
My code:
#ifndef _LOGGER_H_
#define _LOGGER_H_
#include <iostream>
#include <list>
#include <string>
using std::cout;
using std::cin;
using std::endl;
using std::list;
using std::string;
class Logger
{
private:
list<string> *mEntries;
public:
Logger()
{
// Initialize the entries list
mEntries = new list<string>();
}
~Logger()
{
// Release the list
mEntries->clear();
delete mEntries;
}
// Public Methods
void WriteEntry(string entry)
{
// *** BELOW LINE IS MARKED WITH THE ERROR ***
mEntries->push_back(string(entryData));
}
void DisplayEntries()
{
cout << endl << "**********************" << endl
<< "* Logger Entries *" << endl
<< "**********************" << endl
<< endl;
for(list<string>::iterator it = mEntries->begin();
it != mEntries->end(); it++)
{
cout << *it << endl;
}
}
};
#endif
I am calling the WriteEntry method by simply passing in a string, like so:
mLogger->WriteEntry("Testing");
Any advice on this would be greatly appreciated.
