Try this code I created,when I use it in Borland C++ and try the remove-function a debug session opens up and it points to a file called "xstring",and it is saying "EAccessViolation".
it points to this line in the file:
return (compare(0, _Mysize, _Right._Myptr(), _Right.size()));
//---------------------------------------------------------------------------

string ammount;
};

cin.ignore(1000, '\n');
switch (answ) {
case '1':
new_mail(mail);
break;
case '2':
show_mail(mail);
break;
case '3':
remove(mail);
break;
case '4':
exit(1);
default:
cout<<"Choice not recognized";
}
}
while(contin);
return 0;
}

getline(cin, p.name);

getline(cin, p.ammount);
l.push_back(p);
}
//------------------------------Show_Mail-------------------------------------
void show_mail(list<Mail> l){
list<Mail>::iterator it;
cout<<"\nAll mail:\n\n";
for (it = l.begin(); it != l.end(); it++) {
cout<<(*it).name<<'\t'<<'\t'<<(*it).ammount<<endl;
}
}
//------------------------------Remove----------------------------------------

getline(cin, name);
for (it = l.begin(); it != l.end(); it++) {
if ((*it).name == name) {

}
}
}

Why does it show this error,and how can I solve it?
