C++ remove_if overwriting my vector
Pregunta
My remove_if seems to be overwriting the elements that are not filtered out with values of filtered out elements. The purpose of these code is to allow user to filter and display only teacher from a certain category. (Not deleting any element) Here are some of the code
static string compare;
static string debug;
bool filter_Cat (Teacher &t)
{
return (t.getCat() != compare);
}
void filterCat (vector<Teacher> &t)
{
vector<Teacher>::iterator i;
vector<Teacher>::iterator newedited = remove_if(t.begin(), t.end(), filter_Cat);
for (i = t.begin(); i != newedited; ++i)
{
Teacher& te = *i;
te.getName();
cout << "\t";
te.getCategory();
cout << "\t";
te.getLocation();
}
}
void filterTutorCat(vector<Teacher> &t)
{
int choice;
cout << "No\tCategory" << endl
<< "1\tEnglish" << endl
<< "2\tMath" << endl
<< "3\tScience" << endl
<< "Choose the category you wish to filter :";
cin >> choice;
getline(cin, debug);
if(choice <= 3 && choice > 0)
{
if (choice == 1)
{
compare = "English";
filterCat(t);
}
if (choice == 2)
{
compare = "Math";
filterCat(t);
}
if (choice == 3)
{
compare = "Science";
filterCat(t);
}
}
else
{
cout << "Invalid Option" << endl;
}
}
