C ++ questions.

1) Fill in the blanks.
a) STL algorithms work indirectly using ______ on container elements.
b) A ______ data member contains information belonging to the class.

2) Fix bugs and potential flaws in this code.

#include<iostream>

int main() {
vector<int> coordinates;

coordinates.push_back(34);
coordinates.push_back(768);
coordinates.push_back(516);
coordinates.push_back(834);

for(auto it = coordinates.begin(); it != coordinates.end(); it++)
if(*it == 768)
coordinates.erase(it);

for(auto& coordinate : coordinates)
cout << coordinate << ", ";
cout << '\n';
return 0;
}

3) Being able to point to a derived class object with a base class pointer is a result of the ISA relationship. True or False?
