Vector of pointers to base class, odd behaviour calling virtual functions
- by Ink-Jet
I have the following code
#include <iostream>
#include <vector>
class Entity {
public:
virtual void func() = 0;
};
class Monster : public Entity {
public:
void func();
};
void Monster::func() {
std::cout << "I AM A MONSTER" << std::endl;
}
class Buddha : public Entity {
public:
void func();
};
void Buddha::func() {
std::cout << "OHMM" << std::endl;
}
int main() {
const int num = 5; // How many of each to make
std::vector<Entity*> t;
for(int i = 0; i < num; i++) {
Monster m;
Entity * e;
e = &m;
t.push_back(e);
}
for(int i = 0; i < num; i++) {
Buddha b;
Entity * e;
e = &b;
t.push_back(e);
}
for(int i = 0; i < t.size(); i++) {
t[i]->func();
}
return 0;
}
However, when I run it, instead of each class printing out its own message, they all print the "Buddha" message. I want each object to print its own message: Monsters print the monster message, Buddhas print the Buddha message.
What have I done wrong?
