I have a Note
and a Track
class which both *generator
member. When I create new Note
objects I want to link the generator
member of Note
to that of Track
but I can't figure out how to do this.
#include <iostream>
using namespace std;
class Generator {
public:
virtual float getSample(int sample)=0;
};
class Note {
public:
Generator *generator; // THIS IS WHAT IS CAUSING ME TROUBLE
Note(Generator *aGen){
generator = aGen;
}
};
class Synth : public Generator{
public:
virtual float getSample(int sample);
int varA;
int varB;
Synth(){
varA = 5;
varB = 8;
}
};
float Synth::getSample(int sample){
varA = sample;
varB = 3;
return 0;
}
class Track {
public:
Generator *generator;
Track(){
generator = new Synth();
}
};
int main() {
cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
Track track = Track();
cout << "test" << endl;
return 0;
}
I thought of doing something like this, but it's not working:
Track track = Track();
Note n = Note(&track.generator);
