Constructor error anytime I use private variables in VS Code - c++

Question

We're learning about constructors in class and I was trying to experiment with an overloaded constructor. When I run my program I keep getting an error written in the color red that says...
~
The ampersand (&) character is not allowed. The & operator is reserved for future use; wrap an ampersand in double quotation marks ("&") to pass it as part of a string.
^This only happens when I try to use private variables, when everything is public nothing goes wrong.
///Here's my code
#include <iostream>
using namespace std;
class JCole {
private:
string song;
string album;
int albumNum;
JCole::JCole(string _song, string _album, int _Num) {
song = _song;
album = _album;
albumNum = _Num;
}
};
int main() {
JCole album1("Punchin the clock", "The Off-Season", 6);
JCole album2("ATM","KOD",5);
cout << album1.song << " " << album1.album << " " << album1.albumNum << endl;
cout << album2.song << " " << album2.album << " " << album2.albumNum << endl;
return 0;
}

Answer 1

Your constructor is declared as private because you haven't changed the access setting.
Try this:
class JCole {
private:
string song;
string album;
int albumNum;
// Insert:
public:
JCole::JCole(string _song, string _album, int _Num) {
song = _song;
album = _album;
albumNum = _Num;
}
};
A private constructor is a nasty thing; only members of the class can call it. Thus wreaking havoc with external code that wants to instantiate this class.
Also, you can use many public:, private:, protected: within your class and in any order.
