Question

I started studying classes and now I faced a problem. I’m trying to put all my variables into a class, but I get errors:

main.cpp|6|error: expected identifier before string constant| 
main.cpp|6|error: expected ',' or '...' before string constant|
main.cpp|7|error: expected identifier before string constant|
main.cpp|7|error: expected ',' or '...' before string constant|

Although when I make them global everything works fine

    class Kauliukas{

        ifstream inFile("inFile.in");
        ofstream outFile("outFile.out");
        int n, akutes[100],k=0;

        void ivedimas();
        void skaiciavimas();
        void isvedimas();
};

What’s the problem?

Answer 1

Initialization goes in the constructor. That’s different than, for instance, C#.
You must define a constructor like

class Kauliukas {
public:
    Kauliukas() : inFile("inFile.in"), outFile("outFile.out"), k(0) {}
private:
    ifstream inFile;
    ofstream outFile;
    int n, akutes[100],k;

    void ivedimas();
    void skaiciavimas();
    void isvedimas();
};
