in Level.h

C++

class Level
{
public:

    Level(float g,int e,int l ,int s);
    void stage1();
    void stage2();
    void stage3();
private:
    void getInventory();
    void editInventory();
    void showInventory();
    void addInventory();
    void getID();
    float gold;
    int lvl,stage,exp;
    int ID[21];
    int IDP[21];
    int IDO[21];
    int IDPO[21];
    int k;
    char IDN[21][10];
    char IDNO[21][10];

    bool gameOver;

};

#endif // LEVEL_H

What is wrong with the code?

What I have tried:

Take a look at:
fluxi>> .... >>IDN[i];
IDN is two-dimensional array. So IDN[i] is in itself an array! And the same problem somewhat further down in your code with IDNO.

Solution 1

I guess that IDN is used by you as char array the operators of the fluxi object arent working.

C++

    for(int i=0; i<20; i++)
{
  fluxi >>IDN[i]; // calls char* operator
  fluxi >> i>ID[i]>>IDP[i];// calls int operator
}

Tip: Use longer variables names for better reading (of other people) and a full path your the files.
