However, I have no idea how to define the variable as binary. Please help me.

Below are modified code but without the idea of defining binary variable for your reference.

IloArray <IloArray <IloArray <IloNumVar> > > y (env, n1);
        for (int i=0; i<n1; i++) {
            y[i] = IloArray <IloArray<IloNumVar> > (env, n2);
            for (int j=0; j<n2; ++j) {
                y[i][j] = IloArray <IloNumVar> (env, n3);
                for (int k=0; k<n3; ++k) {
                    y[i][j][k] = IloNumVar(env);
                    cout << i << " " << j << " " << k << " " << y[i][j][k] << endl;
                }
            }
        }
