How to access the data member of one function into another function inside same class in c++

Question

I wanted to declare the array of string to the limit provided by user. So I take limit in getData(), and declare the string inside getData function. As a whole I want to take students name and display it in the same class. Sorry for basic question and thank you in advance.

class student
{
    int limit;
public:
    void getData()
    {
        cout<<"Enter the number of students: ";
        cin>>limit;
        string name[limit];
        cout<<"Enter the names of students: \n";
        for(int i=0; i<limit; i++)
          cin>>name[i];
    }
   void showData()
    {
        cout<<"The list of students: \n";
        for(int i=0; i<limit; i++)
            cout<<name[i]<<endl;
    }
};
int main()
{
    student s1;
    s1.getData();
    s1.showData();
    return 0;
}

Here in this function, error comes as "name was not declared in this scope". sorry in advance if it is nonsense.

void showData()
        {
            cout<<"The list of students: \n";
            for(int i=0; i<limit; i++)
                cout<<name[i]<<endl;
        }

The error lies in

Cell celda = fila.createCell(ultimaCelda);

where you create a new cell in the row. You can't add a cell, while iterating over the list of all cells. Try creating a copy of the list you are wanting to edit and iterate over that one instead, so the other one becomes editable

the java.util.ConcurrentModificationException appears, when editing a list, that you are currently iterating over.
