Problem with 2D Array

Projects Programming
1

Hello,
i make a librarie to create menu and you can go in trought with simply two button.
I use a 2D array for name of every case.
But when i use the library, array blocked functioning, is there special writing for this ?

I put my code for you can see ! ^^

Menu.h

#ifndef Menu_h
#define Menu_h

#include "Arduino.h"

#define bulk 100

class Menu
{
	public:
		Menu(int pinLeft, int pinRight, int pinOk);
		void size(int row, int line);
		void title(int rowPos, int linePos, const char *title);
	
			
	private:
		int _row;
		int _line;
		int _rowPos;
		int _linePos;
		const char* _title;
		
		const char* allName [bulk][bulk];

};

#undef int
#undef char

#endif

Menu.cpp

/*

#include "Menu.h"

#include "Arduino.h"

/*Initialisation des paramètres de base */
Menu::Menu(int pinLeft, int pinRight, int pinOk)
{
	pinMode(pinLeft, INPUT);
	pinMode(pinRight, INPUT);
	pinMode(pinOk, INPUT);
	
}

void Menu::size(int row, int line)
{
	_row = row+1;
	_line = line+2;	
}

void Menu::title(int rowPos, int linePos, const char* title)
{
	_rowPos = rowPos;
	_linePos = linePos;
	_title = title;
	
	allName[_row][_line]=_title;
	
	allName[0][0]="Bienvenue";
	
}

Thanks

"array blocked functioning" in what way?

Also, (with "bulk" = 100) 100 x 100 x 2 [sizeof(char*)] = 20000 = ~20kb memory

That's not going to work....

In my program i have a Serial.print("Start"), when there are a 2D Array in library, the message does not appear, but when i delet the 2D array, it's ok. And if i put a 1D array it's ok too.

Thanks for your response
