  switch(stato){
	case 0:
	         while(!stato) {
				    
			printLifeBar();
			std::cout << "[1]" << move1 << std::endl;
		        std::cout << "[2]" << move2 << std::endl;
			std::cout << "[3]" << move3 << std::endl;
			std::cout << "[4]" << move4 << std::endl;
                        std::cin >> stato;
			system("clear");

			}
			break;

			case 1:
				move_msg.data = stato;
				stato = 0;

			break;

			case 2:
				move_msg.data = stato;
				stato = 0;
			break;

			case 3:
				move_msg.data = stato;
				stato = 0;
			break;

			case 4:
				move_msg.data = stato;
				stato = 0;
			break;

			default:
			stato = 0;
		}

All this code is put in a special loop(I'm program on raspberry pi with ros). The program is in loop while i don't kill it in a shell.
The program wait the input from user, but i need that the program continue to clear the screen and print another time because the life bar can change its value. Only when user press a number i need to read it. Have you got any idea? thanks :)

Sounds like system("cls") or similar might clear the screen and you need to investigate keyboard and timer interrupts to open or wake up the menu.

I use ubuntu so system("clear") work, the problem is: how can i do the interrupt from keyboard?
