Simple arduino 2-sensors (DS18B20) termometer + I2C LCD sketch

//OneWire bus suport

//DS18B20 temperature sensor support
#include <DallasTemperature.h>
//DS18B20 sensor pin
#define ONE_WIRE_BUS 8

// Setup a oneWire instance to communicate with any OneWire devices 
// (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);
 
// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);

LiquidCrystal_I2C lcd(0x27,16,2);  // set the LCD address to 0x27 for a 16 chars and 2 line display

void setup()
{
  lcd.init();
  lcd.backlight(); //Turns backlight on
  sensors.begin();
}

void loop()
{  
  sensors.requestTemperatures();
  
  //Read first sensor
  float temp = sensors.getTempCByIndex(0);
  
  //Print first sensor results
  lcd.setCursor (0, 0 );
  lcd.print("T1: ");
  lcd.print(temp);
  lcd.print("      ");

  //Read second sensor  
  temp = sensors.getTempCByIndex(1);
  
  //Print second sensor result
  lcd.setCursor (0, 1 );
  lcd.print("T2: ");  
  lcd.print(temp);
  lcd.print("      ");
  
  //Wait 0.1 sec
  delay(100);  
}

As the sensors are connected to the Arduino, I shows the temperature of only one

hello ,im new to this whole ardunio system, but after I copied and pasted your code.i tried to compile it,
it came back with the error : c:\users\hp notebook\documents\ardunio\libraries\liquidcrystal_i2c.cpp:3:23: fatal error: wprogram.h: no such file or directory
#include "wprogram.h" compilation terminated.
exit status 1
error compiling for board ardunio/genuine uno.
if anyone has any idea on what I can do please respond thanks in advance to everyone.

Excellent Alexander, thanks so much, just what I was looking for, and from a fellow Washingtonian!!!
