Here is my sketch:

#include<ESP8266WiFi.h>

char* ssid = "xxxxxxxx";
char* pass = "xxxxxxx";

void setup() {
 WiFi.begin(ssid,pass);
 Serial.begin(9600);
 while(WiFi.status()!=WL_CONNECTED)
 {
  Serial.print(".");
  delay(500);
  }
  Serial.println("");
  Serial.print("IP Address: ");
  Serial.print(WiFi.localIP());
}

Here is the error:
