Related to Header file

#include<softwareserial.h>
#include<liquidcrystal.h>

These header file does not exist in Arduino software. Now what i do to send my data from software to Arduino UNO board. Or which library i use.

Check the case (capitalized letters.) For example, "liquidcrystal" != "LiquidCrystal"

or make use of the IDE's 'include library' function (under sketch) to avoid typo's
