C code for lm35 interfaced with PIC 16F690 microcontroller

hello

can anyone guide to me write the code in c for measuring of temperature i got a code and i need to change according to it


#include <pic.h>
/* cADC - Display the PICkit Pot Input Value on the built in LEDs

This program samples the voltage on RA0 using the ADC and Displays the
value on the 8 LEDs using "cLEDDisp 2" as a base.
