digital clock calendar and temperature indicator(16F877A DS1307 LM35)

I would like to design a digital clock+calendar+temperature indicator as a part of my project at the college.
I intend to do it with PIC 16F877A and led or lcd displays.
Also the clock IC ds1307 and temperature sensor lm35/lm74.
I understand that ill need to use c programming for interfacing the ICs with PIC.
I need the help of all you experts out there.This is the first time i am using PIC.
Thank you

can u please give the code in c and guide me towards completing my project
