I could"nt understand the code can someone explain it to my step by step

Nrite the code as below to main.c. \#include > \#include "Icd.h" \#include // we need this library for C standard itoa function (integer to ascii function) _CONFIG(0x3ff9) unsigned int i,j=0 Microprocessors and lab. Application sheet Date: char buffer[6]; unsigned int x; void main(void) \{ Icd_init(); GIE=0; // we don't want interrupts while (1) \{ for (i=0;i htc.h //unsigned int conversiondatah, conversiondatal; // / Analog to Digital Converter initialization // void init_a2d(void) \{ // Right justified reading, Channel 0 Select, Fosc/2 select ADCONO=0;ADCON1=0x85; ADCONO=0; // select Fosc/2; ADCCON1 =0x5 olmal Microprocessors and lab.
