Please modify given code for pic16f877a

[Vinod kumar Warudkar]

I am Begener , so please help me given code is for PIC16f877a, its working as motion sensor, including 8 ir sensors,

& 14 indicator, I want to keep there only 8 indicator,

what i want that is whenever 1 sensor blocked then 1 indicator should be glow on , if 2 nd & four sensors are blocked then 2nd & 4th indicator should be glow on others sholud be off.

code is

#include<16F877A.h>
#include<string.h>
#use delay(clock4000000)

#byte portb  =  6
#byte leds1  =  7
#byte leds2  =  8

void main()
{
set_tris_b(0xff);            //set port b as input port
set_tris_c(0x00);            //set port c as output port
set_tris_d(0x00);            //set port d as output port
set_tris_e(0x00);            //set port e as output port
portb=0Xff;            //make all port b pins are high
leds1-0X00;            //switch off all leds
leds2=0X00;inputs(pin_c7)
output_high(pin_E0);        //set pin_E0 high
while(true)
{
while(input(pin_E0))
{

{
leds1=0x7f;    //switch on 7 leds

why to write such a lengthy code?

just get the input from sensor from 1 port

and give same output to indicators on another port

thats it……………..
