Invalid digit 8 in octal constant arduino как исправить - Исправление недочетов и поиск решений вместе с Examum.ru

Скетч для робота с ик приемником, ide ругается:invalid digit «8» in octal constant
Понять в чем проблема смог, а как решить ее не могу понять все еще.
Скетч:

const long IR_COMMAND_FORWARD_CODES[] = { 377281, 7503, 2 };
const long IR_COMMAND_BACKWARD_CODES[] = { 377282, 1583, 8 };
const long IR_COMMAND_TURN_LEFT_CODES[] = { 377278, 0783, 4 };
const long IR_COMMAND_TURN_RIGHT_CODES[] = { 377279, 7103, 6 };
const long IR_COMMAND_FORWARD_LEFT_CODES[] = { 377278, 4863, 1 };
const long IR_COMMAND_FORWARD_RIGHT_CODES[] = { 377280, 1183, 3 };
const long IR_COMMAND_BACKWARD_LEFT_CODES[] = { 377280, 5263, 9 };
const long IR_COMMAND_BACKWARD_RIGHT_CODES[] = { 377278, 8943, 7 };
const long IR_COMMAND_STOP_CODES[] = { 377281, 3423, 5 };
const long IR_COMMAND_VERY_SLOW_CODES[] = { 377280, 3223, 40 };
const long IR_COMMAND_SLOW_CODES[] = {377281, 9543, 43 };
const long IR_COMMAND_FAST_CODES[] = { 377278, 6903, 26 };
const long IR_COMMAND_VERY_FAST_CODES[] = { 377279, 0473, 27 };
А что вам непонятно? 0 перед числом говорит, что это число — в восьмеричной системе счисления, а там, как известно, нет цифры 8.

0x перед числом — говорит, что это число в шестнадцатеричной системе счисления.

Короче — уберите 0 спереди у чисел 0783 и 0473 — они там не нужны.

Hi.

I came across a strange errormessage and it might be a bug in the 1.0.5 version of the arduino software.

The part of the code that gets the error looks like this:
» if (i == 01) catchd01 = t;
if (i == 02) catchd02 = t;
if (i == 03) catchd03 = t;
if (i == 04) catchd04 = t;
if (i == 05) catchd05 = t;
if (i == 06) catchd06 = t;
if (i == 07) catchd07 = t;
if (i == 08) catchd08 = t;
if (i == 09) catchd09 = t;
«

And the compiler only complains on the last 2 lines.

error: invalid digit «8» in octal constant
error: invalid digit «9» in octal constant

So, whats wrong? it compiles good if all zeros are removed from the i == part.
But shouldnt it complain on all 9 lines if its the zero that is the problem.. why just 8 and 9?

because the compiler thinks you are using OCTAL number, and octal number
goes from 0 to 7.
Also, if this was a bug, was a COMPILER fault, you should had ask to
avr-gcc’s folks.

A constant number starting with «0» is interpreted as octal by the compiler, you must write «8» instead of «08».
BTW programming questions should be addressed to the forum.

i m learning c programming and i don’t knonw what is going wrong with this program

the error code in the build message is

error: invalid digit «8» in octal constant.

can any one help please , and thank you =)

#include <stdio.h>
#include <stdlib.h>

int ch ;
int codeS , codeH;
int ph = 1 , ad = 2 , lb = 3 , us = 4;

  printf("n Bienvenue à SHCPahrma n Veulleiz Choisir Votre Code Section n ph : 1t ad : 2t lb : 3t us : 4tn num secteur ");
  scanf("%d",&ch);
  printf("n Entrer votre code secteur t = ");
  scanf("%d",&codeS);
  printf("n Entrer Code Horaire t = ");
  scanf("%d",&codeH);




  // ch = 1223 ;
   //printf("%d",ch);
  if ((ch == 1) && (codeS == 1111) && (codeH == 0815))
