Ошибка stray 342 in program - Не ошибается лишь тот, кто ничего не делает!

I’m getting these errors in my program after pasting in some code:

showdata.cpp:66: error: stray ‘342’ in program
showdata.cpp:66: error: stray ‘200’ in program
showdata.cpp:66: error: stray ‘235’ in program
showdata.cpp:66: error: stray ‘’ in program
showdata.cpp:66: error: stray ‘342’ in program
showdata.cpp:66: error: stray ‘200’ in program
showdata.cpp:66: error: stray ‘235’ in program
showdata.cpp:67: error: stray ‘342’ in program
showdata.cpp:67: error: stray ‘200’ in program
showdata.cpp:67: error: stray ‘235’ in program
showdata.cpp:67: error: stray ‘’ in program
showdata.cpp:67: error: stray ‘342’ in program
showdata.cpp:67: error: stray ‘200’ in program
showdata.cpp:67: error: stray ‘235’ in program

Here are the two lines that are causing the errors.

size_t startpos = str.find_first_not_of(” t”);
size_t endpos = str.find_last_not_of(” t”);

How can I fix this?

The symbol ” is not ". Those are called ‘smart quotes’ and are usually found in rich documents or blogs.

The lines

 size_t startpos = str.find_first_not_of(” t”); 
 size_t endpos = str.find_last_not_of(” t”);

have some «special» kind of double quotes, try the following:

 size_t startpos = str.find_first_not_of(" t"); 
 size_t endpos = str.find_last_not_of(" t");

This sort of error message, error: stray ‘xyz’ in program, can appear with any other character or symbol that is not recognized by the compiler as a legal one.

Sharing my personal experience:

 - bool less<const char∗>(const char∗ a, const char∗ b)
 - bool less<const char*>(const char* a, const char* b)

The former one is copy-pasted from a PDF file. It doesn’t compile.

The latter one compiles as expected.

You can use the sed command to fix these issues.

This will give you a quick preview of what will be replaced.

sed s/[”“]/'"'/g File.txt

This will do the replacements and put the replacement in a new file called WithoutSmartQuotes.txt.

sed s/[”“]/'"'/g File.txt > WithoutSmartQuotes.txt

This will overwrite the original file.

sed -i ".bk" s/[”“]/'"'/g File.txt

Всем привет . Проблема с инициализацией дисплея nokia 5110. Взял скетч с инета для проверки . А компилятор выдал ошибку 342. Что это за ошибка я не смог найти . Прошу помочь. Вот скетч.

#include <LCD5110_Graph.h>

#include <LCD5110_Basic.h>
LCD5110 LCD(7, 6, 5, 4, 3); //обьявляем дисплей с указанием пинов подключения

extern uint8_t SmallFont[]; //указываем наличие массива со шрифтом SmallFont в библиотеке

extern uint8_t MediumNumbers []; //указываем наличие массива со шрифтом MediumNumbers в библиотеке



void setup() {
 LCD.InitLCD(); //инициализируем дисплей
 

}

void loop() {
 LCD.disableSleep(); //выводим дисплей из режима сна

LCD.clrScr(); //очищаем дисплей

LCD.setFont(SmallFont); //устанавливаем шрифт SmallFont

LCD.print(“Hello World!”, CENTER, 2); //выводим “Hello World!” на второй строчке с равнением по центру



LCD.setFont(MediumNumbers); // устанавливаем шрифт MediumNumbers

for (int i=0; i<=5; i++) {

     LCD.clrScr(); //очищаем экран

     LCD.print(i, CENTER, 20); //выводим значение i по центру 20 строчки

     delay(1000);

}



LCD.enableSleep(); //вводим дисплей в режим сна на время длительной паузы

delay(5000);

When I try to compile my code it says «stray ‘342’ in program

My code:

If I copy your provided code in a vim-editor you can see some strange characters. <202c>

switch (val, HEX) {
  4 
  5     case 0x807FB24D<202c>:
  6       Serial.println("Stisknuto PLAY");
  7       tone(2, fre);
  8       break;
  9     case <202d>0x807FB04F<202c>:

I’ve removed them for you:

#include <IRremote2.h>
#include <IRremoteInt.h>

#define pinIN 11

uint32_t val;
uint32_t prev;
int fre = 0;

IRrecv remote(pinIN);
decode_results result;

void setup() 
{
  Serial.begin(9600);
  remote.enableIRIn();
  pinMode(2, OUTPUT);
}

void loop() 
{
  if (remote.decode(&result)) 
  {
    val = result.value;
    if (val == 0xFFFFFFFF) 
    {
      val = prev;
    }
    prev = val;
    detekceKlaves();
    remote.resume();
  }
}

void detekceKlaves() 
{
  switch (val, HEX) 
  {
    case 0x807FB24D:
      Serial.println("Stisknuto PLAY");
      tone(2, fre);
      break;
    case 0x807FB04F:
      Serial.println("Stisknuto STOP");
      noTone(2);
      break;
    case 0x807F18E7:
      Serial.println("Stisknuto VOL+");
      fre += 10;
      break;
    case 0x807F906F:
      Serial.println("Stisknuto VOL-");
      fre -= 10;
      break;
    case 0x807F9867:
      Serial.println("Stisknuto OFF/ON");
      fre = 0;
      break;
