Confused with a basic error

hey guys, i'm new stuff , learning @ uni. i'd appreciated anyones these error messages. great, , sorry novice level....

error messages
sketch_apr09a.ino:6:1: error: stray '\' in program
sketch_apr09a.ino:10:1: error: stray '\' in program
sketch_apr09a.ino:28:1: error: stray '\' in program
sketch_apr09a.ino:3:1: error: 'u2028' not name type
sketch_apr09a.ino:6:2: error: 'u2028' not name type




my sketch void setup() {
  pinmode(10, output); 
  pinmode(7, input);
  serial.begin(9600);
}


void loop() {
  int sensorvalue1 = analogread(a0);
  int sensorvalue2 = digitalread(7);


  if(sensorvalue2 == high){
    digitalwrite(10, high);
  delay(145000);} 
 for (int fadevalue = 255 ; fadevalue >= 0; fadevalue -= 5)
{analogwrite(10, fadevalue); 
  }
 
  if(sensorvalue1 > 500){
    digitalwrite(10, high);
  delay(145000);
  (int fadevalue = 255 ; fadevalue >= 0; fadevalue -= 5)
{analogwrite(10, fadevalue); 
  }
}
  else {
    digitalwrite(10, low);
  }


  serial.println(sensorvalue1);
  delay(1);       
}

you seem have control codes hidden in code supplied. removed them , compiles okay now. (note use of code tags make more readable)

code: [select]

void setup() {
  pinmode(10, output);
  pinmode(7, input);
  serial.begin(9600);
}

void loop() {
  int sensorvalue1 = analogread(a0);
  int sensorvalue2 = digitalread(7);

  if(sensorvalue2 == high){
    digitalwrite(10, high);
    delay(145000);
  }
  (int fadevalue = 255 ; fadevalue >= 0; fadevalue -= 5)
  {
    analogwrite(10, fadevalue);
  }
 
  if(sensorvalue1 > 500){
    digitalwrite(10, high);
    delay(145000);
    (int fadevalue = 255 ; fadevalue >= 0; fadevalue -= 5)
    {
      analogwrite(10, fadevalue);
    }
  }
  else {
    digitalwrite(10, low);
  }

  serial.println(sensorvalue1);
  delay(1);       
}
