Filling an Array with #defines

Using Arduino Storage
1

Hello,

cuerrently i am trying to set up an array.
To make programming more easy i want to fill it with defines.

My problem ist, that filling an array with defines doesn´t work at all.
error: stray'303'
Does anyone know if theres a way to do so?

void loop() {

Lose the semicolon

I have no idea what this is supposed to be.

I think it may be the name "ausgänge" which is causing the error, I tried changing it and this stopped the error 303.

you can't have an umlaut in a C++ variable name ( identifier) .. stick to just plain old ASCII (well not even all ascii, the dash is for minus, the dot has special use, etc...)

the spec says:

An identifier is an arbitrarily long sequence of digits, underscores, lowercase and uppercase Latin letters, and most Unicode characters. A valid identifier must begin with a non-digit character (Latin letter, underscore, or Unicode character of class XID_Start) and may contain non-digit characters, digits, and Unicode characters of class XID_Continue in non-initial positions. Identifiers are case-sensitive (lowercase and uppercase letters are distinct), and every character is significant. Every identifier must conform Normalization Form C.

Note: Support of Unicode identifiers is limited in most implementations, e.g. gcc (until 10).

It would make more sense if you make an array with all the pins and #define the indexes of the pins so when you need access to the pin you go

input_pins[WIRE1]

Make the array byte instead of int, I do not know of any board that has over 255 I/O pins.

The whole point of putting the pin numbers in an array is so you can avoid the long list of repetitive function calls:

void setup() {
  for (size_t i = 0; i < sizeof(ausgange) / sizeof(ausgange[0]); i++) {
    pinMode(ausgange[i], OUTPUT);
  }

  for (size_t i = 0; i < sizeof(eingange) / sizeof(eingange[0]); i++) {
    pinMode(eingange[i], INPUT);
  }
}

Hello
Or using a little bit C++:

void setup() {
  for (auto ausgang:ausgange) pinMode(ausgang, OUTPUT);
  for (auto eingang:eingange)  pinMode(eingang, INPUT);
}

Have a nice day and enjoy coding in C++.
