how do i use a single value to set mutable values in the scope?

Using Arduino Programming Questions
#1

Is it possible to set multiple value in the scope using just one for reference? Like what im trying to do in the example below.

thanks

int number_Pixels = 30;   // number of neopixels in strip

int RedPix[number_Pixels] = {};  //set the number of values for red LEDs in strip
int GreenPix[number_Pixels]={};  //set the number of values for green LEDs in strip
int BluePix[number_Pixels]={};   //set the number of values for blue LEDs in strip 


void setup() {
Serial.begin(9600); 
}

void loop() {
}
#2 
const int number_Pixels = 30;
#3

lol i was going try that but thought, why would a const int work any better! :slight_smile:

thanks dude

Because the compiler knows its constant, otherwise it could be changed by other modules
you've linked against. The linker checks const too I believe.
