declaring array

Projects Programming
1

Hi

I'm a novice in programming arduino.
I'm trying to copy a program in the book "le livre de projets arduino" sent with my arduino kit.

In page 83 the program begins by an array declaration :

int buttons[6];
int buttons[0] = 2;

this 2nd line returns an error : conflicting declaration 'int buttons [0]'

I don't understand this error.

Thanks for your help.

You have assigned two variables with the same name

I don't understand this error

I don't have the book, but the

int buttons[0] = 2;

is clearly nonsense.

buttons[0] = 2;

is valid, but only in a function.

You can declare arrays in several ways:
int myValues[6]; int myPins[] = {2, 4, 8, 3, 6}; int mySensVals[6] = {2, 4, -8, 3, 2}; char message[6] = "hello";

To assign a value to an array position ; eg position1, in the first example,you would just type myValues[1]=6;

Thanks all.

I tried to delete 'int', but it returns another error

int buttons[6];
buttons[0] = 2;

Error : 'buttons' does not name a type

The assignment of a value to a previously declared variable must be done in a function as previously mentioned in reply #2
