i have an error
but i dont understand and i have no skill in electronics and i have an arduino uno r3 from creation crate(not sure if that changes anything)my project is a memory game and here in my code so far. thanks!

const int button1=2;
const int button2=3;
const int button3=4;
const int button4=5;
const int led1=7;
const int led2=8;
const int led3=9;
const int led4=10;
const int buzzer=12;
const int tones[]={1900,1600,1300,1000,3200};
int buttonState[]={0,0,0,0};
int lastButtonState[]={0,0,0,0};
int buttonCounter[]={0,0,0,0};
int game0n=0;
int wait=0;
int currentLevel=1;
int dlay=500;
int ledTime=500;
int n_levels=10;
int pinAndTone=0;
int correct=0;
int speedFactor=5;
int ledDelay=200;

void playTone(int tone(), int duration) {
for(long i=0; i<duration*1000L; i+=tone()*2)
{
digitalWrite(buzzer,HIGH);
delayMicroseconds(tone);
digitalWrite(buzzer,LOW);
delayMicroseconds(tone);
}

Please post your full code between
** **[code]** **
and
** **[/code]** **
.

Please provide the full error message; if the above is your full code, you're missing setup() and loop().

3 
void playTone(int tone(), int duration) {
  for(long i=0; i<duration*1000L; i+=tone()*2)

Why do you have parenthesis after tone?

okay now i get the following error message

/tmp/961973469/build/../../core/core_Intel_arc32_arduino_101_ce7885b3d89440f4810c5db77fdcac10.a(main.cpp.o): In function main': /home/builder/.arduino15/packages/Intel/hardware/arc32/2.0.4/cores/arduino/main.cpp:43: undefined reference to setup'
/home/builder/.arduino15/packages/Intel/hardware/arc32/2.0.4/cores/arduino/main.cpp:47: undefined reference to `loop'
collect2: error: ld returned 1 exit status
exit status 1

so what does it mean?

Your sketch does not contain the setup() and loop() functions.

cool thanks

I suggest that you start with some example sketches and see if you can figure out what is common between all of them. You don't even have to compile them.

k thx for the tip

i have another error
error(incompatible types in assignment of ‘long int’ to ‘int [(((sizetype)(((ssizetype)n_levels) + -1)) + 1)]’)

updated code:

pinMode(button1,INPUT);
pinMode(button2,INPUT);
pinMode(button3,INPUT);
pinMode(button4,INPUT);
pinMode(led1,OUTPUT);
pinMode(led2,OUTPUT);
pinMode(led3,OUTPUT);
pinMode(led4,OUTPUT);
pinMode(buzzer,OUTPUT);
}
void loop(){
int n_array[n_levels];
int u_array[n_levels];
int i;
if(game0n==0){
for(i=0; i<n_levels; i=i+1){
n_array*=0;*
u_array*=0;
n_array=random(0,4);
_ }_
_ game0n=1;_
_ }_
_}*_
*note this code is not complete

11

Maybe something like

n_array[i]=0;

Why is your code partially in italics? Use code tags as explained in reply #1.

12

I ask again, please post full code.

13

Lets not do this.

Post the entire well formatted code, in code tags, please?
