Using Arduino Programming Questions

i would like to ask if this simple code is correct, any correction will be much appreciated. many thanks!
here it goes, i connected all the 9 cathodes together and repeated the process 3times just like the ones shown in youtube;
all 27 anodes connected together forming 9 pins , 3 levels, right?

int pinarray[9] = {1,2,3,4,5,6,7,8,9); //pins 1-9 on the arduino are each connnected
// to the 9 anodes
int pin10 = 10; // pin 10 on the arduino is connected to cathode first level
int pin10 = 11; // pin 11 on the arduino is connected to cathode 2nd level
int pin10 = 12; // pin 11 on the arduino is connected cathode 3rd level
int x;

void setup(){

pinMode = (pinarray[9] , OUTPUT);{

pinMode = (10 , OUTPUT);
pinMode = (11 , OUTPUT);
pinMode = (12, OUTPUT);

}

void loop(){

for(x= pinarray[9]; x<10; x++);{
digitalWrite( pinarray[9], HIGH);
digitalWrite(10,HIGH);
delay(100);}

for(x= pinarray[9]; x<10; x++);{
digitalWrite( pinarray[9], HIGH);
digitalWrite(11,HIGH);
delay(100);}

for(x= pinarray[9]; x<10; x++);{
digitalWrite( pinarray[9], HIGH);
digitalWrite(12,HIGH);
delay(100);}

digitalWrite( pinarray[9], LOW);
digitalWrite(12,LOW);
delay(100);

digitalWrite( pinarray[9], LOW);
digitalWrite(11,LOW);
delay(100);

digitalWrite( pinarray[9],LOW);
digitalWrite(10,LOW);
delay(100);

}

is this the right code to light all pins simultaneously from level 1 to level 3
and eventually turning it off? tnx

No, it isn't. When you have something that will at least compile, come on back.

If the problem is that you don't understand a compiler message, show us the message and the code.
