Please use the "#" CODE TAGS toolbutton to post code so it looks like this:

int ledPin[] = {7,8,9,10};
int Anumber= 2;
int Bnumber = 3;
int Cnumber = 4;
int Dnumber = 5;
int a;
int b;

void setup()
{
   pinMode (Anumber, OUTPUT);  
  pinMode (Bnumber, OUTPUT);
   pinMode (Cnumber, OUTPUT);
    pinMode (Dnumber, OUTPUT);
  for (int i =0;i<4;i++)
  {
    pinMode(ledPin, OUTPUT);
  }
}

void loop() {
 displayBinary(3);
}

}
void displayBinary(byte numToShow)
{
  for (int i =0;i<4;i++)
  {
    if (bitRead(numToShow, i)==1)
    {
      digitalWrite(ledPin, HIGH); 
    }
    else
    {
      digitalWrite(ledPin, LOW); 
    }
  }

void (); {
  a = 5;
  b = 1;
digitalWrite (Anumber, HIGH);
delay(a);
digitalWrite (Anumber, LOW);
delay(b);
digitalWrite (Bnumber, HIGH);
delay(a);
digitalWrite (Bnumber, LOW);
delay(b);
digitalWrite (Cnumber, HIGH);
delay(a);
digitalWrite (Cnumber, LOW);
delay(b);
digitalWrite (Dnumber, HIGH);
delay(a);
digitalWrite (Dnumber, LOW);
delay(b);
}
