Code for a 7-segment display sequence with LEDs

Projects Programming
1

Hi, i am really new at coding, so i don't really know how to deal with this. So i got this scheme which consists of 8 LEDs and a 7-segment display with a BCD decoder. I need 8 states each using the 8 LEDs to light up so they show a binary number for every state (state 1 lights up the LEDs to show 0001; state 2 1101;etc.) and the 7-segment display to show the number of the state ( 1,2,3,etc. until 8).
This is the scheme

So far i came up this but it's not working

const int A=13;
const int B=12;
const int C=11;
const int D=10;

int led0 = 9;
int led1 = 8;
int led2 = 7;
int led3 = 6;
int led4 = 5;
int led5 = 4;
int led6 = 3;
int led7 = 2;

void setup() {
  pinMode(A3, INPUT);
  pinMode(A, OUTPUT);
  pinMode(B, OUTPUT);
  pinMode(C, OUTPUT);
  pinMode(D, OUTPUT);

  pinMode(led0, OUTPUT);
  pinMode(led1, OUTPUT);
  pinMode(led2, OUTPUT);
  pinMode(led3, OUTPUT);
  pinMode(led4, OUTPUT);
  pinMode(led5, OUTPUT);
  pinMode(led6, OUTPUT);
  pinMode(led7, OUTPUT);
}

int count = 0; //variabila folosita pentru afisarea numarului

void loop() {
  if (digitalRead(A3) == LOW) //daca butonul e apasat
    {
    count++; 
    delay(200); //the delay prevent from button bouncing
    if (count == 10) //we want to count from 0 to 9!
      count = 0;
    to_BCD(); //convert to binary
    }
   
  if (count == 10)
    count = 0;

The digitalWrite highs and lows in the void loop represent each binary number i need the LEDs to show for each state.
