+# GOAL 1: Printing the Digits
+
+## Challenge Steps
+
+1. Define a new placeholder type
+
+2. Create the digits from "zero" to "nine"
+
+      You can use these characters for the clock:
+
+      ```
+      Digit character       : █
+      Separator character   : ░
+      ```
+
+1. Put them into the "digits" array
+
+2. Print the digits side-by-side
+
+     1. Loop for all the lines in a digit
+
+     2. Print each digit line by line
+
+     3. Don't forget printing a space after each digit
+
+     4. Don't forget printing a newline after each line
+
+     EXAMPLE: Let's say you want to print 10.
+
+```

+       █   █ █     all the digits.
