Drawing character inside rectangle

Question

Hi!
I have the following problem. I have a string and my task is to be able to draw every character of the string in every rectangle. For example I have a string:
String = ("GCATCGCAGAGAGT");
So now I will have 14 characters inside 14 rectangles. My question is how to do that? Please help me to solve it.

Answer 1

This is my code. There's still error in it. It can not show the rectangle and also the characters. Could you fix my code? I am still a beginner in this field
I am sorry if my code is not formatted as well, because I am a new comer in this forum. So please help me to solve my problem, I expecting a lot from you.
