Trying to create a program that recognizes a regular expression given in a DFA, and read a long substring contained in the text file. With every substring being the length of 3 and 5. What code do I include in my c++ program to read the DFA_text.txt file implemented in the program?

DFA RE(regular expression): 0(0+1)*0+1(0+1)*1

DFA should read the substring in the txt file:

1001001000000111110110110011111

from the DFA_text.txt and be able to display its position in the DFA.

DFA picture: represented by the RE

How the program should look when done correctly

Need help figuring out the code so it can read the txt file in c++
