Stop running, adding and displaying files with C ++ delimiters

I have a program in which I capture and show with delimiters, I try to use tokens with the function strtok to separate the record by the same delimiters but at the time of printing it only prints the first record of the file and then stops work and I have no idea why, does anyone know what my error is?

According to me, the problem is with the show function, because it adds them well in the file.

Thank you very much in advance.
