[C++] confronto file di testo

[athebustop]

ciao a tutti,

come faccio a confrontare questi tre file allegati tramite if..else?
per esempio due hanno una riga che l'altro non ha.. come faccio a saltare di riga in riga e confrontare quello che trovo con quello che mi aspetto?

grazie

---[An error has occurred and this utility has aborted]---------

This error was generated by a USCIF adapter library
that is currently accessible to TI's USCIF driver.
The decimal value is: `-701'.
The title string is: `POD_ERR_MAP1'.

The explanation is:
This error resulted from the first attempt to access the
DSK hardware. The status from the DSK was erroneous. The
most common causes of this problem are:
1. No power to the DSK
2. The cable is disconnected from the parallel port
3. The DSK is locked up and requires a power cycle

---[An error has occurred and this utility has aborted]---------

This error was generated by TI's USCIF driver.
The decimal value is: `-110'.
The title string is: `SC_ERR_OCS_ALREADY_OPEN'.

The explanation is:
This utility was able to open the controller, but
the controller is already in use by Unified-SCIF.
You must exit other debuggers and utilities that
use Unified-SCIF because this utility must be the
only client of Unified-SCIF and the controller.
