Error during ( gcc 10.c -o 10 )

so many lines code error, just showing last and first lines

The C code has several errors here. Don’t focus on the warnings in this, focus on the red error part. Start from the very beginning - “Unknown type name 'Exploit” so it is not recognizing Exploit. Check what the code is and why it is giving that error, is something not included correctly? Read the entire C code and understand it.
