For this lab it just has errors if someone can figure out why it would be very helpful.

What is the error?

Post your compiler output and put your code into code tags . Use the <> button on the right under format.

//Define Stuff
#define STARS "\t**************************************\n"
#define BOSS "\tKenneth\n"
#define PROTO "\tInternet Protocol Address Program\n"
#define EQUAL "\t=================================\n"
#define SLASH "\t//////////////\\\\\\\\\\\\\\\\\\\\\\\\\\\\\n"
#define SLASH2 "\t\\\\\\\\\\\\\\\\\\\\\\\\\\\//////////////\n"  
#define CONT "\tPress any key to continue...\n\n"
#define PERC "\t%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\n"

it is hard to tell but i think you have an odd number of '\' in the #define SLASH2, try adding or deleting one and see if that gets rid of this error:

h:\progc\lab 5.cpp(247) : warning C4129: '/' : unrecognized character escape sequence

EDIT: The error basically states that you have an escape '\' followed by an '/' which is not recognized as a vaild escape sequence i believe.
