In C\C++ you can think of the "\" as sort of an signal to the compiler to
do something.  For instance when using the command:

printf("Hello World!\n\n");

You have two instances of "\n".  The "\" in "\n" tells the compiler that
escape character (the signal I mentioned before) is comming up.  So in
this case the "n" is the escape character that tells the
compiler/program to use a "newline."  

So when your compiler said that their was an unknown escape character, it
was complaining that it didn't know what you meant by "\P" --  Which of
course is nonsense as far as the compiler is concerned.

When you need to actually use the "\" character, you have to use "\\". 
So try:

strcpy( str, "C:\\PT" );


Hope this helps....
