I have a Prolog file (Hanoi.pl) containing the code for solving the Hanoi Towers puzzle:
hanoi( N ):-
move( N, left, middle, right ).
move( 0, _, _, _ ):-
!.
move( N, A, B, C ):-
M is N-1,
move( M, A, C, B ),
inform( A, B ),
move( M, C, B, A ).
inform( X, Y ):-
write( 'move a disk from ' ),
write( X ),
write( ' to ' ),
writeln( Y ).
I also have a C++ file written in VS2008 IDE:
#include <iostream>
#include <string>
#include <stdio.h>
#include <stdlib.h>
using namespace std;
#include "SWI-cpp.h"
#include "SWI-Prolog.h"
predicate_t phanoi;
term_t t0;
int main(int argc, char** argv)
{
long n = 5;
int rval;
if ( !PL_initialise(1, argv) )
PL_halt(1);
PL_put_integer( t0, n );
phanoi = PL_predicate( "hanoi", 1, NULL );
rval = PL_call_predicate( NULL, PL_Q_NORMAL, phanoi, t0 );
system( "PAUSE" );
}
How can I consult my Prolog source code (Hanoi.pl) from within my C++ code? Not from the Command Prompt - from the code, something like include or consult or compile? It is located in the same folder as my cpp file.
Thanks,
