I am getting error in If statement after (k nor i) "!&" need a ')'. But i Don't know how to fix this--

Pls help!

cout<< "\n\n (A and B) xnor((C nor A) nand(B xnor C))" <<endl;
	for( int i=0; i<2; i++){
		for (int j=0; j<2; j++){
			for( int k=0; k<2; k++){
		cout<< "A: " << i<< ", B: "<<j <<",C: " <<k<< "->";
				if((i&& j)^! (((!(k||i))!&(j!^k)))))
					'''''

}
}

I don't understand the meaning of line 14. I tried it in Visual c++ 2010 but it's giving error and I actually need 8 outputs of true false in this

See: http://www.stroustrup.com/C++11FAQ.html#for

For C++98, write classical for loops :

#include <iostream>

inline bool AND( bool a, bool b ) { return a && b ; }
inline bool OR( bool a, bool b ) { return a || b ; }
inline bool XOR( bool a, bool b ) { return (a+b) == 1 ; }
inline bool NAND( bool a, bool b ) { return !(a&&b) ; }
inline bool NOR( bool a, bool b ) { return !OR(a,b) ; }
inline bool XNOR( bool a, bool b ) { return !XOR(a,b) ; }

int main()
{
    std::cout << std::boolalpha ;

    for( int A = 0 ; A < 2 ; ++A )
        for( int B = 0 ; B < 2 ; ++B )
            for( int C = 0 ; C < 2 ; ++C )
                 std::cout << XNOR( AND(A,B), NAND( NOR(C,A), XNOR(B,C) ) ) << '\n' ;
}

In old school C++ you could also use this, although an index would probably be easier to read:

for( bool a = false, aa = true; aa != a; a = a || aa, aa = !aa )
                for( bool b = false, bb = true; bb != b; b = b || bb, bb = !bb)

Thanks All. It's good now
