When trying to compile the program

class A {public:	void a() {};};class B: public A {public:	void a(int n) {};};int main(void){	B b;	b.a();	return 0;}

I get the error message:

test.cc: In function `int main()':
test.cc:15: no matching function for call to `B::a ()'
test.cc:8: candidates are: void B::a(int)

I believe the code is correct (so do all my colleagues). Changing the method name to 'b()' (or anything else) fixes the problem.  The code snippet does not exhibit good programming style, but nonetheless it seems to be correct.

C++ books in my reach gave no help on the subject.
