I have this code:

header - test.h

Inside header I have some class Z and definitions of two functions test and test2 I call function test2 from test

void test2(Z z, Z const *za);

this is implementation of the function:

void test2(Z z, Z const *za){
  int i = z;         //this row works
  cout << i << endl;
}

I call it from test:

test2(z1, za1); // za1 is pinter to object and z1 is some object

but in my header I receive an 3 errors:

Multiple markers at this line
 - initializer expression list treated as compound 
  expression
 - `A' was not declared in this scope
 - variable or field `quiz2' declared void

can somebody please explain why? thanks in advance
