HI RALF,

what do you think about that:

double H( int x )
{
     // do something
}

double V( int x, double (*f)(int) )
                          ^
                          * This is a pointer to a function getting an inte-
                          * ger and returning a double
{

     return f( x );
}

int main( void )
{
     printf( "The result is %f\n", V( 10, H );
                                          ^
                                          * This is the adress of function H

     return 0;
}

hope this helps

Martin
