int myFunction1(int x)
{
  return x + 10;
}

int myFunction2(int x)
{
  return x * 10;
}

int execFunction(int(*function)(int), int x)
{
  return function(x);
}

int main()
{
  int y = execFunction( myFunction1, 10 );
  cout << y << "\n";

  y = execFunction( myFunction2, 10 );
  cout << y << "\n";
  return 0;
}
