errors with assert()

[grcunning]

We are writing our own string class(mystring), and I am having a problem with my operator[] overload. The function works fine, but we are supposed to use an assert to insure that the position passed to the function is less than the length of the array.

char mystring::operator [ ](size_t position) const
	//Precondition: position < length()
	assert(position < length);
	{
		char result;
		result = *(sequence+position);
		return result;
	}

length is a private member variable, position gets passed to the function, and both are of type size_t. They should both be in scope. The errors I get are:

all errors are on the line assert(position<length):

error C2091: function returns function
error C2065: 'position' : undeclared identifier
error C2597: illegal reference to non-static member 'mystring::length'
error C3867: 'mystring::length': function call missing argument list; use '&mystring::length' to create a pointer to member
error C2568: '<' : unable to resolve function overload

Shouldn't the assert be placed inside the {} ?

char mystring::operator [ ](size_t position) const
	//Precondition: position < length()
{
  assert(position < length);
  char result;
  result = *(sequence+position);
  return result;
}

duh! That's why I love this site. I had looked at it for too long without seeing the obvious. Thanks
