i havent done this before, but how would i make a CSTRING of a filename? i am looking @ about.com tutorial, but is very confusing.

>class cFILENAME:public cSTRING
What good is inheritance here? Containment would be much better as you don't use anything that requires internal knowledge of cSTRING, and a filename is only represented by a string, it isn't a string in and of itself logically:

Code:

---

class cFILENAME
{
  cSTRING FName;
public:
  cFILENAME();
  cFILENAME(char *pszStr1)
    : FName(pszStr1)
  {}
  cFILENAME(cSTRING &rhs)
    : FName(rhs)
  {}
  // No destructor needed

  const char* getExtension() const;
  cFILENAME& toUpper();
  cFILENAME& toLower();

  char *getFName1()
  {
    return FName.getName1();
  }
  char *getFName2()
  {
    return FName.getName2();
  }
};
