Thread: Custom String Class member functions

Ok I posted something earlier about this but was asking for too much at once so I am going to try to break this up now as I find myself needing help.

Being a beginner to C++, I am right now stuck on declaring the member functions in the header file.

Right now I need to create an assign member function that accepts a string object parameter. This checks for the assignment to itself and then assigns a new value to this String from the parameter String, making a deep copy of the character data.

So in my header file this would be declared as something like:

Code:

#ifndef _TSTRING_H
#define _TSTRING_H

class TString { // Prefix with 'T' for uniqueness
public:
  TString(const char *pText = 0); // default ctor
  TString(const TString &);
  ~TString();

  int length()
  {
	  return mLength;
  }

  const char *asChar() const;

  void assign(string obString); //<---- member function in question

private:
  int mLength; // length of char data (not including null byte)
  char *mpText; // pointer to dynamic char data in heap
};

#endif   // _TSTRING_H

im going to worry about defining the member fuctions after i finish declaring them in the header, so im just looking to get this part done right now.

o and to add to this. the next step calls for another assign member function this time that accepts a character pointer. this one checks for assignment to self, and assigns a new value to this string from the parameter character array.

is it possible to have two member functions with the same name in the header file?

ok so now i think in accordance to the second post the two assign member functions would be declared like this:

Code:

  void assign(string obString);
  void assign(const char *);
