so heres the deal im supposed to implement some functions given this header file:
1) header file:
#ifndef MailingLabel_H
#define MailingLabel_H
class MailingLabel{
public:
MailingLabel(); // default constructor
MailingLabel(char*,char*,int);
MailingLabel(MailingLabel&); // copy constructor
~MailingLabel(); // class destructor
MailingLabel& operator = (const MailingLabel&);
void input( istream&);
void output( ostream&) const;
private:
char* name;
char* address;
int zipcode;
};
What im supposed to implement is:
Input Function - this function is not a constructor - it is working with an object. You also hve to make an assumption about the size of the input data - so that you can make a buffer ( array of temporary info) to hld characters. The input function has to delete the old data from the object, read the new data into a buffer, then get the actual size of the data, make storage,,point to it, and copy the data into the object. Be careful not to delete null pointers.Header File
How do i do all of this if its just a input function? Arent only inputting commands (cin, etc.) allowed in this only?
