    Reading postal address using cout

    I have a text file addresses.txt which contains a postal address as a single record
    i.e
    24 Church Street McClerance Close California 5084 .. record 1
    .................................................. ................................. record 2
    24 Church street is to be read to variable line1
    McClerance Close is to be read to variable line2
    California is to be read to variable city
    5084 is to be read to variable zip

    How do i read this at once to all these variables?

    You should put ,'s in the address and read up to them as substrings. So you'd read between the square brackets then.
    [24 Church Street], [McClerance Close], [California], [5084]
    So you could then use getline and use ',' as a deliminator rather than '\n'

    I used commas, and here's how am reading them, but i get a runtime exception on the first getline

    Code:
    std::istream& operator>>(std::istream& in, Address& address)
    {
    	char *fline="";
    	char *sline="";
    	char *tline="";
    	char *cty="";
    	char *cde="";
    	
    	in.getline(fline, 100, ','); /* This throws an exception */
    	in.getline(sline, 100, ',');
    	in.getline(tline, 100, ',');
    	in.getline(cty, 100, ',');
    	in.getline(cde, 5);
    
    	std::string firstln(fline), secondln(sline), thirdln(tline), city(cty), code(cde);
    	address.setAddress(firstln, secondln, thirdln, city, code);
    
    	/*
    	in >> fline;
    	in >> sline;
    	in >> tline;
    	in >> city;	
    	in >> cde;
    	*/
    
    	return in;
    }

    Read especially the two first topics.
    Use std::string and std::getline.

    You also seem to have been poisoned by some members or some tutorials...
    C++ programmers should use T* and not T *!

    fline, sline tline .. are string literals that cannot be modified.
    Why don't you use the std::string version of getline ?
