Thread: vector sort

Here is a shortened version of my code (shortened and placed in one file). It's supposed to read in files like:
1234,smith,bob
1234,smith,adam
1234,jones, carl

then does a bunch of validation whcih I haven't included.

and spit out
1234,jones, carl
1234,smith,adam
1234,smith,bob

The problem is it doesn't like my record* in the less1 line.

I know everything is based on std::vector<record*> schoolvector
and I think the less1 sort issue needs the values for record, not hte pointer. I can't figure out how to give it what it wants.

References and pointers work faster but I can't figure out how to work those in conjunction with my sort.

-nearing my end. (I thought I was doing so well)

Code:

#pragma warning( disable : 4786)
#include <iostream>
#include <vector>
#include <algorithm>
#include <functional>
#include <fstream>
#include <string>
#include <sstream>

class record
{
public:
	std::string corp;
	std::string lastname;
	std::string firstname;
	friend bool less1(const record& a, const record& b);
};

//exception struct
struct read_exception { };

//populate vector from file
void initialize_vector(std::vector<record*>& vec);
//defines sort order
inline bool less1(const record& a, const record& b);
      
void main()
{

	//identify schoolvector based on record class/struct
	std::vector<record*> schoolvector;
	//populate from file
	initialize_vector(schoolvector);
	std::cout << "initialized." << std::endl;

	//sort by specific column order
	std::sort(schoolvector.begin(), schoolvector.end(), less1);

	//view output to show that it's sorted.
	std::vector<record*>::iterator start = schoolvector.begin();
	std::vector<record*>::iterator stop = schoolvector.end();
	for( ; start != stop; ++start)
	{
		std::cout << (*start)->corp << "," 
<< (*start)->lastname << "," 
<< (*start)->firstname << std::endl;
	}

}



void initialize_vector(std::vector<record*>& vec)
{
	
	std::string sdetailline;
	std::string tempstring;
	int colcount = 0;

	//assign tmp as pointer to record struct
	record* tmp;
	std::ifstream fin;
	fin.open ("zz.csv", std::ios::in);    
	if(fin.fail())
		{
		throw read_exception();
		}
	while (std::getline(fin, sdetailline))
	{
		int colcount = 0;
		tmp = new record;
		std::istringstream istrLine(sdetailline);
		while (std::getline(istrLine, tempstring, ','))
		{
			if (tempstring == "")
			{
				tempstring = " ";

			{

				tmp->corp = tempstring;
				break;
			case 1:
				tmp->lastname = tempstring;

				tmp->firstname = tempstring;

			}
		colcount++;

		vec.push_back(tmp);
	}
	fin.close();
