Printing out the contents of a vector

[mcclit]

how to print out the contents of the vector? I have stored the contents of a file into a vector that also connects to a class, is it easier to print out a vector or print out the contents of a class? If there is anything else that I could fix, please let me know.Thanks

 #include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <sstream>
#include <cstdlib>
#include <algorithm>
#include <iterator>
using namespace std;

class expense
{
public:
	double c_price;
	string c_discription;

	
	string toString()
	{
		stringstream sout;
		sout << "price $(" << c_price << ") discription(" << c_discription << ")";
		return sout.str();
	}
};
int main(int argc, char*argv[])
{
	fstream fin;
	fin.open("expenses2.txt", ios::out);
	if (!fin) 
	{
		cerr << "Error in opening the file" << endl;
		return 1;
	}
	vector<expense> expenses1;
	expense temp;
	while (fin >> temp.c_price >> temp.c_discription) 
	{
	expenses1.push_back(temp);
	}

	string command;
	cout << "spend\nshow\namount >=\nsave file\nhelp\nexit" << endl;
	cin >> command;

	if (command =="show")
	{
		copy(expenses1.begin(), expenses1.end(), ostream_iterator<int>(cout, " "));
	}
	else if (command == "help")
	{
		menu();
	}
	else if (command == "spend")
	{

	}
	cout << argc << "  " << boolalpha << argcCheck(argc) << endl;
	if (argcCheck(argc) == false)
	{
		cout << "invalid command, please try again" << endl;
	}

	return 0;
}

    // *** print out the contents of the vector ***

    std::cout << "expense list:\n---------------\n"
              << std::fixed << std::setprecision(2) ; // two digits after the decimal point
    double total = 0 ;

    // range based loop: http://www.stroustrup.com/C++11FAQ.html#for
