problem with argument types

[icemanfan]

#include <fstream>
#include <iostream>
#include <string>

using namespace std;

void inputFileInfo(string&, int&);

void displayFileInfo(string&, int&);

int main()
	{
	ofstream fsOut;
	
	string fileID;
	char str[100];
	int lineCount = 0;
	int currentLine = 0;
	
	inputFileInfo(fileID, lineCount);
	
	fsOut.open(fileID, ios::out | ios::app);
	while(currentLine <= lineCount)
		{
		cin.getline(str, sizeof (str));
		fsOut << str << endl;
		currentLine++;
		}
	fsOut.close();
	
	
	return 0;
	}

void inputFileInfo(string& fileName, int& lines)
	{
	cout << "Enter name of file: ";
	cin >> fileName;
	cout << "Enter number of lines to add: ";
	cin >> lines;
	}
	
void displayFileInfo(string& fileName, int& lines)
	{
	cout << "File: " << fileName << endl;
	cout << "Number of lines added: " << lines << endl;
	}

I know why this code doesn't work: fsOut.open can't take a string as an argument. But although it can take a character array as an argument, my functions (most importantly, inputFileInfo) won't work because they take strings by reference. Is there a way to pass character arrays by reference, or a better solution to the argument incompatibility?

C++ strings have a method that converts them to C-style strings. Try fsOut.open(fileID.c_str(), ios::out | ios::app);

Thanks. That solved the problem quite nicely.
