Not reading .txt file

[Vector]

I have this code, and for some reason its not reading the text file..

#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>
#include <vector>

using namespace std;

struct myStruct
{
	int myIdent;
	float myPrice;
	float myMarkup;
};

char g_userOption;
char *g_myPtr;				// declaring my Global Varries
int g_myFindID;

int main ( int argc, char** argv ) 
{
	fstream inFile;			// using inFile as my file stream varaible
	string	sLine, theFile;	// using sLine as a string varrrie
	
	vector < string > vLineList;
	char myFile [ 1000 ];
	
	struct myStruct myProds [ 1024 ];		// declaring structure identifier that i can use
	
	char myStr[ 1024 ];
	char digits [ 1024 ];
	
	cout << "Enter a valid filename: ";
	cin >> theFile;   // <-this is probably whats wrong
	
	
	if ( !inFile )
	{
		cerr << "This is wrong" << endl;
		exit(1);
	}

	inFile.open("c:\\test.txt");
	inFile.open ( "test.txt", ios::out );  // i need the files output

		while ( getline ( inFile, sLine ) )
		{
			if ( sLine.length() == 0 ) continue;
			vLineList.push_back ( sLine );
				
				for ( int myNums = 0; myNums < vLineList.size(); ++myNums)
				{
					if ( sLine [ myNums ] == ',' ) break;
					
				
				}
					for ( int myDecs = 0; myDecs < vLineList.size(); ++myDecs )
					{
						if ( digits [ myDecs ] == ',' ) break;
						
					}
	
			
		}
	inFile.close();

	cout << sLine << endl;
	system("pause");
	return 0;
}

from what i can remember the contents of the file are stored in sLine;
I dont want my program to read only, test.txt but read every .txt file on the system

If you are including string, you might as well get rid of all the char[] arrays and just use std::strings. Any place you need a char array, just call the member function c_str().

[Bazzy]

You have (starting from line 34) this code:

	cout << "Enter a valid filename: ";
	cin >> theFile; 

	
	if ( !inFile )
	{
		cerr << "This is wrong" << endl;
		exit(1);
	}

	inFile.open("c:\\test.txt");
	inFile.open ( "test.txt", ios::out );

But it tests inFile before opening it (so will always fail).
After that inFile opens twice.

	string sLine = "";

	vector < string > vLineList;
	
	struct myStruct myProds [ 1024 ];		// declaring structure identifier that i can use
	
	char myStr[ 1024 ];
	
	cout << "Enter a valid filename: ";
	cin >> myFile;
	
	inFile.open( myFile.c_str(), ios::in | ios::binary);
	
	
	if ( !inFile )   // validate thefile
	{
		cerr << "This is wrong" << endl;
		return 1;
	}
		
		char bytes [ 4 ];
		inFile.read ( bytes, 4 );
		

		while ( getline ( inFile, sLine ) )
		{
			if ( sLine.length() == 0 ) continue;   
			vLineList.push_back ( sLine );		

			inFile.seekg ( 0, ostream::end );   // telling me how many lines inFile.
			cout << "Position is" << inFile.tellg() << endl;
		

	cout << sLine << endl;

		}
	inFile.close();		// close the file
	

	system("pause");
	return 0;
}

I was able to read the file properly...but what is my code doing?
has the data been allocated by using the vector <string> vLL?
Do i still need to use new, and delete to allocate further?

[Bazzy]

You need to give the number of elements to a vector:
vLineList.resize(/*number of elements*/); before using it.

[Zhuge]

You do not have to use resize, nor do you have to tell the vector how large to be. std::vector automatically handles allocating new space as you add elements.

[firedraco]

The only time you will HAVE to use it is when you are trying to have blank elements, i.e. vector with 3 elements, and you want to access element 5.
