Text Files

[compman9902]

I know that this subject is a little drawn out, but I do need some help.
I have searched google for a while but still can't seem to get an answer.
All I need is the code for a few things (links to tutorials will do fine as well).
1.) Creating a text file at a user-defined location and then filling it with a few lines of pre-assigned numbers
2.)Reading a text file at a user-defined location and then creating a second text file using the original file name at the same location (ex. Reads ex.txt and makes Eex.txt)
That is all I need. Here is what I'm working with:

string locationOne;
string locationTwo;
string nameOne;
string nameTwo;
string filler;
cout << "Please Enter The Location Of The File You Want To Write To: " << endl;
cin   >> locationOne;
cout << "Please Enter The Location Of The File You Want To Read: " << endl;
cin  >> locationTwo;
cout << Please Enter The Name Of The File You Want To Write To: << endl;
cin  >> nameOne;
nameTwo = "E" + nameOne;
 

locationOne = The File To Write To
locationTwo = The File To Read
nameOne = The Name Of The File To Write To
name Two = The Name Of The Modified File To Write To
filler = What I put in the text files
Please either give me an example using the above variables or give me a link to a helpful tutorial
Thank You

I have and I have to tell you..I don't really understand it.
Every time I try to do this:

ofstream myfile;
myfile.open (locationOne);
myfile << "Writing this to a file.\n";
myfile.close();
 return 0;

I get an error on the "myfile.open (locationOne);" part.

This is because your compiler expects a character array (cstring) in the open() command rather than a string. Instead of

myInputStream.open(myString);

write

myInputStream.open(myString.c_str());

and the error should be fixed.

That only answers a few of my questions. Also, please tell me how to open the file save and file open dialogs
Thanks

you can use myInputStream.getline() to read in lines from your file. you can then feed them into a new file that you create in much the same way as the first.
