c++ consle app HELP
IS there a way too make that if the user runs a program the programe makes a file and the user then define whats written in the fileIF you dont get it I think this should help:
you run the app
the consle app makes a file
you name the file
you write whats supposed to be in the file
the app saves it
and you type a command to veiw it
Of course it is. This is programming, not baby-sitting.
You run the app.
Console app asks for filename.
Console app stores input.
Console app creates new file from input.
Console app asks for the information to write to the file.
Console app stores the input.
Console app writes the input to the file.
Console app closes file.
Console app asks you what you want to do.
Console app awaits input.
User enters some commands.
Console app parses the commands and does what the user wants.

No, I'm not here to do homework.
You write the code.
But if you get stuck, then you ask specific questions about what you have problems with.
This always makes me wonder... why do you choose to pick up programming if you don't want to do the programming? You'll benefit more by ATLEAST attempting it. Good luck.
This isn't homework but I am stuck really all I need to know is how to put the file name that the user imported into the ofstream line is it some thing like this
Note:that was a guessCode://code { char filename; //code ofstream a_file("filename") //code }
It's not homework, but you're trying to get us to do it for free and you "need" it..... right. Have a nice day.
What you are describing is the kind of thing easily done in a shell/command line interpreter. So that makes me think, why would you want to do this ? On a POSIX-compliant (or mostly POSIX-compliant, anyway you only need the 'cat' utility, so you would be fine if you are on Windows and have cygwin, and anyway I'm quite sure there's something equivalent native to Windows), it would looks like this:
But if you still want to write your own program, well, I'm feeling lazy, so I'm just going to give you this reference. But since there's quite a good amount of info in there, this could be a bit confusing for a newcomer.Code:$ cat - > filename You enter your text here. It can be multiline. When you are done, you press Ctrl+D. (or maybe Ctrl+Z on Windows) $ cat filename
I hate real numbers.
It really isn't homework just a projcet I'm making for fun I figured out parts of it but I just don't know how to get what the user inputed into the ofstream line:
What I'm talking about:
Code:ofstream a_file( "name of file" ) ---------------------^________^ How do I get what the user inputed there?
What's wrong with storing it in a variable?
You should have learned this quite early, usually it's one of the first things you learn.
I've narrowed it down for you, if you can't find it here then all hope is lost for you:
http://www.cplusplus.com/doc/tutorial/basic_io.html
Give that a read.
Note: I don't really care if it's homework or not, but the fact is that you're trying to extract code from us for a very simple thing. And that is bad in my eyes and others because we want YOU to learn how to do this, which is why we usually refuse to write the code for you, but help you through coding it yourself.
It helps you become a better programmer.
That's odd. If you got to the point the user made an input, you already have it stored in a variable. No other way around it as far as I know. That's how cin works.
So, you just use that variable with ofstream, replacing the meaningful argument with the variable name.
What exactly are you using to learn C++? Seems to me something is amiss there if they don't explain this. You might want to find a better tutorial.

I think I fugured it out!!! is it like this?:
????Code://code { char filename[20]; char filetxt[5000]; //code // of stream declaration ( << filename << ); a_file( << filetxt << ); // code }
I can see the A+ coming a mile away.
