[C++]"post maker" help

[jerimo]

I am making a very simple "post maker".

I am not asking you to write the whole program for me!(mentioning since when people see a beginning like that they think the poster didnt do a thing)

The question that I have is if there is a way to make a thread keep "reading" even after a space is entered into the program?

I need this to make the person using the program to input the message and it will be added and formated automaticly to a HTML file.
But this doesnt work since it only registers the first word in the message.

Can no one help?

You must be talking about console program. I should assume you are using std cout and cin. So i will help with this.

If you have this kind of setup

string answer;

cout << "This is sample input name: " << endl;
cin >> answer;

that code will only allow 1 word no spaces. But if you use this instead you can use spaces

string tmp;

cout << "This is a even better sample input name: " << endl;
getline(cin, tmp);

[jerimo]

What is TMP?
sorry hadnt seen the string variable declaration.

but why do I need to put it in the () of the getline function?

[TheJunkie]

That is just a example. You said you want what they say to be put in the html file. So you need to make there input a string. So getline(cin, tmp) sets what they input to tmp. You could have it String answer or String input if you want it does not matter. If you still need help post some of you code here for me to see

I did what you told me to do but now it either gives an error or it doesnt put the info into the file at all.

Anyway to fix this?
(Don't have the code with me right now but will post it in not to long)

Posting the code will help; posting the error will help even more

I recently (last three years) wrote something like this and the logic I set it up to hand was to read until three carriage-returns were detected. I know it sounds weird but in this exact situation it was needed. So rather that just reading a cin >> stream I just read all keyboard input, accumulated it in a string, then for each carriage return I got I bumped a counter; if something else came in during this (character for example) I reset the counter to zero. BTW here is another hint: after you think you have detected the end of the message, walk the string you have accumulated and replace \n\r with <br> for the sake of the HTML.

I had written my own CMS which was an interesting project but eventually there were far better ones available for free and at the end of the day, I needed a tool I could use, not something else I needed to maintain.

This the code to my project, which doesnt work properly:

/*********************************************
Project: Post Maker
Description:
A fairly simple C++ program used to make posts
easily for non HTML programmers, those who
are can write directly in the file.
Programmer: James Oliver (AKA Jerimo)
*********************************************/
#include <iostream>
#include <fstream>

using namespace std;

char name[50];
string post;

void name_maker()
{
    ofstream chat ( "[TE]Chat.html" );
    //Checks to make sure that the chat file was opened successfully
    if ( !chat.is_open() )
    {
        cout << "A problem just happened" << '\n';
        cout << "Problem (35): File could not be opened" << '\n';
        return;
    }
    else
    {
    }

    chat << "<HR>" << name << "<HR>";
}

void write()
{
    ofstream chat ( "[TE]Chat.html" );
    //Checks to make sure that the chat file was opened successfully
    if ( !chat.is_open() )
    {
        cout << "A problem just happened" << '\n';
        cout << "Problem (35): File could not be opened";
    }
    else
    {
        //file can be used safely
    }
    name_maker();
    chat << post << "<br>";
}

int main()
{
    //to get the user's Name
    log_in_prot();
    //To get the user's Post
    cout << "Please enter your post, " << '\n';
    getline ( cin , post );

    //So it writes the input in the chat file
    write();
}

Not sure i understand what you meant when you described the system you used(Im only starting the advanced part of the tutorials on this site)

Noone has an answer to my problem

#include <iostream>
#include <fstream>
#include <string>
#include <stdlib.h>
using namespace std;

int main()
{
    int blanks=0;
    string post, name, line;
    ofstream outf("post.html");

    if(!outf)
    {
	cerr << "couldn't open file" << endl;
	exit(1);
    }

    //get name
    cout << "Enter your name: ";
    getline(cin, name);
    outf << "<HR>" << name << "<HR>" << endl;

    cout << "Enter your post (add 2 blank lines to finish) " << endl;
    //get post (reads till empty line)
    while(1)
    {
	getline(cin, line);
	if(line == "")
	{
	    blanks++;
	    if(blanks==2)
		break;
	}
	else
	{
	    blanks=0;
	    outf << line << endl;
	}
	outf << "<BR />" << endl;
    }
    outf.close();
    return 0;
}

Be more specific - WHY does it not work?
Is it a compile error (if so, what error)?
Does it not behave as it should when you run (if so, what is happening)?

[jeffcobb]

I had posted a whole load of logic and stuff up for this earlier and the last crash/restore ate it. Sadly I really don't feel like retyping all of that ATM...

[Elysia]

And so you thought you would make a reply about that you lost everything or you thought you'd reserve a post to type it up all again at a later date?

Yes. I was extremely tired when I wrote that, not that it is an excuse for being oblique. I guess I was saying I would retype it if no one else helped him/her in advance. Maybe 10pct of that was frustration of seeing his/her plaintive "why won't someone help me?" when I had put a decent amount of effort into doing so only to find it flushed down the toilet...
