I am hoping that one of you might have extensive knowledge of C++ and creating an app using an IDE. I invented an app with million dollar potential but have not gotten it up and running let alone in the app store. I created it when I was high.
I want this app to simply display 3 pages of content in text format. Am I supposed to create a separate header file for the text and then write the code in another file? And use a member function to call the file that the text was saved on? If so, how do I do this?
I do not wish to take an istream just and ostream. Should I use the getline function? If so, what would that look like?
There's an example of reading (and writing) a file here:

You don't need to use header files for your program if it is only one file - you create headers to link small bits into one large program.
Probably you don't want your output displayed in a terminal window - for an 'app' it needs to be pretty with buttons and windows and such-like.
I don't know of a free (or not free) C++ IDE that does graphics. The Lazarus IDE creates windows and buttons by just drag and drop - a sort of alien technology in the C++ universe but it creates pascal code which is nice and easy to write but not as fashionable as C++. Lazarus is free and has served me well for the last 10 years.
Syne (or other) might be able to suggest a worthwhile IDE to create 'apps' for C++.

You'd think such a "genius" could figure out how to use Google and access all the answers already out there.
In fairness - if you don't know what you're looking for - you don't stand much chance of finding it. Servers, html, php, javascript, sql .. many many things you need to know to get an 'app' out there.
Not really. As long as you know which language you intend to use, any specific answers are pretty easy to find. Especially if you're a "genius."
All the basics of app design have been done before, and there's plenty of tutorials out there for just about any language.
I wonder if a genius can create something a genius doesn’t know how to create?

When you're high, you sure can believe it's possible.
Then you sober up...and start asking smarter people to help you.

So I will be storing string text in the app, as a string variable. So far I tried to use the getline function and word object but the IDE gave me a weird error message.
Can I do this all in one header file? If so, I want to know which preprocessor variable header guards I will be needing (#define, #ifdef, or #ifndef). And do we need to write these header guards out in each and every file we create? Also, what will I need to charge people for the app and as well, how do I get the app from the IDE to Android?
