This is a good.effort. d big issue is how it gets input. until ur program starts by readg input and parsing dm for token, it is not real world program.Nice effort though.

Files(i.e. disk),console, and printer are examples of devices.

cout writes to stdout by default which is d console. It can be redirected to write to any other output device.

If u wish to write to a device and retrieve later dn dt device must neccesatily be a file.
thanks bro. But i did not understand the part about stdout being a console because i have seen some programs in c++ where stdout is not used. Exactly what is the purpose of this console (stdout). I also don't understand the dn dt, are they standard c++ words or its your way of writing then that, because strictly speaking i have seen somewhere dt was used as a standard c++ word just like int. So furnish me please. Bros, i have seen and respect that you are a progressive c++ expert, and thank you for that.

See this:
https://en.m.wikipedia.org/wiki/Console_application


I know dt the ofstream object is a stream. it is like an interface btw a program and and a device. When u write with ofstream u are not writng to a devicr. You are writing to a stream. Files and printers are examples of devices.



POST EDIT:
Download and read ; C++: The Complete Reference by Hebert Sheildt 4th Edition.

U can also check my post in my main nairaland account - mnairaland
ok thanks bro. But when i read the link, being a beginner programmer as i am, i feel like ms word is a type of console application. Please help me understand there, thank you.

It seems you are a beginner programmer. I will advice you get a good c++ book as Jacob Suggested. These things are not as complex as you think.
C++ is not a language u rush over. just take your time and learn the damn Beast !
yeah, i guess so...... I am afraid i am going to spend the better part of my time trying to grasp c++, and by the time i reach......yrs i def must an expert. I tried reading the deitel and harvey text book, but man, i could not understand the jargon, but at least it got me thinking otherwise, anyways thanks bros.

yea, it isn't strange to feel that way. Every Pro u see speaking Codes was once in your stage. Just relax, define your goals and work your way to the top . its a step by step matter. Do check the book Jacob05 recommended, it will really get u started with Programming in general !


Note: read less and Practice more !

Exactly... And don't forget to study source codes you might come across

Friend: cout is a.stream. it can be linked to any device.The device dt cout is currently linked to is called stdout. it could be a printer, file, console or any other device.
Compiler writer usually set d console as d divice dt cout is currently linked to i.e. they link cout to d console by default.You can change dt if u wish.

Generally. There two types of applicatns : console and non-console.

A console applicatn is an application whose user output is directed at d console.
A non-console application is an application whose user output is not directed to d console.Usually their output is direct to a window. While windows are graphical output envirinment consoles are not.

Using windows as an example, there two types of applicatns: console applications and windows appkicatn.MS Word is.a. windows applicatn.

My professional advice to u is to stop askg these elementary questns. Get a book and read.That is.a professional advice.

Download and read :Beginnes Guide to C++ by Herbert Sheidt.

Note: There are good and bad books for learng C++. The ones i have recommemded are good books.

ok, thank you. Suppose i return 0,what part of the code you suggest i put the command

You can call the system function and pass the commands as parameters.
system("notepad /p your_file.txt");

Remember to #include <stdlib.h>
You'll need that for the system(); function.

Thank you, i will try that out.
