a console application in C++

[arnuld]

i want to create a console application in C++ . what can be the 1st
step ?

NOTE: i did use Google but that gives me some VC++ based links using
non-standard libraries.

Download a compiler.

Download a compiler.

seems like you did like my question. may be it is OT but i wanted to
write a console application in C++ without using any non-standard
libraries. i already have the compiler as i have Arch GNU/Linux: GCC
4.2.1

What do you mean by console application? Roughly speaking there are two
kinds of applications, console and GUI and I don't think you've written
any GUI applications yet, which means that what you've done so far are
console applications.

If the input/output capabilities of cin/cout are not enough for your
needs you'll have to use some other, platform specific libraries since
there's nothing more advanced in standard C++. If this is what you want
ncurses might be worth looking into.

What is your definition of "console application"? Is this a "console
application"? In a shell, do:

$ cat hello.cpp
#include <iostream>

int main()
{
std::cout << "Hello world" << std::endl;
}

$ g++ -std=c++98 -pedantic hello.cpp -o hello
$ ./hello
Hello world

Note: the "-std=c++98 -pedantic" flags ensure that you are compiling
according to the current C++ standard without any GCC-specific extensions/
restrictions to the language.

sorry , i was at fault of not being clear. actually what we see at our
colleges/universities is theoretical foundation like make a programme
do this and do that. an average student from an average university
(unlike MIT, CMU etc) reads books and does the things and when he
enters in to the real-life software work like doing a job in industry
or working directly with customers, he gets shock at first because it
is *different*. same happened with me.

i want to create some console programme, i mean, anything that can be
called practical work and but which is general and approachable enough
for a fresher like me..

any ideas on that ?

Lionel, i use this.

g++ -ansi -pedantic -Wall -Wextra file.cpp

tell me if it is ok ?

if you get the binary than is ok. On the other hand, if you are using
*nix based OS, man gcc or man g++ may help.

I used to use -ansi rather than -std=c++98 until it was pointed out to me
(on this ng) that -std=c++98 is probably more appropriate; ISO is an
international standardisation organisation, while ANSI is US only.

Apart from which I've actually just had a look at the GCC manual and it
doesn't say what -ansi does (if anything) for C++ - it only specifies the
ISO 1990 C standard, apparently...

You need a compiler, linker, and the standard libraries.

You need some kind of ability to produce a source file.
That can be any convenient text editor that lets you
make a text file that your compiler can accept.

But this is off topic here. You need specifics on
how to run your local program, platform, compiler, etc.
If you have *language* questions, ask away. But how to
get your compiler etc. to produce an executable is off
topic here.

Look for help files or other docs with your compiler.
Look for news groups that have your compiler's name
in their name. Google for tutorials specific to your
particular compiler and platform.

From the Solaris man pages:

-ansi
In C mode, support all ISO C90 programs. In C++ mode,
remove GNU extensions that conflict with ISO C++.

Sure. The first is that you aren't going to get anywhere writing
vague and incomprehensibl e questions in a newsgroup. If you want to
write a program then write one. Do the exercises in a textbook.
Solve a problem. Or, if you're beyond more trivial matters and yearn
for something more like real-world experience, find an open source
project. There are plenty of places where open source apps can be
found. Start with a smaller one, and get familiar with the code --
add a feature, fix a bug, whatever.

Find a problem that your program should solve. Without a problem, it is hard
to tell whether the program is correct/useful.

NOTE: i did use Google but that gives me some VC++ based links using
non-standard libraries.

Which libraries you will need is something to be determined once you know
what you want the program to do.
