New to C++ help

[mehdij23]

hey every one my name is mehdi and i just started using turbo c++, till my c++ from microsoft arrives. Is there a difference in terms of coding in C++ than trubo C++?


Please give me a feedback because when i put this in Turbo c++ it tells me i have 6 errors.

My Code

#include <iostream>
using namespace std;
int main ()
{
cout <<"hello world";
return 0;
}


Please help me out.....

Use a decent, standards-compliant compiler. Like GCC. Turbo C++ is old, and does not comply with modern C++ standards.

hi guys. im new to c++ but ive been doing turing for a few months now. i started to get back into c++ today i downloaded and installed dev c++ and i tried this code out of a book my dad gave me today

# include <iostream.h>
# include <conio.h>

void main ()
{
float x , y , s ;
cout << "Enter the 1st number ";
cin >> x ;
cout << "Enter the 2nd number ";
cin >> y ;
s = x+y
cout << "x= "<<x<<" y= "<<y <<" x+y = "<< s << endl ; getch () ;

it shows many errors first one being conio no such directory found

can someone plz help me out on how to setup dev c++ so it uses the right directories..thanx a lot guys

also i have linux fedora core 4 running on vmware with win xp as host machine with all the programing utilities pre-installed on it..what program can i use there to learn c++ ?

Using Dev-C++ is a mistake. It's buggy. Just use the command-line tools. They work reliably.

Secondly, the code you were given is old and non-standard. Learn standard C++ if you must learn C++ at all. (C++ is an atrocious intro language)

ye thats what i was thinking too lol..this book was printed in like 1996 lol..thanx bro..btw what compiler do u suggest i use rather then dev ?

Dev-cpp is not a compiler.

I don't do Windows programming or C++ programming but I think that if you 've installed Dev-cpp then you have MinGW installed as well. MinGW is the Windows port of GCC, which is a popular C++ compiler. So I think if you can go to the MinGW directories you can use the command line tools.

type

code:

gcc input -o output

Them you can execute that. I think you can just type the filename in Windows in order to execute that.

And I think Dev-cpp should work fine for study pruposes. It at least lets you type in code and press "Compile & Run". That should be all you need.

Dev-C++ is an IDE, not a compiler. This IDE uses the GCC compiler. The problem with Dev-C++ isn't the compiler it uses, but the actual program (Integrated Development Environment). You should use the GCC compiler with command line tools and a simple editor.

The problem is that in my opinion Dev-C++ does a ghastly job of setting MinGW up, then hides that with a bunch of config options that are hidden from you.

Installing MinGW or Cygwin (or just Linux) is a much better course of action.

Of course, ultimately not using C++ as an intro language is the best advice I can offer.

ye so can i use anything in linux to learn c++?

also i just installg mingw and tried to compile test1.c this is what dos said

iostream : no such directory

syntax erros before ':' token

warning : no new line at the end of file

the code i wrote in there was

#include <iostream>

int main()
{
std::cout << "Hello World." << std::endl;

return 0;
}

Linux distros either come with GCC installed or you can easily install it with a package manager. And then you'd have a decent command-line. The prevalence of IDEs is largely the result of Windows being so common, and it having a terrible command-line interface.

And that program looks fine to me. I have no idea why you're getting those errors.

What prior programming experience do you have?

well lol..ive never really done any hardcore programing back in india they started teaching us some old school c++ like the code i posted earlier but then when i moved to canada it kinda got side tracked then i forgot how to use it..ive been doing turing for a few months now but i just wanted to try out c++ because my dad is a pro programmer but he used old c++ before for oracle corp..he was a programer there for 5 years and also a linux/unix server admin..he said if i want to learn programing i should learn c++ after turing or side by side so i just wanted to try it out

[wtd]

Well, I have to disagree with your father. He suggested C++ because it's what he knew. I know lots of languages, and I know that C++ always ends up getting in the way.

What do I suggest in its place? Probably at the top of the list would be Ruby or O'Caml.

ye my friend steve from school told me about it..ive never actually used it or even seen it just heard about it..oh well ill start with c++ on linux for now lol ..hey man btw u got msn or anything?..if u do add me at rocker_akshay@hotmail.com

You really should consider this carefully. You would genuinely benefit from something more expressive than C++.
