hi

i am using g++ to compile my stuff and i get an error when i try to comile my hello world

here is the code:

#include<iostream.h>
main()
{
cout << "Hello World";
cin.ignore();
return 0;
}

then i did :

bash-2.05b$ g++ -o bla test1.cpp

then i get the error:


from test1.cpp:1:
/usr/include/c++/3.2.3/backward/backward_warning.h:32:2: warning: #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the <X> header for the <X.h> header for C++ includes, or <sstream> instead of the deprecated header <strstream.h>. To disable this warning use -Wno-deprecated.

hrm what am i doing wrong?

thanks guys

oh woops forgot the int before main heh heh

lets see if that works.....

hrmm i still get the same error

any suggestions?
thanks

this works too.

#include<stdio.h>

int main(int argv, char argc)
{
printf("Hello World");
return 0;
}

That's a C program.

Lyle

oh yay!!

i figured it out baby!

#include <iostream>
#include <string>
using namespace std;

i guess g++ doesnt like the old header formats....

Lyle, it compiles in g++ good enough.

True, but I'm working under the assumption that Longinus was trying to write a C++ program since the iostream header was used.

Lyle

aaaaaahhh ok.
never realy liked iostream.h
dont know why.

is there an <iostream.h> for C? I don't think so. I thought it came along riding the C++ classes/templates wave. I prefer print() in theory, but in practicality, I use fstream and iostream a whole bunch. Maybe that's just because I learnt C++ first.

i learned c++ first but used print instead.

oh so you can use the print() funcion in c++?!?

worked for me , try it.....
