I have FC3 all 4 discs !!
I am pasting the correct version of both the programs.
#include<iostream.h>
int main()
{
cout<<"Hello, World";
return(0);
}
Ok, when i compile the above program u should get a warning which is as
below this is concerned with the section 17.4.1.2 so you can refer what
that section says but it's no use
You can just simply ignore it !!
[EMAIL PROTECTED] ~]$ vi 1.cpp
[EMAIL PROTECTED] ~]$ g++ -o 1 1.cpp
In file included from /usr/lib/gcc/i386-redhat-
linux/3.4.2/../../../../include/c++/3.4.2/backward/iostream.h:31,
from 1.cpp:1:
/usr/lib/gcc/i386-redhat-linux/3.4.2/../../../../include/c+
+/3.4.2/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 <iostream> instead of the deprecated header
<iostream.h>.
To disable this warning use -Wno-deprecated.
so i will write the compilation once again
[EMAIL PROTECTED] ~]$ vi 1.cpp
[EMAIL PROTECTED] ~]$ g++ -o 1 1.cpp -Wno-deprecated
Now you want get an error and your program will run satisfactorily
[EMAIL PROTECTED] ~]$./1
Now the Problem with namespaces here goes
#include<iostream>
using namespace std; // I am using namespace so i can
// remove .h
int main()
{
cout<<"Hello, World";
return(0);
}
[EMAIL PROTECTED] ~]$ vi 1.cpp
[EMAIL PROTECTED] ~]$ g++ -o 1 1.cpp
[EMAIL PROTECTED] ~]$ ./1
Hello, [EMAIL PROTECTED] ~]$
I hope this solves your query !
I have tried to explain the best that i can
if you have any more queries you can mail me offlist too
