can't include iostream.h

[MaaSTaaR]

Hello ...

i am using Ubuntu Linux , i tried to use GCC to compile some C/C++ codes ,
but the first problem showed for me is "t.c:1:22: error: iostream.h: No such
file or directory" and when i do g++ test1.c it's show for me this problem

In file included from /usr/include/c++/4.0.2/backward/iostream.h:31,
from t.c:1:
/usr/include/c++/4.0.2/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.

Hi MaaSTaaR,

You should fix your code to use the C++ header: #include <iostream>

The C++ standard has been out for almost a decade now.

Hi MaaSTaaR,

Try this code:

#include <iostream>
int main()
{
std::cout << "Hello World" << std::endl;
}

The compiler will create an executable. Are you running the
executable? By default, I believe, it is called a.out Or you can
give it a name like:

gcc -o foo foo.c

where foo.c is your source file name and foo is the name of the
executable.

Then execute foo with:

./foo

Iostream is a C++ header, not a C header and in all the newer version of
GCC, it's just iostream, not iostream.h. Try this

#include <iostream>

int
main(int argc, char *argv)
{
std::cout << "Hello World" << std::endl;
return(0);
}

g++ test.c -o test
./test

:b!

Those of you who think you know it all,
