C++ Tutorial

Hi,

I am trying to learn C++. But I cannot seem to get the most basic program compiled.

I say #include < stdio.h >

and it says it cannot find it when compiled with gcc or cc.

if I do whereis stdio.h
it says
/usr/include/stdio.h

if I put the full path in the include statement, I get the same error. Someone please help.

it should be:

Code:

#include &lt;stdio.h&gt;

though if you're trying to do c++, it should just be <stdio>.

The full path will never work with <>, you'd want to just use "".

If it still doesn't compile, you might have to specify -I/usr/include, though you shouldn't have to.

Are you SURE that it will like the html tags instead of
the < and > ?

You seem to be using C header files instead of C++. In C++ a simple hello world app would be similar to the one below.

#include <iostream>
using namespace std;
int main (void)
{
cout << "Hello, World!\n";

return 0;
}

Use #include <cstdio> instead of #include <stdio.h>
If I'm right, stdio is deprecated.
