I checked the c++ reference website: http://www.cplusplus.com/reference/ I cannot see many of the header files i knew and used, like the "iostream.h", or "conio.h". Why is that? Are they replaced with new? If that's true. what more 'old' header files are replaced? Can i see somewhere this "progress", so to stay up to speed? And when i write code that include the iostream.h for example it is running flawlessly. Is this for backwards compatibility? Shouldn't i have to see a compiler warning?
EDIT: To make some clarifications, the .h standard has been deprecated in C++.
Also, do not use
<iostream.h>
Since the 98 standard it has also been deprecated, the header iostream.h is a non-standard header and does not exist on all platforms. Code that uses it should be considered non-standard legacy code and is not portable.
You shoud use <iostream> instead.
Finally, conio.h is a C header file used mostly by MS-DOS compilers to provide console input/output. It is not part of the C standard library or ISO C, nor is it defined by POSIX.
This means, avoid using this too, if you are on a system which supports it.
