    Exclamation I have a few questions about c headers

    Dear Forum Users,

    Kindly be informed that I use #include<stdio.h> and #include<conio.h> are these correct? should I use them both in my program? In this cprogramming website I watch that they use #include<iostream> which should I use?

    I use borelandc++ and sometimes turboc with blue screen/

    kindly guide me.

    With regards,
    Soumya

    #include <stdio.h>
    This is the standard include file for conducting basic input/output within a C program.

    conio.h is an obsolete header file, used by obsolete compilers for obsolete operating systems.

    #include <iostream>
    This is the standard include file for conducting basic input/output within a C++ program.
    Note that this used to be called <iostream.h> before the C++ language was standardised. If your compiler doesn't support <iostream>, it is obsolete.

    I don't know how up to date your version of borelandc++ is, but you should definitely stop using your dos-like blue-screen turboc (it's obsolete).
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Hi Salem, thanks for your answer. In many engineering colleges in India still prefers turboc blue screen to to teach cprogramming. Do cprogrammers always use borlandc++ and code blocks? Should I always use <iosream> as my header file?

    Ask your tutor how learning 25+ year old technology prepares you for a career in the 21st century.

    Thanks Salem, What compiler you use to write programs in C?

    At the moment, I'm using GCC as the compiler suite and code::blocks as the IDE
