    Library of C++ opposed to C

    I am a C programmer. C programmer's use the stdio.h library for the basic I/O functions. I am working on C++. Learning it. I am very fluent with stdio.h. What is iostream.h like? Are the functions the same? I realize that instead of printf, you would use cout, cin, cerr and that sort. But is it still sscanf, scanf, sprintf, fprintf? Thanks.

    You can stick with the C I/O stuff if you want, a lot of people like how it is easier to change out to output the primitive stuff in different formats anyway.

    I am pretty sure there is a C++ counterpart for everything with C I/O. There are output string streams (write to strings rather than stdout or files), called ostrstream, instead of using sprintf. Likewise, there are input streams for reading from strings, istrstream, rather than sscanf. I don't know what fprintf is for, however, so I can't post a C++ equivlient.

    fprintf is writing to a file. You write the string to a file after you open it for writable access. So, if I wanted to use some C functions and C++ functions, then I would do:
    Code:
    #include <iostream.h>
    #include <stdio.h>
    ...
    I guess that's not too bad. Thanks.

    1st Guy/conio.h

    Like the first guy said, you can still use stdio.h, but you may also want to consider learning how to use conio.h as well. I find a lot more capabilities in it. Just a quick look at the header file will reveal a lot of things like the #define statements used to allow you to use color. Hope this helps.

    Strictly speaking, C++ is an extension of the C language. Therefore, as long as there are no incompatibilities between the functions being used, (think fgets and scanf!), then there should be no problems with mixing C function calls in a C++ program.

    The STL(Standard Template Library) is truly extensive. Literally hundreds of algorithms and numerous methodologies at your fingertips.
