Ok, WHOEVER reeds this and is looking to learn c++, i will give out the following header file names, and i want you to look on the net, for all the member functions it has, and explain them in a few short lines ie.

<iostream.h>

cout -
outputs text, used in a DOS program
cin -
inputs users text
cerr -
a function to display an error

etc etc.

here are some files. (i hope to keep going back to this and build up a library here, please dont post chit chat here, it will ruin the point of this thread, thanks)

string.h
stdio.h
stdlib.h
iomanip.h

string.h
The <string.h> header defines the following:
NULL
Null pointer constant.
size_t
As described in <stddef.h>.


stdio.h
The <stdio.h> header defines the following macro names as positive integral constant expressions:
BUFSIZ
Size of <stdio.h> buffers.
FILENAME_MAX
Maximum size in bytes of the longest filename string that the implementation guarantees can be opened.
FOPEN_MAX
Number of streams which the implementation guarantees can be open simultaneously. The value will be at least eight.
_IOFBF
Input/output fully buffered.
_IOLBF
Input/output line buffered.
_IONBF
Input/output unbuffered.
L_ctermid
Maximum size of character array to hold ctermid() output.
L_cuserid
Maximum size of character array to hold cuserid() output. (LEGACY)
L_tmpnam
Maximum size of character array to hold tmpnam() output.
SEEK_CUR
Seek relative to current position.
SEEK_END
Seek relative to end-of-file.
SEEK_SET
Seek relative to start-of-file.
TMP_MAX
Minimum number of unique filenames generated by tmpnam(). Maximum number of times an application can call tmpnam() reliably. The value of TMP_MAX will be at least 10,000.
The following macro name is defined as a negative integral constant expression:

EOF
End-of-file return value.
The following macro name is defined as a null pointer constant:

NULL
Null pointer.
The following macro name is defined as a string constant:

P_tmpdir
default directory prefix for tempnam().
The following macro names are defined as expressions of type pointer to FILE:

stderr
Standard error output stream.
stdin
Standard input stream.
stdout
Standard output stream.
The following data types are defined through typedef:

FILE
A structure containing information about a file.
fpos_t
Type containing all information needed to specify uniquely every position within a file.
va_list
As described in <stdarg.h>.
size_t
As described in <stddef.h>.


stdlib.h
The <stdlib.h> header defines the following macro names:
EXIT_FAILURE
Unsuccessful termination for exit(), evaluates to a non-zero value.
EXIT_SUCCESS
Successful termination for exit(), evaluates to 0.
NULL
Null pointer.
RAND_MAX
Maximum value returned by rand(), at least 32,767.
MB_CUR_MAX
Integer expression whose value is the maximum number of bytes in a character specified by the current locale.
The following data types are defined through typedef:

div_t
Structure type returned by div() function.
ldiv_t
Structure type returned by ldiv() function.
size_t
As described in <stddef.h>.
wchar_t
As described in <stddef.h>.
In addition, the following symbolic names and macros are defined as in <sys/wait.h>, for use in decoding the return value from system():


WNOHANG
WUNTRACED
WEXITSTATUS()
WIFEXITED()
WIFSIGNALED()
WIFSTOPPED()
WSTOPSIG()
WTERMSIG()


iomanip/h
This include file defines a set of manipulators that can affect to both input and output streams of the iostream hierarchy hierarchy of classes.
All these manipulators accept at least one parameter and mostly modify formatting information.
In order to be able to use these manipulators you have to explicitly include this file in your code.
