using system("xxxxx")

[T O]

Hi all,

I am very new to C programming and have come across problem.

My programme has opened and created a text document on the hard drive.
The document name is stored in a string called "output".

At the end of the program, I want to open the outputfile.txt
automatically using notepad.

So I figure what I want to do is

system("notepad .exe %s",output);

but of course it doesn't work.

Can anyone tell me if it is possible and if so how.

Can anyone tell me a good site that has full syntax for such command. I
have C Primer plus etc, and other books but they all lack info on such
commands.

Thanks very much in anticipation

A good one, though.
and snprintf and sprintf don't appear to be in any of the libraries with
it (unless someone can tell me different).

Can Dev C++ be told to act as a C compiler, or is it just a C++
compiler?

Yes; in fact, I only use it as a compiler (or rather compiler
environment; Dev-C++ itself is a shell around gcc + MingW or Cygwin) for
two languages, one of which is C and the other of which is not C++.

<snip> sprintf() is a standard C function (and C++ incorporates the C
library). Try "#include <string.h>". <OT>If you're stuck using it as
a C++ compiler, try "#include <cstring>" (I think).</OT>

sprintf is in <stdio.h>. (Standard) C++ supports the C headers as both
<xxx.h> which puts (leaves) the names in the global namespace, and
<cxxx> which puts functions in std. It is the _C++_ headers where the
standard has only e.g. <iostream> in std not the prestandard
common-use <iostream.h> in global.
