<Help> Simple Pause Needed.

[da Vinci]

OK, this has got to be a simple one and yet I cannot find the answer
in my textbook.

How can I get a simple pause after an output line, that simply waits
for any key to be pressed to move on?

Basically: "Press any key to continue..."

I beleive that I am looking for is something along the lines of a....

cin.get

but do not know the exact syntax for it.

I know it is so simple.... I can make and call functions with eyes
closed yet this illudes me...

Thanks.

You can get almost that. With most systems with keyboards,
input is 'line buffered', so your program doesn't see any
input until the user presses the 'Enter' (aka 'return') key.
This lets one edit the input before submitting it to the
program. Think 'fumble-fingers', and 'backspace key' :-)

So for such systems, you can have a 'Press Enter to continue',
in a few different ways.

You could use cin.get(), but I'd only use that as a prelude
to the program's termination, since even though 'get()' only
extracts a single character, the user could easily type in
e.g. ten characters (or more), and those characters would
still be waiting in a 'buffer', and be presented to the
next input request. So you'd need extra code to discard them.
(cin.ignore() etc.)

I find the most useful general purpose way to do this is
with the (nonmember) 'std::getline() ' function, which will
extract all characters up to the first newline character, and
store them in a std::string object. (The newline character itself
is extracted but not stored). Then just throw the string away,
or give it to your cat. :-)

Example:

#include <iostream>
#include <string>

void wait4user()
{
std::string response;
std::cout << "Press Enter to continue";
std::getline(st d::cin, response);
}

int main()
{
std::cout << "Hello";
wait4user();
std::cout << "world\n";
wait4user();
return 0;
}

cin.get() would work, but has the disadvantage I cited above.

That's what books are for. :-) Any good C++ compiler
will also provide documentation for the standard library.

Open your eyes. :-)

Re: &lt;Help&gt; Simple Pause Needed.

Excellent!

It worked like a charm.

I didnt know that info about the cin.get and having characters in the
buffer. Appreciate that! I bet that will save a great deal of heart
ache in the future.

Aw, come on.... keeping your eyes open during the ride is no fun!! :-)

Thanks again.

There is no way in standard C++ (which is the topic of this newsgroup)
to do something like that. The closest thing would be

std::string dummy;
std::cin >> dummy;

which will wait for <enter>. If you want to detect a key without <enter>,
you will have to use something from your implementation. For further
informations, please ask in a newsgroup supporting your compiler.

Warning:

This might be sufficient for some circumstances, but
note that there could be a problem.

If this construct is used in a place before subsequent
input is requested, and if in response to the above,
the user supplies input with embedded whitespace,
e.g. "OK I did", only the "OK" will be extracted,
and "I did" is still there waiting, and will be supplied
to the next input.
Use std::getline() instead.

Start reading, my friend. :-)

Perhaps I was not clear enough, but note that my
remarks about 'buffer' were only a generalization
about 'most systems' you're likely to encounter.

From the program's perspective, this issue is not
limited to just cin.get() but to all input operations.
The reason what I showed works, is that by definition,
std::getline() reads everything on a whole line,
and most systems with keyboards will buffer a line
at a time.

The language itself knows nothing about such operating
system buffers, and only 'sees' one character at a time
(The OS controls and supplies these characters to your
program).

Just in case you wanted to see how I used it, this is the program I

From the alt.comp.lang.l earn.c-c++ FAQ
(http://www.faqs.org/faqs/C-faq/learn/):

13: What should I look for when picking a book to learn from?

[...]
Many C and C++ experts recommend against using ANY book written by
a certain Herbert Schildt. To see why, read the answer to question
16. [...]

16: Why do many experts not think very highly of Herbert Schildt's
books?

A good answer to this question could fill a book by itself. While
no book is perfect, Schildt's books, in the opinion of many
gurus, seem to positively aim to mislead learners and encourage
bad habits. Schildt's beautifully clear writing style only makes
things worse by causing many "satisfied" learners to recommend his
books to other learners.

Do take a look at the following scathing articles before deciding
to buy a Schildt text.

http://www.lysator.liu.se/c/schildt.html

http://herd.plethora.net/~seebs/c/c_tcr.html

The above reviews are admittedly based on two of Schildt's older
books. However, the language they describe has not changed in the
intervening period, and several books written at around the same
time remain highly regarded.

The following humorous post also illustrates the general feeling
towards Schildt and his books.

http://www.qnx.com/~glen/deadbeef/2764.html

There is exactly one and ONLY one C book bearing Schildt's name on
its cover that is at all recommended by many C experts - see Q 25.

Don't! This code is very hard to read. Do not use tabs since some
newsreaders (as mine) remove them, but at least indent by one or
two spaces.
[color=blue]

I hope so, if not, don't tell us your name :)

The program in general is quite cool. A couple of guidelines though :

1) give better names to your variables and functions
2) try to break your code a bit more; a function must have a
representative name. If the name is too general (such as do_this() ),
break it until its name represents exactly what it does.
3) too much comment is like not enough
4) learn about arrays and vectors
5) don't give up!

<personal opinion>
take the habit of naming the variables even on declaration,

Nope. main() has two allowed forms :

int main()

or

int main(int argc, char **argv)

where the names are optional.

take the habit of defining one variable per line and
to comment each of them. "various program functions" is not
very clear imo :)

Display_Main_Me nu has a misleading name. It does not
only display, it asks for an option and returns it. Either
rename your function or (preferrably) break it in two.

non portable, be careful. A system without 'cls' will do
nothing. On my system, 'cls' from the command prompt formats
the disk without warning. its a good thing I did not run it :)

a variable named good_or_bad does not inform on its use..

This kind of comment is useless and only clutters the code.

mmm.. what about an array or a std::vector here (or even a std::map)?
If you didn't learn about them, that's ok, but know that it would
be a lot simpler.

Make the previous case in a seperate function.

Every case should look like these 3 : calling a function or two,
but that's it. If not, well.. it makes it harder to understand.

When something can have two values meaning 'ok' or 'bad', use a bool
which can have the values 'true' or 'false' :

bool b = true;
b = false;

indicate intentional fall-through with a comment since in some cases,
it may not be clear if it is or not.

What about something like

return (prodnum >= 1) && (prodnum <= 5);

assuming the function returns a bool.

Mmm.. I though \n was not portable, I should have informed myself.
Let me rephrase.

I prefer using std::endl since it is clearer than a bunch of \n.
It is also supposed to flush the buffer, but flushing the buffer
does not necessrily mean that the data is written.

What's the "approved" method of marking the text you're responding to when
the corporate-mandated, braindead reader (initials are LN) doesn't do it for
you. I've been using <previous></previous> but that seem hokey.
