Re: Press any key to continue...

[Nickolaus]

There's a much easier way to do this:

#include <fcntl.h>

system( "pause" ); //does exactly what you want

Ok gentlemen, thank you for your help. But I still can't get the result I
was hoping for. So here's very simple code I wrote. Please tell me what's
wrong with this.



#include <iostream.h>
#include<conio.h>

//function prototypes
void press_any_key();
void one();
void two();
void three();

void main()
{
press_any_key();
one();
press_any_key();
two();
press_any_key();
three();
}

void press_any_key()
{
char any_key;

cout << "\n";
cout << "Press any key to continue.";
any_key = getch();
cout << "\n\n";
}

void one() {cout << "One\n";}
void two() {cout << "Two\n";}
void three() {cout << "Three\n";}

Your program basically works as is aside from the void main().. here's some
decent code, more C++:

#include <iostream>
using namespace std;

// function prototypes
void press_any_key();
void one();
void two();
void three();

int main()
{
press_any_key();
one();
press_any_key();
two();
press_any_key();
three();
return 0;
}

void press_any_key()
{
char ch;

cout << "\nPress any key to continue.";
cin.get(ch);
cout << "\n\n";
cin.clear();
}

void one() {cout << "One\n";}
void two() {cout << "Two\n";}
void three() {cout << "Three\n";}

Hope this helps

[John]

Thank you for your help. I was able to get the same result by doing this:


#include <iostream.h>

//function prototypes
void press_any_key();
void one();
void two();
void three();

void main()
{
press_any_key();
one();
press_any_key();
two();
press_any_key();
three();
}

void press_any_key()
{
char any_key;

cout << "\n";
cout << "Press any key to continue.";
cin.get(any_key);
cout << "\n\n";
}

void one() {cout << "One\n";}
void two() {cout << "Two\n";}
void three() {cout << "Three\n\n\n\n";}


but still, only the 'Enter' key will make it proceed. Any other keys such
as abcd... or spacebar won't make it proceed to the next step.
Any suggestions?

About the only function that I know is getch() found in conio.h, but conio.h
is not available in all platforms.

Someone already suggested
system("pause");

But I don't remember if this works in Unix/Linux. It should work in all
DOS apps though...

Maybe someone knows a more portable way...

[John]

I've tried system("pause"); but kept getting compiler error. Do you think
maybe this has got something to do with my Windows 2000?

Did you use #include <fcntl.h> in the header?

[John]

Yes, I did. Uhh can you say "Duh?"

Well, the cin.get() & the getch() are getting the first character you
type, but they are buffered, so they wait until you've typed in entire line
before preceding. For example:

char a = getch();
char b = getch();
char c = getch();
char nl = getch();

if run, the program will stop for input at the first getch(). If you
were to type "abc" and then Enter, it would not stop again, and a would =
'a', b == 'b', c=='c' and nl == '\n'.

Maybe you can try a
cin.ignore(256,'\n');
cin.get(); //Or getch();
if you're using C++.

I had problems with reading string or something like that and I had to empty
the buffer with cin.ignore and I think I used it for a thing like you want
to do but it's a long time ago so maybe this does not have any sense :) I
don't have C++ compiler so I can't try it..
