sound(x)

[curlyj]

Hi!
Im new to C++ and have been reading through C For Dummies Volume 1

I am using Borland C++ 5.5.1
the book states that although it is written for C the book works for C++ as well.

in the book there is the following example that is to be typed in, yet it will not work. Could anyone help?
Thanx!

The code...............


#include<stdio.h>
#include<conio.h>
#include <dos.h>

void dropbomb(void);

void main()
{
printf(&quot;Press any key to drop bomb:&quot;
getch();
dropbomb();
printf(&quot;\nYikes!\n&quot;
}

void dropbomb()
{
int x;

for (x=880;x>440;x-=10)
{
sound(x);
delay(100);
}
nosound();
}
QBasic is fun! Go see what I've done!

sound() is neither a C or C++ function or keyword.
Your example probably is older DOS code written for a compiler that supported this compiler specific function call. You are most likely compiling Win32 console programs with Borland C++ 5.5.1 which are only simular to DOS programs in looks. You can use,
Beep(
DWORD dwFreq, // sound frequency, in hertz
DWORD dwDuration // sound duration, in milliseconds
);
under Windows NT. Under Win95, the parameters are ignored and windows plays the default sound.


Also, use int main() instead of void main() and use return 0; at the end of main.
