问题
How can I get a version of language C/C++(downloaded??) where the functions sound, nosound, delay are present in the library DOS.H? For example it doesn't exist in the version c/c++ on code::blocks. What have I to do in order to use/find the functions sound/nosound/delay? thank you for your help !
回答1:
In Windows programs you may use win32 functions:
- Sleep() as a replacement for
delay() - Beep() as a replacement for a combination of
sound()+delay()+nosound().
回答2:
download (sigh) a copy of TurboC/TurboC++.

if u r having above win 7,, Download borland Turbo c++ using dos box to listen to a beep for 500 miliseconds, use the following code,
#include<iostream.h>
#include<conio.h>
#include<dos.h>
void main()
{clrscr(); //for clearing the screen...
int x;
x=1000; // here 1000 is the frequency of the sound
sound(x); //u can directly write integer in the place of x
delay(500);
nosound(); //it is necessary to close the sound or u will keep on hearing
getch(); // to wait at the end of program
}
