Beep-Beep

:confused:

Hey does anyone know how to set up this program with a command line that will have: prog sound1 duration1 sound2 duration2....


#include <iostream.h>
#include <stdlib.h>
#include <windows.h>

void soundSequence(int sounds[], int duration [], int numSounds);
int main(int argc, char *argv[])
{
Beep(1000,1000);//1kHz tone for 1 second
Sleep(1000);//Wait for 1 second!!
Beep (2000,1000);//2kHz tone for 1 seconds
Beep (4000,2000);//4kHz tone for 2 seconds
Beep (6000,4000);//6 kHz tone for 4 seconds
system("PAUSE");
return 0;
}


Thanks for your help in advance.

Have a read of this

The beep() function is platform dependent.

As I recall... With Win98, the frequency and duration will be ignored. You'll get a default beep. With WinXP, the frequency and duration are used only if you don't have a sound card. If you have a sound card, you get the "Windows Default" sound.

Code:

---

#include <iostream.h>
#include <stdlib.h>
#include <windows.h>

void soundSequence(int sounds[], int duration [], int numSounds);
int main(int argc, char *argv[])
{
  //Convert the following code into a function with prototype:
  //void soundSequence(int sounds[], int duration [], int numSounds);
  //main is to read command line arguments and load up arrays to
  //pass to function.  Allocate memory dynamically for arrays.
  //command line: prog sound1 duration1 sound2 duration2.....
  //sound of 0 will sleep for the duration.
 
  Beep(1000,1000);//1kHz tone for 1 second
  Sleep(1000);//Wait for 1 second!!
  Beep (2000,1000);//2kHz tone for 1 seconds
  Beep (4000,2000);//4kHz tone for 2 seconds
  Beep (6000,4000);//6 kHz tone for 4 seconds
  system("PAUSE");       
  return 0;
}

I hope this is better;)

just to point out...

You can't just compare the command line arguments with just the assignment operator

you must use and should I think, use a function like 'strncmp'

ex:
/* check the first argument */
if ( (strncmp(argv[1],"-c",2))==0 )
{
/* do something */
}
else {
printf("Bad command line argument");
}

hope this helps

int main (int argc, char **argv)
{
int numpts = argc - 3;
double *data = new double[numpts];
for (int i = 0; i < numpts; i++)
data[i] = atof (argv[i+3]);
if (strcmp (argc[1], "mav")
{
int winsize = atoi (argv[2]);
}
return 0;
}


Hope this helps some :p
