Thread: Dos programming Concept problem.

I was usually programming in windows before.

now i recognized a difference between win and dos programming:

in win, like VB , FLASH, etc. it can run muti - program at a time,
like playing the music, playing movie , and calculation at the same time.

dos program , usually it has only one "main loop" ,
the program is running the "loop" continuously .

what is the way to run muti - program?

you obviously don't understand windows programming very well either. Windows programming has one main loop controlling everything just as a DOS app does. The main difference is that a windows program works with windows to accomplish tasks, a dos app does everything on it's own.

there is no way to multi-task in dos if that's what you're asking.

>>>you obviously don't understand windows programming very well .

yes, since i only write VB and FLASH before.


Like VB or VC++ , it has "timer",
we can run many timers at the same time.
i know that every program is a MAIN LOOP looping.

is it means that i must write progman like this :

// a muti - timer's progman
void main(){
if ( time to invoke the timer function ) ......;
if ( time to invoke the timer function ) ......;
if ( time to invoke the timer function ) ......;
..
..
..
}

is it like this ?


and if the "PLAYMUSIC()" function in a game is running,
but how can control the sprite ??

that means that i must write :

int i
void main(){
playmusic( the i'th note );
control (....);
....
....
i++;
}

like this form????

what you're asking about has nothing to do with windows or dos programming, it's simply a matter of it being in c/c++.
You can write a program with several if statements or anything else you want, just as in windows. Here's an example program in DOS.

Code:

#include <iostream>
using namespace std;
//NEVER USE VOID MAIN, EVER!!
int main()
{
     for (int i=0;i<=5;i++)
     {
        std::cout<<"hello"<<std::endl;
      }
return 0;
}

this is only a process.
no program will run once like this.

it must in looping to check the mouse, key ....

first you ask a question, then you smart off to those who (know more than you) and help you.
That program will run just fine, i don't have to check for the mouse or keys. Besides all i'd have to do is do cin>> whenever i want input from the keys.
What you said is like saying hello world doesn't work, does that check for keys?? NO.
>>no program will run once like this.
Jesus man, why don't you try compiliing it?

OK.

dude its quite simple they dont run at the same time they switch turns so quickly it seems theyre doing their **** at the same time. ie if you had 2 timers...

timer 1 will increment 1
timer 2 will increment 1
timer 1 will increment 1
timer 2 will increment 1
timer 1 will increment 1
timer 2 will increment 1
timer 1 will increment 1
timer 2 will increment 1

until it reaches wutever number

O., SEE.
thx.
