Pauseing a program for 3 seconds

Hello, I am new to C++, this is only my third post on this forum.

Also, does anyone know how to make a program pause for 3 seconds, and then continue on like normal?
The only way I know of doing it is by using the

Code:

---

system("cls");

---

command. And I want to avoid the system command all togeather.

Thanks in Advance, August

P.S. My compiler doesn't have <windows.h>

Nice page from the faq :D

Try this

Code:

---


for(long i= 0; i<100000000000000; i++);

---

Put this where u want to pause the thing.

This makes 100,000,000,000,000 iterations where "i" goes from 0 to that really huge number. Since there is no body for the loop, the loop does nothing for that many times. Try experimenting with the really big number. Make it more, or make it less to suit ur needs.

if u want to pause for exactly 3 sec, I recommend using the time.h library mentioned by the previous poster instead of the above.

But if u just wanna pause for some time, then do my way.

I hate to break it to you sridar, but that loop really is not a suitable option for pausing.

I tried it MadCow257 and it worked for me.
I used BloodShed Dev compiler to make a program in which the text runs from the left to right of the screen in 1 second intervals

Ex:

"Hello World"
"Hello World"
"Hello World"
"Hello World"
"Hello World"
"Hello World"
"Hello World"
"Hello World"
.......



The code i mentioned b4 printed to the screen, the i used gotoxy() and clrscr() to make it so that the text is "moving" Every second it refreshed for me.

Here is the code:

Code:

/*
  Name: Scroller
  Copyright: 2005

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

using namespace std;
//*****************************************************************************
void Scroll(string &msg)
{
      string scrolled,temp,temp2;
     
      temp=msg.substr(1,(msg.length()));
      temp2=msg.substr(0,1);
     
      msg=temp+temp2;
      if(msg.length()+1==' ')
      {
                            cout<<temp+' '+temp2;
                            }
      else
      {
     
      cout<<msg;
      }
      }
//*****************************************************************************     
int main()
{
    string msg;
    cout<<"Enter the message that you wish to display as scroller: ";
    getline(cin,msg);
    msg=msg+".      ";
    int x=0;
   
    while(x<100000)
    {
              Scroll(msg);
              for(long y=0; y<30000000; y++);
              system("cls");
             
              x++;   
              }
    cin.get();
    return 0;
}

I know it works, but I was just saying that there are better ways. You might want to read the FAQ for some examples.

I was just mentioning an easier way to do it. I honestly believe that the faqs are the way to go, but they often require u to write more code.

The op can choose whichever he wishes.

>I was just mentioning an easier way to do it.
Easier, perhaps. But far from optimal. Busy wait loops are generally considered anti-social, and using a loop with an arbitrary value is silly because the loop will have different times for just about every different processor it's run with. A better solution is with the <ctime> functions and types, but that still doesn't help the fact that it's still a busy wait loop. Sadly, there's no good portable solution, so it's better to go with a system-dependent solution that actually does the job right.

>for(long i= 0; i<100000000000000; i++);
This is undefined behavior unless long on your system can support values that large. On my system, long is 32 bits, and signed integral overflow is undefined if I'm to believe the C++ standard.

ok. you guy's make everything complicated.

the easiest way is this. (if you want it PAUSED for 3 seconds)

Code:

---

//headers
#include <windows.h>

//code
Sleep(3000); // in milliseconds

---

make sure you use capital S on sleep

>#include <windows.h>
Nice try slick, but the OP explicitly said "P.S. My compiler doesn't have <windows.h>".

oh crap

darn, and i was feeling pretty smart for a sec

theres a wait(); function im pretty sure, i think in either devcpp or borland's <conio>. but i haven't used that in a long time

If he doesn't have <windows.h>, he probably is not going to have conio either.

What, is wait(); a windows.h function as well?

well you know what would be an easier solution... getting a new compiler?

hey cool-august, what compiler are you using?

instead of getting a new compiler wouldnt downloading windows.h and conio.h be the easier solution?

>wouldnt downloading windows.h and conio.h be the easier solution?
Yes, if you ignore the fact that headers only contain declarations, and even if you also downloaded the corresponding libraries, the chances of them being compatible with your compiler are practically zero, it would be easier.
