[SOLVED] C++ Error with sleep

Gugi · 2019-05-04 08:59:32

Hello, today i finally decide with which program language i will code.
After few hours i finally get my first ERROR, and i want you to help me find way out

So at first point, my code have to count from 15 to 0 and after this says " Hell Yeah"

and from point where is no ERRORS it looks like:

#include <iostream>
#include <unistd.h>
#include <cstdlib>

using namespace std;

int main()

        {

        for (int i=15; i>=0; i--)
    {


            cout << i <<endl;
    }
        cout<<"Hell Yeah!";

        return 0;
        }

But when i want add

sleep(1000);

        system("clear");

Program should count from 15 to 0 and says Hell Yeah, but here i found my FIRST ERROR

#include <iostream>
#include <unistd.h>
#include <cstdlib>

using namespace std;

int main()

        {

        for (int i=15; i>=0; i--)
    {
      sleep(1000);

        system("clear");

            cout << i <<endl;
    }
        cout<<"Hell Yeah!";

        return 0;
        }

In my Console it looks like:

Any ideas why?

I am using Code:Blocks IDE and GNU GCC compiler, as TUTORIAL says.

Read the Code of Conduct and only post thumbnails http://wiki.archlinux.org/index.php/Cod … s_and_code

And posting screenshots of code output is pointless.

Moving to NC

You tell your program to sleep for 1500 seconds (i.e. 25 minutes) before continuing. Have you waited for 25 minutes to see if it prints something?

Also, I recommend you try to format your code a bit more carefully (at least proper indentation of the code), to make things more readable (and spot mistakes more quickly).

That would imply that the shell can't find `clear`, which seems rather odd. Does it work if you run the command from your shell directly?

Then again, as a more general C/C++ programming advice, using the system() call is not very clean anyway.
If your tutorial is telling you to use system() (and tells you to use an IDE for learning to code right away), I would advise using a different tutorial (but then again, that's a personal opinion).

Also, as already mentioned above, please don't paste text output as images.

Ok, i will not upload text output as images.

Yes, in my shell 'clear' works, so i dont have any idea why it wont works in code

Did you recommend any tutorials with #EasierWay ?
