Créez une barre de chargement de style Windows en suivant les instructions suivantes.

^{(remarquez que cela diffère de Loading ... Forever )}

Votre sortie devrait commencer par [.... ].

Chaque tick, vous devriez attendre 100 ms, puis déplacez chaque point d'un caractère à droite. si le point est sur le dixième caractère, déplacez-le vers le premier. Notez que vous devez effacer l’écran avant de relancer la sortie. La sortie est ordonnée comme suit:

[....      ]
[ ....     ]
[  ....    ]
[   ....   ]
[    ....  ]
[     .... ]
[      ....]
[.      ...]
[..      ..]
[...      .]

..Alors il boucle pour toujours.

Règles

• C’est du code-golf , donc la réponse la plus courte gagne ^{je doute d’accepter une réponse gagnante}
• S'il vous plaît fournir un fichier gif de la barre de chargement en action si possible.

f(i){usleep(dprintf(2,"\r[%-10.10s]","....      ...."+i%10)<<13);f(i+9);}

Or, if your system's stdout doesn't need to be flushed after every write without a newline:

C (gcc), 70 bytes

f(i){usleep(printf("\r[%-10.10s]","....      ...."+i%10)<<13);f(i+9);}

How it works

• usleep( sleeps for the next return value in microseconds.
• dprintf(2, prints to file descriptor 2, or stderr. This is necessary because while stdout is line-buffered (meaning output will not show until it prints a newline), stderr is character-buffered (all output is shown immediately).
• "\r prints a carriage return (clears the current line).
• [%-10.10s]" is the printf format specifier for a string with exact length 10 (no matter what string provided the output will always be a string with length 10), padded with spaces to the right if necessary. This will be enclosed with brackets.
• ".... ...." is the loading bar.
• +i%10 offsets the loading bar by the current index modulo 10. For example, if i == 3, i % 10 is equal to 3. Offsetting the loading bar by 3 makes it equal to ". ....".
• When the offset-ed string is passed to the printf format specifier, it limits to a length of 10 if necessary and adds spaces to the end if necessary. Therefore, the loading bar will always be between [.... ] and [. ...].

String s="....      ";void c()throws Exception{System.out.print("["+s+"]\r");s=(s+s).substring(9,19);Thread.sleep(100);c();}

• Mentioning of \r thanks to @Phoenix.

The carriage return \r resets the 'cursor' back to the begin of the line, which can then be overwritten. Unfortunately, online compilers nor the Eclipse IDE doesn't support this, so I've added a gif at the end of this answer to show it from Windows Command Prompt.

Try it here. (Slightly modified so you won't have to wait for the time-out before viewing the result. Also, the TIO doesn't support carriage returns, so every line is printed without overwriting the previous line.)

Explanation:

String s="....      ";            // Starting String "....      " on class level
void c()                          // Method without parameter nor return-type
 throws Exception{                // throws-clause/try-catch is mandatory for Thread.sleep
  System.out.print("["+s+"]\r");  //  Print the String between square-brackets,
                                  //  and reset the 'cursor' to the start of the line
  s=(s+s).substring(9,19);        //  Set `s` to the next String in line
  Thread.sleep(100);              //  Wait 100 ms
  c();                            //  Recursive call to same method
}                                 // End of method

VBA 32-bit, _{159 157 143 141} 134 Bytes

VBA does not have a built in function that allows for waiting for time periods less than one second so we must declare a function from kernel32.dll

32 Bit Declare Statement (41 Bytes)

Declare Sub Sleep Lib"kernel32"(ByVal M&)

64 Bit Declare Statement (49 Bytes)

Declare PtrSafe Sub Sleep Lib"kernel32"(ByVal M&)

Additionally, we must include a DoEvents flag to avoid the infinite loop from making Excel appear as non-responsive. The final function is then a subroutine which takes no input and outputs to the VBE immediate window.

Immediate Window function, 93 Bytes

Anonymous VBE immediate window function that takes no input and outputs to the range A1 on the ActiveSheet

        DoEvents
        Sleep 100
        i = (i + 1) Mod 10
    Loop

-2 Bytes for removing whitespace

The gif below uses the full subroutine version because I was too lazy to rerecord this with the immediate window function.

Batch, 99 98 bytes

Saved 1 byte thanks to SteveFest!

(I could remove \r from the code, but in the spirit of batch golfing, I won't.)

:g
@CLS
@ECHO [%s%]
@SET s=%s:~-1%%s:~,-1%
@ping 0 -n 1 -w 100>nul
@GOTO g

There are four spaces after the first line.

The main logic is modifying the string. %s:~-1% is the last character of %s% and %s:~0,-1% is all but the last character of %s%. Thus, we are moving the last character to the front of the string, which rotates the string.

main=mapM id[do system"cls";putStrLn('[':["....      "!!mod(i-n)10|i<-[0..9]]++"]");threadDelay(10^5)|n<-[0..]]

Explanation

mapM id             sequentially perform each IO action in the following list
[                   start a list comprehension where each element is...
  do                  an IO operation where
    system "cls";       we clear the screen by calling the windows builtin "cls"
    putStrLn(           then display the string...
      '[':                with '[' appended to
      [                   a list comprehension where each character is...
        "....      "!!       the character in literal string "....      " at the index
        mod(i-n)10          (i - n) % 10
      |i<-[0..9]]         where i goes from 0 to 9
      ++"]"             and that ends with ']'
    );
    threadDelay(10^5)   then sleep for 100,000 microseconds (100 ms)
|n<-[0..]]          where n starts at 0 and increments without bound

Haskell's purity made generating the cycling dot pattern somewhat complex. I ended up creating a nested list comprehension that generated an infinite list of strings in the order they should be output, then went back added the appropriate IO operations.

Ruby, 61 bytes

If the spec were for the dots to scroll left instead of right, it would save 1 byte because rotate! with no arguments shifts the array once to the left.
