How random function really works in C?

it should still fix some issue That's because rand is a pseudo-random number generator, which means it returns the same sequence for any given input (the input is by default 1).
You can seed the random number generator with the time to get a different value each time you run your program:
code :
#include <time.h>
#include <stdio.h>
#include <stdlib.h>

int main(void)
{
    struct timespec ts;

    timespec_get(&ts, TIME_UTC);

    srand(ts.tv_sec ^ ts.tv_nsec);

    int random_num = rand() % 100;
    printf("random number: %d", random_num);
}

hope this fix your issue Judging from your logcat and comments I can only conclude Your _c Object is null. You should look into your code and find the reason why, or post some relevant code so I can help you with that.

Array.sort random function does not works in iPhone's Safari

wish help you to fix your issue Here is my code:
code :
$scope.filtercolumn1=[];     
$scope.filtercolumn1.sort(function(a,b){
                    var nameA = a.toUpperCase(); // ignore upper and lowercase
                    var nameB = b.toUpperCase(); // ignore upper and lowercase
                    if (nameA < nameB) {
                    return -1;
                    }
                    if (nameA > nameB) {
                    return 1;
                    }

                    // names must be equal
                    return 0;
                })


this is done using angular + javascript  you can refer the logic from here 

Function logic works after random number of attempts

wish help you to fix your issue Here's an example where I make some assumptions about your code, but it's roughly how I'd expect things to work and a lot simpler.
You should be able to inspect Cart and find the matching item and remove it that way, if not then you should probably refactor how your cart is constructed.
code :
/**
 * Removes a 'product' from the cart
 *
 * @Route("/{id}/remove", name="product_remove")
 * @METHOD("GET")
 * @Template()
 */
public function removeAction(Request $request, $id) {

    $em = $this->getDoctrine()->getManager();
    $cart = $em->getRepository('ShopBundle:UserCart')->findOneBy(['user' => $this->getUser(), 'submitted' => false]);

    // Surely you must have some sort of cart->product or cart -> cartitem -> product relation here - I make some assumptions but what you
    // do should ideally work similar to this.

    foreach ($cart->getItems() as $item) {

        if ($item->getProduct()->getId() == $id) {

            $em->remove($item);
            $em->flush();
            $this->addFlash('notice', 'The product was removed!');
            return $this->redirectToRoute('product_showCart');
        }
    }

    // here you could put some kind of error because you failed to remove the product        
}

Function __base64Encode not works with Random Variable

this will help You could add Beanshell PreProcessor on your sampler and put something like:
code :
import java.util.Base64;    
import org.apache.commons.lang3.RandomStringUtils;

String sufix = "@jmeter.soi:Kazek2017@";
String address = Base64.getEncoder().encodeToString(new String(
                RandomStringUtils.random(10) + vars.get("timeStamp") + sufix).getBytes());

vars.put("encodedAddress", address);

Random loop works as planned but gets stuck on specific random number after a few calls

it fixes the issue Your code's main problem is that you are not preventing the same color from being selected multiple times. When you run it the first time, there is a high likelihood that at least one of your colors will be chosen twice. Think of it as simply selecting a number between one and ten at random. It is very difficult to randomly choose a different number ten times and never repeat.
Therefore, when you run your function again you have changed the backgroundColor property of each box, and some of them will have the same color, i.e. you do not have 13 different colors to choose from anymore. This means the second time your function runs you have fewer choices, and this continues and continues until you end up with only one or two possible colors to choose and every box ends up with the same color.
code :
var bloop = document.getElementsByClassName('specs');

for (var i = 0; i < bloop.length; i++) {
  bloop[i].onclick = function() {
    var colours = ['aqua','chartreuse','deeppink','dodgerblue','gold','indigo','lightpink','mediumpurple','coral','springgreen','red','peachpuff','deepskyblue'];
    for (var i = 0; i < bloop.length; i++) {
      var rando = Math.floor(Math.random()*colours.length)
      bloop[i].style.backgroundColor = colours[rando];
      colours.splice(rando, 1);
    }
  }
}
