 or not. User cache means you cache data(save data) into APC. Now this could be an object, variable anything. 
Lets say you get user profile from database, and you want to cache it so the next requests wont be needing to fetch from db. You would cache it in APC after the first fetch from db.  this is an example of where you might use APC user cache
         $userObject->name = "Mike";
         $userObject-> age = 12;
         apc_store("user", $userObject);

You can retrieve the value, with the key which is user.
        var_dump(apc_fetch("user"));

 Q:

C++, How do i write cout output side by side?

As mentioned in the title, I do not know how to format my std::cout output such that the inner for-loop writes in "rows" but the outer for-loop produces columns.
My Code:
#include <iostream>
#include <iomanip>
using namespace std;

class LoopTest
{   //Access specifier
    public:
        //Data Members
        int outer_size = 2;
        int inner_size = 3;

    //Memberfunction
    int testing()
    {
    freopen("/home/user/training/exercise/e0/TESTPROGRAM_OUTPUT.dat", "w", stdout); //redirect output to file

        for(int i = 0; i <= outer_size; i++)
        {   
            cout <<  " number: " << i;
            for(int j = 0; j <= inner_size; j++)
            {
                cout << " j*(j*i): " << j*(j*i); 
                cout << "  ";
                cout << "\n";
            }

        }
        fclose(stdout);
        return 0;

    }
};

The code shown above produces the following output:
     number: 0 j*(j*i): 0  
 j*(j*i): 0  
 j*(j*i): 0  
 j*(j*i): 0  
 number: 1 j*(j*i): 0  
 j*(j*
or not. User cache means you cache data(save data) into APC. nowadays this could be an aim, variable anything. 
 Lets suppose you receive user profile from database, and you desire to cache it so the next requests wo nt be necessitate to fetch from db. You would cache it in APC after the beginning fetch from db.   this is an example of where you might use APC drug user hoard 
          $ userObject->name = " Mike "; 
          $ userObject- > age = 12; 
          apc_store("user ", $ userObject); 

 You can retrieve the value, with the keystone which is user.
