VL64 and B64 encoding functions ~ C++

    This probably won't be of use to those of you who've moved onto the new crypto, but oh well.
    Pretty self explanatory, it's a stable port of the VL64 and B64 encoding functions written by Jeax (I believe) and Jordan (his Java port provided the basis for this).
    VL64 function
    PHP Code:
    static string Encode_VL64(int i){
        string s = "";
        char res[6]; //assign the var res to a a char array - len6
          int p = 0; 
     int sP = 0;
     int bytes = 1;
     int negativeMask = i >= 0 ? 0 : 4; //? : = if else clause
     i = abs(i);
     res[p++] = (char)(64 +(i & 3));
     for (i >>= 2; i != 0; i >>= 6){
         bytes++;
         res[p++] = (char)(64 + (i & 0x3f));
     }
     int null = 0;
     res[sP] = (char)(res[sP] | bytes << 3 | negativeMask);
      string tmp =  string(res);
    tmp.erase(2,22); //clever little method to cut the string. 
    //If this was not done, the output would have extremely weird chars.
      return tmp;

    } 
    B64 function
    PHP Code:
    static string Encode_B64(int i){
    string s = "";
     for (int x = 1; x <= 2; x++){
                    s += (char)((char)(64 + (i >> 6 * (2 - x) & 0x3f)));
    }
     return s;
    } 
    Usage:
    PHP Code:
    #include <iostream>
    #include <string>
    #include <math.h>
    using namespace std;
    int main()
    {
    int value;
    cout << "Enter your value\n";
    cin >> value;
    cout << //either: Encode_B64(value) or Encode_VL64(value);
    cin.get()
    return 0;
    }
