trying to update char array from string

i'm trying create message can send twitter based on converting string char array use twitter library.  problem i'm having char array not seem updated through sketch - stays @ original value.  there easier/better way generate message can send using twitter library, includes short status word , date /time?

here code:

code: [select]


string test ;
int k = 0;
int i;
char msg[130];


void setup()
{
  serial.begin(9600);
}
void loop() {
  while (k < 10) {
    test = "string " + string(k);
    serial.println(test);
    ( == 0; <= test.length(); i++) {
      msg[i] = test.charat(i);
    }
    serial.println(msg);
    k++;
    delay(500);
  }
}



here's output get:

string 0
string 0
string 1
string 0
string 2
string 0
string 3
string 0
string 4
string 0
string 5
string 0
string 6
string 0
string 7
string 0
string 8
string 0
string 9
string 0

code: [select]

    ( == 0; <= test.length(); i++) {
      msg[i] = test.charat(i);
    }
the == 0 bit wrong. not initialize i.
