Assigned '\0' to the first element.

i did this and cleared the string and it still is doing the same thing??

void showNewData() {
    if (newData == true) {
        Serial.print("This just in ... ");
        Serial.println(receivedChars);
       if (strcmp(receivedChars, "test 2") == 0) {
       Serial.println("working 2");



  }
        newData = false;
    } 
           if (strcmp(receivedChars, "test 1") == 0) {
       Serial.println("working 1");
      receivedChars[numChars] = '\0';  
  }

also when it keeps printing working 1 if i type test 2 it prints test 2 q time and stops like its suppose to?
