title: creating vectors of character pointers to point to vector of strings
body: <p>I have a vector of strings: vectorElements
  I'd like to create a vector of *char to point to the beginning of each string. My objective is to be able to traverse through each string, character by character. Ultimately, I'd like to sort the vector of strings. 
  Note: Strings may contain integer values. In which case, I'll be sorting based on their numeric value. </p>
