title: How to use Strtok for tokenizing a Const char*?
body: <p>I have a const char* variable which may have a value like "OpenStack:OpenStack1". I want to tokenize this const char* using strtok where the delimiter(which is of a const char* type) is ":" . But the problem is strtok is of following type:
  char * strtok ( char * str, const char * delimiters );</p>
  
  <p>Which means I can't use const char* for the first input as it has to be char*. Could you say me how I can convert this const char* into char*?</p>
  
  <p>Thank you.</p>
