token

is there any function in c++ which is the same as strtok() function in c,if there is can u give a simple example

strtok() can be used in c++ the same way its used in c
just include <cstring>

If you mean with C style strings then you can just use strtok in <cstring>, if you mean with the string class then you can do something like this

Code:

#include <iostream>
#include <string>

string bad_char = " ";

string next_token(string& s, string::size_type& pos)
{
  size_t begin = s.find_first_not_of(bad_char, pos);
  size_t end = s.find_first_of(bad_char, begin);

  pos = end;

  if (begin == string::npos)
  {
    return string();
  }
  else if (end == string::npos)
  {
    return s.substr(begin);
  }
  else
  {
    return s.substr (begin, end - begin);
  }
}

int main()
{
  string::size_type pos = 0;
  string s = "Breaking up a string";
  string t;

  while (!(t = next_token(s, pos)).empty())
  {
    cout<< t <<endl;
  }
}
