Although stringstream is very convenient to us , 

but sometimes we can also use c method to split the string.

first , we need to convert string to c_string style. (char*)

then , we can use strtok to split this string by specific format.

#include <iostream> 

#include <cstring> 

#include <string> 

using namespace std; 

int main () 

{ 

char * cstr, 

*p; string str ("Please split this phrase into tokens"); 

cstr = new char [str.size()+1]; 

strcpy (cstr, str.c_str()); 

// cstr now contains a c-string copy of str 

p=strtok (cstr," "); 

while (p!=NULL) 

{ 

cout << p << endl; 

p=strtok(NULL," "); 

} 

delete[] cstr; 

return 0; 

}
