istringstream is("hello world hello earth" );
string s,str;
str = is.str() ; //str = hello world hello earth
is >> s; //s = hello
str = is.str(); //str still = hello world hello earth

But i want the rest "world hello earth", what can I do?

is >> s; //s = hello
string s2;
getline (is, s2); // s2 = world hello earth
