Read and Write Strings Using String Streams

String streams allow reading and writing strings just like cin and cout allow reading standard input and writing standard output. String streams may be used by including <sstream>.

Reading from a string is similar to reading input using cin:

string s = "word 5";
istringstream iss(s);
string w;
int n;
iss >> w >> n;
Writing to a string is similar to writing output using cout:

ostringstream oss;
oss << "This is a number: " << 5;
string s = oss.str();
