stream to string cpp code example

Example 1: convert string to stream c++

// stringstream::str
#include <string>       // std::string
#include <iostream>     // std::cout
#include <sstream>      // std::stringstream, std::stringbuf

int main () {
  std::stringstream ss;
  ss.str ("Example string");
  std::string s = ss.str();
  std::cout << s << '\n';
  return 0;
}

Example 2: stringstream in c++

std::stringstream os;
os << "12345 67.89"; // insert a string of numbers into the stream

std::string strValue;
os >> strValue;

std::string strValue2;
os >> strValue2;

// print the numbers separated by a dash
std::cout << strValue << " - " << strValue2 << std::endl;
