strstream in c++

Question

I am writing the code

#include<sstream>
#include<iostream>

using namespace std;
int main(){
strstream temp;

int t =10;
temp>>10;

string tt ="testing"+temp.str();

Have a problem, it does not work at all for the temp variable, just get in result only string testing without 10 in the end?

}

Answer 1

You should use operator<<() instead, temp << 10;.
