C++: string operator overload

Question

Can I overload existing function/operator in existing class?

I was trying to do:

#include 
#include 
using namespace std;

         


        

Answer 1

Use

std::ostringstream

#include 
#include 

using namespace std;

int main()
{
    std::ostringstream ss;
    ss << "Hello" << " " << "world";

    std::string s = ss.str(); 
    ss.str(std::string()); 

    cout << s << endl;
    return 0;
}
