For that purpose we will use '/u' character. UNICODE-8 is on 2 bytes, 4 digits. See next example:
unicode_example_in_c.cc #include <iostream>
using namespace std;
int main (void )
{
char const *greek = "\u03A9\u03A8\u03EA";
printf("char: %s\n", greek );
}

We can use a stringstream variable for that. See next example:
example1 #include <iostream>
#include <sstream>
using namespace std;
int main (void )
{
stringstream sstream;
int var= 100;
sstream << var;
cout << sstream.str () << endl;
}
If we later asign other value to sstream variable, we must first clear it. See next example:
example2 #include <iostream>
#include <sstream>
using namespace std;
int main (void )
{
stringstream sstream;
int var= 100, var2= 200, var3= 300;
sstream << var;
cout << sstream.str () << endl;
sstream << var2;
cout << sstream.str () << endl;
sstream.str (""); // this will clear sstream var
sstream << var3;
cout << sstream.str () << endl;
}
