Concatenating Variables


If you need to concatenate variables of different types to form a string, use a stringstream object. The header <sstream> contains the declarations of the stringstream family of classes. Using its overloaded << operators, stringstream will convert variables of built-in types such as int, double and char * into a string and store the result in its internal buffer. To extract the resulting string, use the >> operator:
  
#include <sstream>
void concat(std::string &result)
{
 long x = 1000;
 double y = 5.5.;
 std::stringstream s;
 s << "(" << x << "," << y << ")";
 s>>result; // result is now "(1000,5.5)"
}
