What follows is not a class:
class A
{
}
But this is:
class A
{
};
You should
#include <string>
if you plan to use std::string and pass it by reference to functions
or you'll end up invoking std::string copy ctor unneccessarily. Not to
mention that you'ld be modifying a local only.
void foo( std::string& r_s ) // or const std::string&
{
// do stuff with r_s
}
All of the above is basic, fundamental, unavoidable, required
knowledge.
What book are you reading?
