mem usage?

I just had a young programmer tell me that an uninitialized std::string uses less memory than an initialized one. Is that true? (I guess that would depend on the implementation; but consider, for example gcc) The code I found suspect was:

class blah {
  private:
     std:string name;
  public:
     blah (std:string in) {
        if (!in.empty()) name = in;  // claimed savings of memory
     } 
 };

That sounds bogus to me. Even if you don't touch name, it gets initialized at the beginning of the constructor. —Ben FrantzDale (talk) 06:10, 27 January 2008 (UTC)[reply]
