Any difference in the binary?

[ninja9578]

class foo {
public:
   foo(void) : f1("test"), f2(5){}
private:
   string f1;
   int f2;
}

class bar {
public:
   bar(void) : f2(5), f1("test"){}
private:
   int f2;
   string f1;
}

Does the order make any difference in performance?


Also, any difference in this?

void * ptr = NULL;
if (ptr){  something }

...

if (ptr != NULL) { something }

different compilers warn about these things, but I'm almost certain all compilers would be smart enough to do the != NULL implicitly.
