Comparatia aceasta nu e relevanta, in varianta C++ folosesti iostream,
care include multe alte headere, ia uite ce genereaza preprocesorul:
$ g++ -E HelloWorld.cpp|wc -l

incercati cu 'precompiled headers'.
se zice ca cei de la Apple fac minuni in IDE-urile
lor cu asta ... (gcc/g++ compileaza programul in
timp ce-l scrii)
ex.
$ cat a.h
#include <iostream>
$ cat a.cc
#include "a.h"
using namespace std;
int
main()
{
cout << "hallo baby" << endl;
return 0;
}
$ time g++ -Wall -O2 a.cc
g++ -Wall -O2 a.cc 1.59s user 0.09s system 96% cpu 1.736 total
$ g++ -Wall -O2 a.h && rm a.h
$ time g++ -Wall -O2 a.cc
g++ -Wall -O2 a.cc 0.16s user 0.06s system 86% cpu 0.248 total
