It must be the debugging, the compiler or a poor STL implementation. With
gcc 4 it runs instantly on my computer (using -O2), even with 10x the
number of values.
If the problem is that C++ has to make lots of new strings, as other posters
have suggested, then you could do something like
const string foo = "What do you know?";
for (long int i=0; i<10000 ; ++i){
a.push_back(foo);
...
}
as many C++ implementations use reference counting for identical strings.
