Int tokenizer

Question

I know there are string tokenizers but is there an "int tokenizer"?

For example, I want to split the string "12 34 46" and have:

Answer 1

Yes there is: use a stream, e.g. a stringstream:

stringstream sstr("12 34 46");
int i;
while (sstr >> i)
    list.push_back(i);

Alternatively, you can also use STL algorithms and/or iterator adapters combined with constructors:

vector list = vector(istream_iterator(sstr), istream_iterator());
