Set std::vector to a range

Question

What\'s the best way for setting an std::vector to a range, e.g. all numbers between 3 and 16?

Answer 1

You could use std::iota if you have C++11 support or are using the STL:

std::vector v(14);
std::iota(v.begin(), v.end(), 3);

or implement your own if not.

If you can use boost, then a nice option is boost::irange:

std::vector v;
boost::push_back(v, boost::irange(3, 17));
