stl - C++ convert vector<int> to vector<double>

Question

What is a good clean way to convert a std::vector<int> intVec to std::vector<double> doubleVec. Or, more generally, to convert two vectors of convertible types?

Answer 1

Use std::vector's range constructor:

std::vector<int> intVec;
std::vector<double> doubleVec(intVec.begin(), intVec.end());
