用另一个向量替换向量的一部分

Question

I have a vector of size 20 and a second of size 5. I wish to replace elements 11-15 in the first vector with the second vector. I can do this by deleting those elements from the first vector and inserting the second vector. Is there another way to do this, perhaps by using assign?

Answer 1

You can use std::copy :

#include <algorithm> // for std::copy

std::copy(src.begin(), src.end(), dst.begin()+10);

where src is the size 5 vector, and dst is the size 20 vector.
