I want to copy a row from a 2d vector in an existing 1d vector. I found a similar tread, which copies into a newly defined vector as such:
vector< data_type > copyRow( vec2d.begin(), vec2d.end());
Now I want to change this code, so that copyRow already exists. My idea was (to copy row three for example):
copyRow.clear; copyRow.insert( vec2d.begin(), vec2d.end());
Unfortunately, this gives me an error:
error: no matching function for call to ‘std::vector<int>::insert(std::vector<int>::iterator, std::vector<int>::iterator)’
I have included vector, so I am guessing this has something to do with the fact that 2d vectors have another type of vectoriterator? I can't use the insert function?
Thanks for any ideas...
