The Copy Algorithm

The Copy Algorithm

The Standard Library provides a generic copy function, which can be used to copy a sequence of objects to a specified target. The first and the second arguments of copy() are const iterators that mark the sequence’s beginning and its end, respectively. The third argument points to a container into which the sequence is copied. The following example demonstrates how to copy the elements of a list into a vector:

 #include #include#includeusing namespace std;void main() {  list li; vector  vi;  li.push_back(1);   // fill the list with elements  li.push_back(2);  vi.reserve( li.size() );  // a vector must make room for copied elements in advance   copy (li.begin(), li.end(), vi.begin() );  //copy list elements into vector, starting at vector's beginning}
