Using std::copy()
, it can be done like this:
#include <iostream>
#include <vector>
#include <algorithm>
void printVector(const std::vector<int>& v) {
bool first = true;
std::cout << '{';
for (int i : v) {
if (!first) std::cout << ", ";
std::cout << i;
first = false;
}
std::cout << "}
";
}
int main(void) {
std::vector<int> v1 = {1, 2, 3, 4, 5, 6, 7};
std::vector<int> v2 = {6, 6, 3, 5, 4, 13, 99};
printVector(v1);
printVector(v2);
std::vector<int>::iterator dest_begin = v1.begin();
std::vector<int>::iterator src_begin = std::next(v2.begin(), 1);
std::vector<int>::iterator src_end = std::next(v2.begin(), 5);
std::copy(src_begin, src_end, dest_begin);
printVector(v1);
return 0;
}
Output:
{1, 2, 3, 4, 5, 6, 7}
{6, 6, 3, 5, 4, 13, 99}
{6, 3, 5, 4, 5, 6, 7}
与恶龙缠斗过久,自身亦成为恶龙;凝视深渊过久,深渊将回以凝视…
