我想知道以下代码的含义
我只是想知道它是如何工作的。
vector<int> lotteryNumVect(10); // I do not understand this part.
int lotteryNumArray[5] = {4, 13, 14, 24, 34}; // I understand this part.
lotteryNumVect.insert(lotteryNumVect.begin(), lotteryNumArray,
lotteryNumArray + 3); // I do not understand this part.
cout << lotteryNumVect.at(2) << endl; // I understand this part.
