vector操作

1、一次性打印vector中的所有元素

2、将两个vector元素组合到一个vector中

3、利用函数 max_element，min_element，distance可以获取Vector中最大、最小值的值以及位置索引

using namespace std;

cout<<"***A******"<<endl;

copy (A.begin(), A.end(), ostream_iterator<float> (cout, "\n"));// 打印A的元素

cout<<"***B******"<<endl;

copy (B.begin(), B.end(), ostream_iterator<float> (cout, "\n"));

cout<<"****new A******"<<endl;

A.insert(A.end(),B.begin(),B.end());//合并B到A

copy (A.begin(), A.end(), ostream_iterator<float> (cout, "\n"));

vector<double>::iterator maxValue = max_element(begin(A),end(A));

cout << "Max element is " << *maxValue<< " at position " <<distance(begin(A),maxValue)<<endl;

auto minValue = std::min_element(begin(A), std::end(A));

cout << "min element is " << *minValue<< " at position " <<distance(begin(A),maxValue)<<endl;

return 0;
