如今关心一下别的:注意是insert后,被insert的vector为多少了: #include<iostream>#include<vector>intmain(){std::vector<int>myvector(3,100);std::vector<int>anothervector(2,400); std::cout <<"Before insert myvector is:";for(autoit = myvector.begin(); it<myvector.end(); it++) std::cout...
myvector.insert (it,2,300);// "it" no longer valid, get a new one:it = myvector.begin(); std::vector<int> anothervector (2,400); myvector.insert (it+2,anothervector.begin(),anothervector.end());intmyarray [] = { 501,502,503 }; myvector.insert (myvector.begin(), myarray...

3. Insert Another Vector Further, we can also insert elements of another vector to our old vector. Just we need to pass an iterator pointing to the position in our vector where we need to insert another vector. Along with that, the iterators pointing to the starting and end of the second...
Insert a range of elements from another vector: vector<string> cars = {"Volvo", "BMW", "Ford", "Mazda"}; vector<string> newcars = {"Toyota", "Mercedes"}; cars.insert(cars.begin() + 2, newcars.begin(), newcars.end()); for (string car : cars) { cout << car << "\n";...
insert(vec.end(), another_vec.begin(), another_vec.end()); // 在末尾插入another_vec的所有元素,结果为{1, 4, 2, 3, 5, 6} 3. 从C++的vector中删除元素 从vector中删除元素通常使用erase()方法。 erase():该方法可以删除单个元素或指定范围内的元素。删除操作会返回指向被删除元素之后第一个...
In my program, I have a class Route. It has a vector<string> property. After an initial vector has been populated, the user may have to concatenate another vector<string> to that initial vector. How can I overload the '+' operator to add to Route objects together and return the concat...
