The template function is an algorithm specialized on the container class vector to execute the member functionleft. vector::swap (right). These are instances of the partial ordering of function templates by the compiler. When template functions are overloaded in such a way that the match of the...

❮ Vector Functions Example Swap the contents of two vectors: vector<string>cars={"Volvo","BMW","Ford","Mazda"};vector<string>fruits={"Apple","Banana","Cherry","Orange"};cars.swap(fruits);cout<<"Cars:\n";for(string car:cars){cout<<car<<"\n";}cout<<"\nFruits:\n";for(string...
This article delves into various strategies for returning vectors from functions in C++ 2. Returning by Value The simplest and most straightforward method to return a vector from a function is by value. This technique involves creating a local vector within the function and returning it directly. ...

The above insert() function will work insert the range of elements before the position of the vector element mentioned by the position argument. It returns an iterator that points to the newly inserted elements of the vector, like the previous two insert() functions. ...
std map是STL的一个关联容器,它提供一对一(其中第一个可以称为关键字,每个关键字只能在map中出现一次,第二个可能称为该关键字的值)的数据处理能力,由于这个特性,它完成有可能在我们处理一对一数据的时候,在编程上提供快速通道。这里说下std map内部数据的组织,std map内部自建一颗红黑树(一种非严格意义上的平衡...
