转自:STL vector用法介绍 介绍 这篇文章的目的是为了介绍std::vector,如何恰当地使用它们的成员函数等操作。本文中还讨论了条件函数和函数指针在迭代算法中使用,如在remove_if()和for_each()中的使用。通过阅读这篇文章读者应该能够有效地使用vector容器,而且应该不会再去使用C类型的动态数组了。
// Functions: // // vector::front - Returns reference to first element of vector. // // vector::back - Returns reference to last element of vector. // // vector::push_back - Appends (inserts) an element to the end of a

In this example, we are demonstrating the examples of vector::front(), vector::back(), vector::at() and vector::data() functions in C++ STL: #include <iostream>#include <vector>usingnamespacestd;intmain() {// declare vectorvector<int>num{10,20,30,40,50};// vector::front ()cout...
