一、vector三种遍历方式
- fori
- for
- iterator
二、遍历及调用注意事项
引用传递避免复制
#include<iostream>
#include<vector>struct Vertex {int x, y, z;
};//重定义输出 Vertex 数据
std::ostream& operator<<(std::ostream& stream, const Vertex& tex) {stream << tex.x << " , " << tex.y << " , " << tex.z;return stream;
}//参数要用引用方式设置，否则会复制
void Funtion(const std::vector<Vertex>& vertex) {}void testVector() {std::vector<Vertex> dynamicArr;dynamicArr.push_back({ 1, 2, 3 });dynamicArr.push_back({ 4, 5, 6 });for (int i = 0; i < dynamicArr.size(); i++) {std::cout << dynamicArr[i] << std::endl;}dynamicArr.erase(dynamicArr.begin() + 1);std::cout << " -------------- " << std::endl;//此处要用引用，否则会复制for (Vertex& vertex : dynamicArr) {std::cout << vertex << std::endl;}
}int main() {testVector();std::cin.get();
}
