vector《型別》識別符號(最大容量)
vector《型別》識別符號(最大容量,初始所有值)
int i[5]=
vector《型別》vi(i,i+2);//得到i索引值為3以後的值
vector< vector< int> >v; 二維向量//這裡最外的<>要有空格。否則在比較舊的編譯器下無法通過
clear();//清除容器中所以資料 不會 釋放記憶體
data（）//列印 記憶體區塊
push_back(i); //尾部 install data
pop.back(i) //delete top data
capacity（）// 返回vector的實際儲存空間的大小，這個一般大於或等於vector元素個數，注意與size()函式的區別
#include //使用 swap
erase()// 直接用 會產生 野指標問題 配合 remove_if() 使用
vectora; //建立乙個空的的容器
vectorb(10,100); //建立乙個10個元素,每個元素值為100
vectorc(b.begin(),b.end()); //使用迭代器,可以取部分元素建立乙個新的容器
vectord(c); //複製建構函式,建立乙個完全一樣的容器
//過載=

vector類基本用法
vector類為內建陣列提供了一種替代表示，與string類一樣 vector 類是隨標準 c 引入的標準庫的一部分 為了使用vector 我們必須包含相關的標頭檔案 include 使用vector有兩種不同的形式，即所謂的陣列習慣和 stl習慣。1.定義乙個已知長度的 vector vector...
vector的基本用法
vector是c 標準模板庫中的部分內容，它是乙個多功能的，能夠操作多種資料結構和演算法的模板類和函式庫。vector之所以被認為是乙個容器，是因為它能夠像容器一樣存放各種型別的物件，簡單地說，vector是乙個能夠存放任意型別的動態陣列，能夠增加和壓縮資料。標頭檔案 include 宣告 乙個in...
vector的基本用法
include include vector的標頭檔案 using namespace std int main if num.empty 判斷容器是否為空,為不的意思 num.pop back 去掉尾部的最後乙個元素 num.at 2 88 索引的方式修改第二個元素為88 num 5 66 下標的...
