1.vector 的數據的存入和輸出：

#include<stdio.h>
#include<vector>
#include <iostream>

using namespace std;

void main()

{

   int i = 0;

    vector<int> v;

    for( i = 0; i < 10; i++ )

   {

             v.push_back( i );//把元素一個一個存入到vector中

   }

   for( i = 0; i < v.size(); i++ )//v.size() 表示vector存入元素的個數

   {

          cout << v[ i ] << "  "; //把每個元素顯示出來

   }

   cont << endl;

} 

注：你也可以用v.begin()和v.end() 來得到vector開始的和結束的元素地址的指針位置。你也可以這樣做：

vector<int>::iterator iter;

for( iter = v.begin(); iter != v.end(); iter++ )

{
    cout << *iter << endl;
}

2. 對于二維vector的定義。

1)定義一個10個vector元素，并對每個vector符值1-10。

#include<stdio.h>
#include<vector>
#include <iostream>

using namespace std;

void main()
{
 int i = 0, j = 0;

//定義一個二維的動態數組，有10行，每一行是一個用一個vector存儲這一行的數據。

所以每一行的長度是可以變化的。之所以用到vector<int>(0)是對vector初始化，否則不能對vector存入元素。
 vector< vector<int> > Array( 10, vector<int>(0) ); 

for( j = 0; j < 10; j++ )
 {
  for ( i = 0; i < 9; i++ )
  {
   Array[ j ].push_back( i );
  }
 }

 for( j = 0; j < 10; j++ )
 {
  for( i = 0; i < Array[ j ].size(); i++ )
  {
   cout << Array[ j ][ i ] << "  ";
  }
  cout<< endl;
 }
}

2)定義一個行列都是變化的數組。

#include<stdio.h>
#include<vector>
#include <iostream>

using namespace std;

void main()
{
 int i = 0, j = 0;

 vector< vector<int> > Array;
 vector< int > line;
 for( j = 0; j < 10; j++ )
 {
  Array.push_back( line );//要對每一個vector初始化，否則不能存入元素。
  for ( i = 0; i < 9; i++ )
  {
   Array[ j ].push_back( i );
  }
 }

 for( j = 0; j < 10; j++ )
 {
  for( i = 0; i < Array[ j ].size(); i++ )
  {
   cout << Array[ j ][ i ] << "  ";
  }
  cout<< endl;
 }
}

下面是我找的一些常用vector類的成員函數~

push_back()插入一個元素
pop_back() 可以彈出最后ch一個元素
erase(iterator   it)可以刪除指定位置的元素
size（）求vector中的已存的元素個數
clear（）可以清空vector中的元素

Vector constructors	create vectors and initialize them with some data
Vector operators	compare, assign, and access elements of a vector
assign	assign elements to a vector
at	returns an element at a specific location
back	returns a reference to last element of a vector
begin	returns an iterator to the beginning of the vector
capacity	returns the number of elements that the vector can hold
clear	removes all elements from the vector
empty	true if the vector has no elements
end	returns an iterator just past the last element of a vector
erase	removes elements from a vector
front	returns a reference to the first element of a vector
insert	inserts elements into the vector
max_size	returns the maximum number of elements that the vector can hold
pop_back	removes the last element of a vector
push_back	add an element to the end of the vector
rbegin	returns a reverse_iterator to the end of the vector
rend	returns a reverse_iterator to the beginning of the vector
reserve	sets the minimum capacity of the vector
resize	change the size of the vector
size	returns the number of items in the vector
swap	swap the contents of this vector with another
