vector::operator=

用另一個向量複本取代向量的項目。

vector& operator=(
   const vector& _Right
);
vector& operator=(
   vector&& _Right
);

參數

備註

在清除在 vector的任何現有項目之後， operator= 複製或移動到 _Right 內容 vector。

範例

// vector_operator_as.cpp
// compile with: /EHsc
#include <vector>
#include <iostream>

int main( )
{
   using namespace std;
   vector<int> v1, v2, v3;
   vector<int>::iterator iter;

   v1.push_back(10);
   v1.push_back(20);
   v1.push_back(30);
   v1.push_back(40);
   v1.push_back(50);

   cout << "v1 = " ;
   for (iter = v1.begin(); iter != v1.end(); iter++)
      cout << *iter << " ";
   cout << endl;

   v2 = v1;
   cout << "v2 = ";
   for (iter = v2.begin(); iter != v2.end(); iter++)
      cout << *iter << " ";
   cout << endl;

// move v1 into v2
   v2.clear();
   v2 = move(v1);
   cout << "v2 = ";
   for (iter = v2.begin(); iter != v2.end(); iter++)
      cout << *iter << " ";
   cout << endl;
}

Output

v1 = 10 20 30 40 50 
v2 = 10 20 30 40 50 
v2 = 10 20 30 40 50
