删除元素列表的末尾。
void pop_back( );
备注
最后一个元素不能为空。pop_back 永远不会引发异常。
示例
// list_pop_back.cpp
// compile with: /EHsc
#include <list>
#include <iostream>
int main( ) 
{
   using namespace std;
   list <int> c1;
   
   c1.push_back( 1 );
   c1.push_back( 2 );
   cout << "The first element is: " << c1.front( ) << endl;
   cout << "The last element is: " << c1.back( ) << endl;
   c1.pop_back( );
   cout << "After deleting the element at the end of the list, "
           "the last element is: " << c1.back( ) << endl;
}
