operator>= (multiset)

如果在运算符左侧的多个对象集大于或等于右侧，的多级集测试对象。

bool operator!>=(
   const multiset <Key, Traits, Allocator>& _Left,
   const multiset <Key, Traits, Allocator>& _Right
);

参数

• _Left
  multiset 类型的对象。

• _Right
  multiset 类型的对象。

返回值

true，如果在运算符左侧的多个集大于或等于多个集列表中的右侧;否则 false。

备注

在将多个对象之间的比较根据其元素的比较pairwise。大于或等于两个对象之间的关系于比较的第一对不相等元素。

示例

// multiset_op_ge.cpp
// compile with: /EHsc
#include <set>
#include <iostream>

int main( )
{
   using namespace std;
   multiset <int> s1, s2, s3, s4;
   int i;

   for ( i = 0 ; i < 3 ; i++ )
   {
      s1.insert ( i );
      s2.insert ( i * i );
      s3.insert ( i - 1 );
      s4.insert ( i );
   }

   if ( s1 >= s2 )
      cout << "The multiset s1 is greater than "
           << "or equal to the multiset s2." << endl;
   else
      cout << "The multiset s1 is less than "
           << "the multiset s2." << endl;

   if ( s1 >= s3 )
      cout << "The multiset s1 is greater than "
           << "or equal to the multiset s3." << endl;
   else
      cout << "The multiset s1 is less than "
           << "the multiset s3." << endl;

   if ( s1 >= s4 )
      cout << "The multiset s1 is greater than "
           << "or equal to the multiset s4." << endl;
   else
      cout << "The multiset s1 is less than "
           << "the multiset s4." << endl;
}
