operator!= (<list>)

Tests if the list object on the left side of the operator is not equal to the list object on the right side.

bool operator!=(
   const list<Type, Allocator>& _Left,
   const list<Type, Allocator>& _Right
);

Parameters

  • _Left
    An object of type list.

  • _Right
    An object of type list.

Return Value

true if the lists are not equal; false if the lists are equal.

Remarks

The comparison between list objects is based on a pairwise comparison of their elements. Two lists are equal if they have the same number of elements and their respective elements have the same values. Otherwise, they are unequal.

Example

// list_op_ne.cpp
// compile with: /EHsc
#include <list>
#include <iostream>

int main( ) 
{
   using namespace std; 
   list <int> c1, c2;
   c1.push_back( 1 );
   c2.push_back( 2 );

   if ( c1 != c2 )
      cout << "Lists not equal." << endl;
   else
      cout << "Lists equal." << endl;
}

Output

Lists not equal.
