operator== (<list>)

Tests if the list object on the left side of the operator is 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 list on the left side of the operator is equal to the list on the right side of the operator; otherwise false.

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_eq.cpp
// compile with: /EHsc
#include <list>
#include <iostream>
int main( ) 
{
   using namespace std; 
   
   list <int> c1, c2;
   c1.push_back( 1 );
   c2.push_back( 1 );

   if ( c1 == c2 )
      cout << "The lists are equal." << endl;
   else
      cout << "The lists are not equal." << endl;
}
The lists are equal.
