operator<= (<list>)
Tests if the list object on the left side of the operator is less than or 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 less than or 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. The less than or equal to relationship between two objects is based on a comparison of the first pair of unequal elements.
Example
// list_op_le.cpp
// compile with: /EHsc
#include <list>
#include <iostream>
int main( )
{
using namespace std;
list <int> c1, c2;
c1.push_back( 1 );
c1.push_back( 2 );
c1.push_back( 4 );
c2.push_back( 1 );
c2.push_back( 3 );
if ( c1 <= c2 )
cout << "List c1 is less than or equal to list c2." << endl;
else
cout << "List c1 is greater than list c2." << endl;
}
List c1 is less than or equal to list c2.
