operator<= (set)

Tests if the set object on the left side of the operator is less than or equal to the set object on the right side.

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

_Left

An object of type set.

_Right

An object of type set.

true if the set on the left side of the operator is less than or equal to the set on the right side of the operator; otherwise false.

The comparison between set 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.

}
Set s1 is less than or equal to the set s2.
The set s1 is greater than the set s3.
Set s1 is less than or equal to the set s4.
