operator== (<deque>)
Tests if the deque object on the left side of the operator is equal to the deque object on the right side.
bool operator==(
const deque<Type, Allocator>& _Left,
const deque<Type, Allocator>& _Right
);
Parameters
_Left
An object of type deque._Right
An object of type deque.
Return Value
true if the deque on the left side of the operator is equal to the deque on the right side of the operator; otherwise false.
Remarks
The comparison between deque objects is based on a pairwise comparison of their elements. Two deques are equal if they have the same number of elements and their respective elements have the same values. Otherwise, they are unequal.
Example
// deque_op_eq.cpp
// compile with: /EHsc
#include <deque>
#include <iostream>
int main( )
{
using namespace std;
deque <int> c1, c2;
c1.push_back( 1 );
c2.push_back( 1 );
if ( c1 == c2 )
cout << "The deques are equal." << endl;
else
cout << "The deques are not equal." << endl;
c1.push_back( 1 );
if ( c1 == c2 )
cout << "The deques are equal." << endl;
else
cout << "The deques are not equal." << endl;
}
The deques are equal. The deques are not equal.
