operator< (<vector>)

Tests if the object on the left side of the operator is less than the object on the right side.

bool operator<(
   const vector<Type, Allocator>& _Left,
   const vector<Type, Allocator>& _Right
);

Parameters

• _Left
  An object of type vector.

• _Right
  An object of type vector.

Return Value

true if the vector on the left side of the operator is less than the vector on the right side of the operator; otherwise false.

Example

// vector_op_lt.cpp
// compile with: /EHsc
#include <vector>
#include <iostream>

int main( )
{
   using namespace std; 
   
   vector <int> v1, v2;
   v1.push_back( 1 );
   v1.push_back( 2 );
   v1.push_back( 4 );

   v2.push_back( 1 );
   v2.push_back( 3 );

   if ( v1 < v2 )
      cout << "Vector v1 is less than vector v2." << endl;
   else
      cout << "Vector v1 is not less than vector v2." << endl;
}

Vector v1 is less than vector v2.
