upper_bound(v1.begin(),v1.end(),2,less<int>());

// it4 = v1.begin() + 5

cout << endl << endl

<< "The upper and lower bounds of 3: ( "

<< *it1 << " , " << *it3 << " ]" << endl;

cout << endl << endl

<< "The upper and lower bounds of 2: ( "

<< *it2 << " , " << *it4 << " ]" << endl;

return 0;

}

Output :

The upper and lower bounds of 3: ( 3 , 4 ]

The upper and lower bounds of 2: ( 2 , 3 ]

Warning

If your compiler does not support default template parameters then you need to always supply

the Allocator template argument. For instance you'll have to write:

vector<int,allocator>

instead of:

vector<int>
