// Now use this new predicate in a call to find_if

iterator it1 = find_if(v1.begin(),v1.end(),equal_to_3);

// Even better, construct the new predicate on the fly

iterator it2 =

find_if(v1.begin(),v1.end(),bind1st(equal_to<int>(),3));

// And now the same thing using bind2nd

// Same result since == is commutative

iterator it3 =

find_if(v1.begin(),v1.end(),bind2nd(equal_to<int>(),3));

// it3 = v1.begin() + 2

// Output results

cout << *it1 << " " << *it2 << " " << *it3 << endl;

return 0;

}

Output : 3 3 3

Warnings

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>
