How comparator is behaving in the binary search function

#1

I have looked into the c++ references about the binary search function.I do not have a slight idea what the values are coming into the comparator function and what happens after the comparator function returns a true or false.
Please help me with that.

#2

Please provide us with a code snippet or something which you are stuck at so that we can help you out with it.

#3

if (std::binary_search (v.begin(), v.end(), 6, myfunction)) std::cout << “found!\n”; else std::cout << “not found.\n”;

#4

The built-in binarySearch function always supplies the pivot element to the comparator as the second argument. This is undocumented behaviour, but we can exploit that using a given comparator
