C++17 in Detail: A Deep Dive

Using Searchers

The lesson will elaborate the syntax and methods for using Searchers.

We'll cover the following...

The std::search function uses the following overload for searchers:

C++
template<class ForwardIterator, class Searcher>
ForwardIterator search(ForwardIterator first, ForwardIterator last, const Searcher& searcher );

For example:

C++ 17
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;
int main(){
    string testString = "Hello Super World";
    string needle = "Super";
    const auto it = search(begin(testString), end(testString), boyer_moore_searcher(begin(needle), end(needle)));
    if (it == cend(testString))
        cout << "The string " << needle << " not found\n";
    return 0;
}

Each searcher initializes its state ...
