How to use boost string algorithm starts_with: A minimal example

#include <boost/algorithm/string/predicate.hpp>
#include <string>
#include <iostream>

int main() {
    std::string mystr = "foobar";
    // Prints "true, false"
    std::cout << std::boolalpha
        << boost::algorithm::starts_with(mystr, "foo") << ", "
        << boost::algorithm::starts_with(mystr, "bar") << std::endl;
}
