构造函数采用单个模板类型参数,因为构造函数的两个参数都是相同的类型。您提供了两个
将您的搜索声明更改为:
boost::algorithm::boyer_moore<std::string::const_iterator>
search(pattern.begin(), pattern.end());
boost::algorithm::boyer\u moore
搜索(pattern.begin(),pattern.end());
它会起作用的
#include <iostream>
#include <string>
#include <boost/algorithm/searching/boyer_moore.hpp>
int main() {
std::string corpus("hello world");
std::string pattern("hello");
boost::algorithm::boyer_moore<std::string::const_iterator, std::string::const_iterator>
search(pattern.begin(), pattern.end());
if (corpus.end() != search(corpus.begin(), corpus.end()))
{
std::cout << "pattern found" << std::endl;
}
return 0;
