问题描述

我看着模板定义以及参数似乎想通过一系列和predicate迭代器。我在一个vector.begin(通过),...端(),并为std :: string predicate但仍获得提振相关库项目的主持人很多编译时错误。我可以看到使用的boost ::算法的一个明显的例子::包含好吗?

I looked at the template definition and the parameters appear to want iterators across a range and a predicate. I passed in a vector.begin(), ...end(), and a std::string predicate but still get many compile time errors related a host of boost library items. Can I see a clear example of the use of boost::algorithm::contains please?

推荐答案

这是相当简单的,我猜你是通过迭代器时,你应该传递容器。

It's fairly simple, I guess you are passing iterators when you should be passing containers.

  std::string s = "fishing"; 
  std::cout << boost::algorithm::contains(s, "is") << std::endl; 
  std::vector<int> v {1,2,3,5,7,2,7,4,5,8};
  std::vector<int> v2 {5,7,2,7,4};
  std::vector<int> v3 {5,7,2,7,3};
  std::cout << boost::algorithm::contains(v, v2) << std::endl;
  std::cout << boost::algorithm::contains(v, v3) << std::endl;
