使用这个函数:

inline bool ends_with(std::string const & value, std::string const & ending)
{
    if (ending.size() > value.size()) return false;
    return std::equal(ending.rbegin(), ending.rend(), value.rbegin());
}

使用boost::algorithm::ends_with(参见http://www.boost.org/doc/libs/1_34_0/doc/html/boost/algorithm/ends_with.html):

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

// works with const char* 
assert(boost::algorithm::ends_with("mystring", "ing"));

// also works with std::string
std::string haystack("mystring");
std::string needle("ing");
assert(boost::algorithm::ends_with(haystack, needle));

std::string haystack2("ng");
assert(! boost::algorithm::ends_with(haystack2, needle));

使用std::string::compare:比较最后n个字符:

#include <iostream>

bool hasEnding (std::string const &fullString, std::string const &ending) {
    if (fullString.length() >= ending.length()) {
        return (0 == fullString.compare (fullString.length() - ending.length(), ending.length(), ending));
    } else {
        return false;
    }
}

int main () {
    std::string test1 = "binary";
    std::string test2 = "unary";
    std::string test3 = "tertiary";
    std::string test4 = "ry";
    std::string ending = "nary";

    std::cout << hasEnding (test1, ending) << std::endl;
    std::cout << hasEnding (test2, ending) << std::endl;
    std::cout << hasEnding (test3, ending) << std::endl;
    std::cout << hasEnding (test4, ending) << std::endl;

    return 0;
}

和上面一样，这是我的解

 template<typename TString>
  inline bool starts_with(const TString& str, const TString& start) {
    if (start.size() > str.size()) return false;
    return str.compare(0, start.size(), start) == 0;
  }
  template<typename TString>
  inline bool ends_with(const TString& str, const TString& end) {
    if (end.size() > str.size()) return false;
    return std::equal(end.rbegin(), end.rend(), str.rbegin());
  }

找到了类似的"startWith"问题的好答案:

如何检查一个c++ std::string是否以某个字符串开始，并将子字符串转换为int?

你可以采用只搜索字符串的最后一个位置的解决方案:

bool endsWith(const std::string& stack, const std::string& needle) {
    return stack.find(needle, stack.size() - needle.size()) != std::string::npos;
}

这样你可以使它短小、快速、使用标准c++并使其可读。

我的观点是:

bool endsWith(std::string str, std::string suffix)
{
   return str.find(suffix, str.size() - suffix.size()) != string::npos;
}
