A good example for boost::algorithm::join
提问by Dan Hook
I recently wanted to use boost::algorithm::join but I couldn't find any usage examples and I didn't want to invest a lot of time learning the Boost Range library just to use this one function.
我最近想使用boost::algorithm::join但我找不到任何使用示例，而且我不想为了使用这个函数而花费大量时间学习 Boost Range 库。
Can anyone provide a good example of how to use join on a container of strings? Thanks.

#include <boost/algorithm/string/join.hpp>
#include <vector>
#include <iostream>
int main()
{
std::vector<std::string> list;
list.push_back("Hello");
list.push_back("World!");
std::string joined = boost::algorithm::join(list, ", ");
std::cout << joined << std::endl;
}
Output:
输出：
Hello, World!

std::vector<std::string> MyStrings;
MyStrings.push_back("Hello");
MyStrings.push_back("World");
std::string result = boost::algorithm::join(MyStrings, ",");
std::cout << result; // prints "Hello,World"
