c++返回一个pair类型

前言

Under the new standard we can list initialize the return value.

代码测试

#include<iostream>
#include<string>
#include<vector>

std::pair<std::string, int>
process(std::vector<std::string>& v)
{
	if (!v.empty())
	{
		return { v.back(), v.back().size() }; // list initialize返回
	}
	else
	{
		return std::pair<std::string, int>();
	}
}

int main()
{
	std::vector<std::string> vecT{ "hablee","yuki" };
	std::pair<std::string, int> re = process(vecT);
	std::cout << re.first << ", " << re.second << std::endl;

	return 0;
}
