所以我有一个lambda，其返回类型为 <?php
$page_number = $_GET['page'];
$dbdit = new PDO('mysql:host=localhost;dbname=laundry','root','');
$results = $dbdit->prepare("SELECT COUNT(*) FROM konsumen");
$results->execute();
$get_total_rows = $results->fetch();
$results = $dbdit->prepare("SELECT * FROM konsumen ORDER BY kode_pemesanan ASC LIMIT $page_number");
$resultkaryawan = $dbdit->prepare("SELECT * FROM karyawan");
$results->execute();
$resultkaryawan->execute();
$row = $results->fetch();
while($data = $resultkaryawan->fetch()){
print_r("<table align='center' >

，我遇到了auto在此处被销毁的阵列支持问题：
initializer_list我会像这样使用lambda：
const auto foo = [](const auto& a, const auto& b, const auto& c) { return {a, b, c}; };
我正在工作的工作是他们的编码标准的一部分，所有lambda都是单一陈述（随意表达你的愤慨。）我认为我可以解决这个问题：
auto bar = foo(1, 2, 3);
for(const auto& i : bar) cout << i << endl;
一个foo的返回类型，但这会弄乱它的通用性：vector int const auto foo = [](const auto& a, const auto& b, const auto& c) -> vector<int> { return {a, b, c}; }的模板化函数并将其返回：vector<T> 是否有可能将这些变量强制转换为一个容器，谁的支持不会在一行中被销毁，这样我就能保持lambda的template <typename T> vector<T> foo(const T& a, const T& b, const T& c){ return {a, b, c}; }返回类型？
答案 0 :(得分：3)
库基础知识TS v2有std::experimental::make_array，这肯定会满足您的要求：
#include <experimental/array>
const auto foo = [](const auto& a, const auto& b, const auto& c) {
return std::experimental::make_array(a, b, c); };
更一般地说，template argument deduction for constructors允许你写：
const auto foo = [](const auto& a, const auto& b, const auto& c) {
return std::vector{a, b, c}; };
^-- no template parameter required
今天，您可以使用common_type：
const auto foo = [](const auto& a, const auto& b, const auto& c) {
return std::vector<std::common_type_t<decltype(a), decltype(b), decltype(c)>>{a, b, c}; };
