cpp_array

Standard array implemented with all constexpr implementations from up to C++20.

This library implements the class std::array in its entirety as is documented on cppreference.com.

The only feature that this library does not implement is constexpr for swap.

This class is placed inside namespace ed.

Compiler support

This library compiles under following compilers:

GCC 5.1 or newer

• Until version 5.5, you need to provide -std=c++14 flag
• Versions 6.1 and newer do not require any language specific flags

Clang 3.5 or newer

• Until version 6.0.0, you need to provide -std=c++14 flag
• Newer versions do not need to provide any language specific flags

Visual Studio 2017

• Supported from version 19.10(Editor version 15.1) until 19.16(Editor version 15.9.4)
• All future versions of the IDE/compiler are expected to be supported, considering this library doesn't leverage any compiler-specific behaviour
• No need to provide any language specific flags for any compiler version

Example

#include "Array.hpp"

constexpr auto getArr() {
    ed::array<int, 10> ar{};
    ed::array ar2{ 5, 2, 3, 4, 5, 9, 7, 4, 8, 7 };  //Deduction guides, C++17
    auto res = ar < ar2 || ar == ar2;
    ar.fill(55);
    ar[4] = 81 + (res ? 3 : 0);
    return ar;
}

constexpr auto ar = getArr();

#include <iostream>

int main() {
    auto v1 = ar[4];
    auto v2 = ar[6];
    std::cout << v1 << " ";
    std::cout << v2 << "\n";
}

Output:
