NAME

std::chrono::weekday::c_encoding,std::chrono::weekday::iso_encoding - std::chrono::weekday::c_encoding,std::chrono::weekday::iso_encoding

Synopsis

constexpr unsigned c_encoding() const noexcept; (1) (since C++20)
constexpr unsigned iso_encoding() const noexcept; (2) (since C++20)

1) Returns the weekday value stored in *this.
1) Returns the weekday value stored in *this, except that Sunday (stored as 0)
is interpreted as 7 according to ISO 8601.

Return value

1) The weekday value stored in *this.
2) c_encoding() == 0u ? 7u : c_encoding().

Example

// Run this code

#include <chrono>
#include <iostream>

int main()
{
std::cout << "i: C: ISO: Weekday:\n";

for (unsigned i{0}; i != 8; ++i) {
const std::chrono::weekday w{i};
std::cout << i << " "
<< w.c_encoding() << " "
<< w.iso_encoding() << " "
<< w << '\n';
}
}

Possible output:

i: C: ISO: Weekday:
0 0 7 Sun
1 1 1 Mon
2 2 2 Tue
3 3 3 Wed
4 4 4 Thu
5 5 5 Fri
