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.
2) Returns the weekday value stored in *this, except that Sunday (stored as

interpreted as 7 according to ISO 8601.

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';
}
}
