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
#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 6 6 6 Sat 7 0 7 Sun
