constexpr std::uint_least32_t column() const noexcept;
(library fundamentals TS v2)

Returns an implementation-defined value representing some offset from the start of the line represented by this object (i.e., the column number).

Parameters

(none)

Return value

An implementation-defined value representing some offset from the start of the line represented by this object (i.e., the column number).

Example

#include <iostream>
#include <experimental/source_location>
 
template<typename T = std::experimental::source_location>
inline void pos(const T& location = T::current())
{
    std::cout
        << "("
        << location.line()
        << ':' 
        << location.column()
        << ") ";
}
 
auto main() -> int
{
    pos(); std::cout << "Proxima\n";
    pos(); std::cout << "Centauri\n";
}

Possible output:

(17:5) Proxima
(18:5) Centauri
