std::source...ion::column(3)   C++ Standard Libary  std::source...ion::column(3)

NAME
     std::source_location::column - std::source_location::column

Synopsis
	constexpr std::uint_least32_t column() const noexcept;	(since C++20)

	Returns  an  implementation-defined  value representing some offset from
     the start of
	the line represented by this object (i.e., the	column	number).  Column
     numbers are
	presumed to be 1-indexed.

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).

	An implementation is encouraged to use 0 when the column number  is  un-
     known.

Example
     // Run this code

      #include <iostream>
      #include <source_location>

      template<typename T = std::source_location>
      inline void pos(const T& location = T::current())
      {
	  std::cout
	      << "("
	      << location.line()
	      << ':'
	      << location.column()
	      << ") ";
      }

      int main()
      {
      //      a: column #9
	  pos(); std::cout << "Proxima\n";    // row #18
	    pos(); std::cout << "Centauri\n"; // row #19
      //	a: column #11
      }

Possible output:
      (18:9) Proxima
      (19:11) Centauri
