NAME
     std::basic_string_view::remove_suffix - std::basic_string_view::remove_suf-
     fix

Synopsis
	constexpr void remove_suffix( size_type n );  (since C++17)

	Moves the end of the view back by n characters.

	The behavior is undefined if n > size().

Parameters
	n - number of characters to remove from the end of the view

Return value
	(none)

Complexity
	Constant.

Example
     // Run this code

      #include <iostream>
      #include <string_view>

      int main()
      {
	  char arr[] = {'a', 'b', 'c', 'd', '\0', '\0', '\0'};
	  std::string_view v(arr, sizeof arr);
	  auto trim_pos = v.find('\0');
	  if (trim_pos != v.npos)
	      v.remove_suffix(v.size() - trim_pos);
	  std::cout << "Array: '" << arr << "', size=" << sizeof arr << '\n'
		    << "View : '" << v << "', size=" << v.size() << '\n';
      }

Output:
      Array: 'abcd', size=7
      View : 'abcd', size=4
