std::basic_...emove_suffix(3) C++ Standard Libarystd::basic_...emove_suffix(3)

NAME
       std::basic_string_view::remove_suffix   -   std::basic_string_view::re-
       move_suffix

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
