std::basic_string_view<CharT,Traits>::ends_with - cppreference.com

constexpr bool ends_with( basic_string_view sv ) const noexcept;

(1) (since C++20)

constexpr bool ends_with( CharT ch ) const noexcept;

(2) (since C++20)

constexpr bool ends_with( const CharT* s ) const;

(3) (since C++20)

Checks if the string view ends with the given suffix, where

1) the suffix is a string view. Effectively returns size() >= sv.size() && compare(size() - sv.size(), npos, sv) == 0.

2) the suffix is a single character. Effectively returns !empty() && Traits::eq(back(), ch).

3) the suffix is a null-terminated character string. Effectively returns ends_with(basic_string_view(s)).

[edit] Parameters sv - a string view which may be a result of implicit conversion from std::basic_string ch - a single character s - a null-terminated character string [edit] Return value

true if the string view ends with the provided suffix, false otherwise.

[edit] Notes [edit] Example

#include <cassert>
#include <string_view>
 
int main()
{
    using namespace std::literals;
 
    assert
    (""
        // (1) ends_with( basic_string_view sv )
        && std::string_view("https://cppreference.com").ends_with(".com"sv) == true
        && std::string_view("https://cppreference.com").ends_with(".org"sv) == false
 
        // (2) ends_with( CharT c )
        && std::string_view("C++20").ends_with('0') == true
        && std::string_view("C++20").ends_with('3') == false
 
        // (3) ends_with( const CharT* s )
        && std::string_view("string_view").ends_with("view") == true
        && std::string_view("string_view").ends_with("View") == false
    );
}
