# std::basic_string_view<CharT,Traits>::ends_with

From cppreference.com
< cpp‎ | string‎ | basic string view

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)).

### 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

### Return value

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

### Example

Run this code

    #include <iostream>
    #include <string_view>

    int main()
    {
        using namespace std::literals;

        std::cout
            << std::boolalpha

            // (1) bool ends_with( basic_string_view sv ) const noexcept;
            << std::string_view("https://cppreference.com").ends_with(".com"sv) << ' ' // true
            << std::string_view("https://cppreference.com").ends_with(".org"sv) << ' ' // false

            // (2) bool ends_with( CharT c ) const noexcept;
            << std::string_view("C++20").ends_with('0') << ' ' // true
            << std::string_view("C++20").ends_with('3') << ' ' // false

            // (3) bool ends_with( const CharT* s ) const;
            << std::string_view("string_view").ends_with("view") << ' '   // true
            << std::string_view("string_view").ends_with("View") << '\n'; // false
    }

Output:

    true false true false true false
