std::basic_string<CharT,Traits,Allocator>::ends_with
From cppreference.com
constexpr bool ends_with( std::basic_string_view<CharT, Traits> 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 ends with the given suffix. The suffix may be one of the following:
1) A string view
sv (which may be a result of implicit conversion from another std::basic_string).2) A single character
ch.3) A null-terminated character string
s.All three overloads effectively return std::basic_string_view<CharT, Traits>(data(), size()).ends_with(x), where x is the parameter.
Parameters
| sv | - | a string view which may be a result of implicit conversion from another std::basic_string
|
| ch | - | a single character |
| s | - | a null-terminated character string |
Return value
true if the string ends with the provided suffix, false otherwise.

Example
Run this code
#include <cassert>
#include <string>
#include <string_view>
int main()
{
using namespace std::literals;
const auto str = "Hello, C++20!"s;
assert
(""
&& str.ends_with("C++20!"sv) // (1)
&& !str.ends_with("c++20!"sv) // (1)
&& str.ends_with("C++20!"s) // (1) implicit conversion string to string_view
&& !str.ends_with("c++20!"s) // (1) implicit conversion string to string_view
&& str.ends_with('!') // (2)
&& !str.ends_with('?') // (2)
&& str.ends_with("C++20!") // (3)
&& !str.ends_with("c++20!") // (3)
);
