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.

[edit] 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

[edit] Return value

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

[edit] Example

#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)
    );
}
