Checks if the string ends with the given suffix. The suffix may be one of the following:
std::basic_string
).All three overloads effectively returnstd::basic_string_view<CharT, Traits>(data(), size()).ends_with(x), wherex
is the parameter.
Contents |
sv | - | a string view which may be a result of implicit conversion from anotherstd::basic_string |
ch | - | a single character |
s | - | a null-terminated character string |
true if the string ends with the provided suffix,false otherwise.
