From cppreference.com
< cpp | string | basic string
bool starts_with(std::basic_string_view<CharT, Traits> x) const noexcept; |
(1) | (since C++20) |
bool starts_with(CharT x) const noexcept; |

Checks if the string begins with the given prefix, where
1) the prefix is a string view (which may be a result of implicit conversion from another
std::basic_string
)2) the prefix is a single character
3) the prefix is a C-style string
All three overloads effectively return std::basic_string_view<CharT, Traits>(data(), size()).starts_with(x);
Parameters
x | - | a character sequence or a single character to compare to the start of the string |
Return value
true if the string begins with the provided prefix, false otherwise.
