# std::basic_string<CharT,Traits,Allocator>::starts_with

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; | (2) | (since C++20)
bool starts_with(const CharT* x) const; | (3) | (since C++20)

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.
