std::basic_string - cppreference.com

The class template basic_string stores and manipulates sequences of character-like objects, which are non-array objects of TrivialType and StandardLayoutType.The class is dependent neither on the character type nor on the nature of operations on that type. The definitions of the operations are supplied via the Traits template parameter - a specialization of std::char_traits or a compatible ...

std::string class in C++ - GeeksforGeeks

As strings are represented as objects, no array decay occurs. There is a threat of array decay in the case of the character array. Strings are slower when compared to implementation than character array. Implementation of character array is faster than std:: string. String class defines a number of functionalities that allow manifold operations ...

Compares the contents of a string with another string or a null-terminated array of CharT.. All comparisons are done via the compare() member function (which itself is defined in terms of Traits::compare()): . Two strings are equal if both the size of lhs and rhs are equal and each character in lhs has equivalent character in rhs at the same position.
