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 ...

Strings library - cppreference.com
String classes (std::string etc.) The class template std::basic_string generalizes how sequences of characters are manipulated and stored. String creation, manipulation, and destruction are all handled by a convenient set of class methods and related functions. Several specializations of std::basic_string are provided for commonly-used types:

std::basic_string_view - cppreference.com
The class template basic_string_view describes an object that can refer to a constant contiguous sequence of CharT with the first element of the sequence at position zero.. For a basic_string_view str, pointers, iterators, and references to elements of str are invalidated when an operation invalidates a pointer in the range [str. data (), str. data + str. size ()).

string - C++ Users
Strings are objects that represent sequences of characters. The standard string class provides support for such objects with an interface similar to that of a standard container of bytes, but adding features specifically designed to operate with strings of single-byte characters. The string class is an instantiation of the basic_string class template that uses char (i.e., bytes) as its ...

std::to_string - cppreference.com
Return value. A string holding the converted value. [] ExceptionMay throw std::bad_alloc from the std::string constructor. [] NoteWith floating point types std::to_string may yield unexpected results as the number of significant digits in the returned string can be zero, see the example.; The return value may differ significantly from what std::cout prints by default, see the example.

c++ - Converting an int to std::string - Stack Overflow
If you cannot use std::to_string from C++11, you can write it as it is defined on cppreference.com: std::string to_string( int value ) Converts a signed decimal integer to a string with the same content as what std::sprintf(buf, "%d", value) would produce for sufficiently large buf. Implementation

Strings library - cppreference.com - man6.org
The C++ strings library includes support for three general types of strings: std::basic_string - a templated class designed to manipulate strings of any character type.; std::basic_string_view (C++17) - a lightweight non-owning read-only view into a subsequence of a string.; Null-terminated strings - arrays of characters terminated by a special null character.

std::basic_string<CharT,Traits,Allocator>:: find - Reference
std:: basic_string_view < CharT, Traits >> is true and std:: is_convertible_v < const StringViewLike &, const CharT * > is false. Formally, a substring str is said to be found at position xpos if all of the following are true :
