Strings

This header introduces string types, character traits and a set of converting functions:

Class templates

basic_string: Generic string class (class template)

char_traits: Character traits (class template)

Class instantiations

string: String class (class)

u16string: String of 16-bit characters (class)

u32string: String of 32-bit characters (class)

wstring: Wide string (class)

Functions

Convert from strings

stoi: Convert string to integer (function template)

stol: Convert string to long int (function template)

stoul: Convert string to unsigned integer (function template)

stoll: Convert string to long long (function template)

stoull: Convert string to unsigned long long (function template)

stof: Convert string to float (function template)

stod: Convert string to double (function template)

stold: Convert string to long double (function template)

Convert to strings

to_string: Convert numerical value to string (function)

to_wstring: Convert numerical value to wide string (function)

Range access
