Strings & Text
8 pages — std::string, string_view, format, print, conversions, and regex.
Test character properties and convert between uppercase and lowercase using standard library functions.
Header <cstring> provides null-terminated C-style string functions: strlen, strcpy, strcat, strcmp, and memory operations for interop with C code.
Deep dive into std::regex_iterator, regex_token_iterator, regex_replace, capture groups, and regex grammar flags introduced in C++11.
C++20 std::format and C++23 std::print — type-safe formatted output with compile-time checking, custom formatters, and efficient direct printing.
"The C++ standard string class — mutable, owning character sequences with construction, modification, searching, and conversions. Zero-copy alternatives: std::string_view."
Non-owning view of a character sequence. Zero-copy alternative to const std::string&. Accepts literals, std::string, and char arrays without allocation.
C++ string conversions — to_string, stoi/stof, from_chars, to_chars, and std::format with C++ version discipline and performance trade-offs.
Character and string types for wide character sets, including wchar_t, std::wstring, and Unicode-aware character types for international text.
