Questions tagged [string-literals]

C and C++ have several ways to represent strings in code. They include the basic double quoted "Hello, World!". Strings can be concatenated "as" " follows". C++-0X has added new encodings u"Hello" for UTF16 (char16_t), U"world" for UTF32 (char32_t) is addition to L"long" for wchar_t. There are rules for concatenating different encodings.
