std::ios_base::flags(3) C++ Standard Libary std::ios_base::flags(3) NAME std::ios_base::flags - std::ios_base::flags Synopsis fmtflags flags() const; (1) fmtflags flags( fmtflags flags ); (2) Manages format flags. 1) returns current formatting setting 2) replaces current settings with given ones. Parameters new formatting setting. It can be a combination of the fol- lowing constants: Constant Explanation dec use decimal base for integer I/O: see std::dec oct use octal base for integer I/O: see std::oct hex use hexadecimal base for integer I/O: see std::hex basefield dec|oct|hex. Useful for masking operations left left adjustment (adds fill characters to the right): see std::left right right adjustment (adds fill characters to the left): see std::right internal internal adjustment (adds fill characters to the internal designated point): see std::internal adjustfield left|right|internal. Useful for masking opera- tions scientific generate floating point types using scientific notation, or hex notation if combined with fixed: see std::scien- tific flags - fixed generate floating point types using fixed nota- tion, or hex notation if combined with scientific: see std::fixed floatfield scientific|fixed. Useful for masking operations boolalpha insert and extract bool type in alphanumeric format: see std::boolalpha generate a prefix indicating the numeric base for integer showbase output, require the currency indicator in mone- tary I/O: see std::showbase showpoint generate a decimal-point character uncondition- ally for floating-point number output: see std::showpoint showpos generate a + character for non-negative numeric output: see std::showpos skipws skip leading whitespace before certain input op- erations: see std::skipws unitbuf flush the output after each output operation: see std::unitbuf uppercase replace certain lowercase letters with their up- percase equivalents in certain output operations: see std::uppercase Return value the formatting flags before the call to the function Example This section is incomplete Reason: no example See also setf sets specific format flag (public member function) unsetf clears specific format flag (public member function) http://cppreference.com 2022.07.31 std::ios_base::flags(3)
