std::ios_base::flags(3)

💅 std::ios_base::flags(3) 💅

Okay so we're flipping through the C++ Standard Libary manual, section 3, and this page is the std::ios_base::flags glow-up. It's giving format flag headquarters energy, and honestly? iconic. ✨

🦋 NAME 🦋

std::ios_base::flags — that's the function name, bestie. Literally std::ios_base::flags. No cap. 💖

🌸 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 🍓

• flags — new formatting setting. It can be a combination of formatting flags constants.

✨ Formatting flags ✨

• 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 operations
• scientific — generate floating point types using scientific notation, or hex notation if combined with fixed: see std::scientific
• fixed — generate floating point types using fixed notation, 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
• showbase — generate a prefix indicating the numeric base for integer output, require the currency indicator in monetary I/O: see std::showbase
• showpoint — generate a decimal-point character unconditionally 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 operations: see std::skipws
• unitbuf — flush the output after each output operation: see std::unitbuf
• uppercase — replace certain lowercase letters with their uppercase equivalents in certain output operations: see std::uppercase

👑 Return value 👑

It hands back the formatting flags before the call to the function. So you get the old vibe check result, basically. 💅
