Types fenv_t The type representing the entire floating-point environment fexcept_t The type representing all floating-point status flags collectively Functions feclearexcept (C++11) clears the specified floating-point status flags (function) fetestexcept (C++11) determines which of the specified floating-point status flags are set (f

Usage char16_t type: as the declaration of the type (since C++11)

This header was originally in the C standard library as <float.h>. This header is part of the type support library, in particular it's part of the C numeric limits interface. Macros FLT_RADIX the radix (integer base) used by the representation of all three floating-point types (macro constant) DECIMAL_DIG (C++11) number of decimal digits that can be converted to long double and back without losing precision (macro constant) FLT_MINDBL_MINLDBL_MIN minimum value of float, do

Usage try-catch block

Usage switch statement: as the declaration of the case labels

This header was originally in the C standard library as <ctype.h>. This header is part of the null-terminated byte strings library. Functions isalnum checks if a character is alphanumeric (function) isalpha checks if a character is alphabetic (function) islower checks if a character is lowercase (function) isupper checks if a character is an uppercase character (function) isdigit checks if a character is a digit (function) isxdigit checks if a character i

This header was originally in the C standard library as <assert.h>. This header is part of the error handling library. Macros assert aborts the program if the user-specified condition is not true. May be disabled for release builds (function macro)

This header was originally in the C standard library as <complex.h>. Includes <complex>

A Callable type is a type, for which the INVOKE operation, as defined by std::function, std::bind, or std::thread::thread is applicable. This operation may be performed explicitly using the library function std::invoke. (since C++17). Requirements The type T satisfies Callable if. Given. f, an object of type T or const T ArgTypes, suitable list of argument types R, suitable return type The following expressions must be valid: Expression Requirements INVOKE(f, std::declval<ArgTyp

The C I/O subset of the C++ standard library implements C-style stream input/output operations. The <cstdio> header provides generic file operation support and supplies functions with narrow and multibyte character input/output capabilities, and the <cwchar> header provides functions with wide character input/output capabilities. C streams are objects of type std::FILE that can only be accessed and manipulated through pointers of type std::FILE* (Note: while it may be possible to cr
