u16 wchar_t 2 __wchar_t 0 to 65,535

  • Depending on how it's used, a variable of __wchar_t designates either a wide-character type or multibyte-character type. Use the L prefix before a character or string constant to designate the wide-character-type constant.

  • signed and unsigned are modifiers that you can use with any integral type except bool. Note that char, signed char, and unsigned char are three distinct types for the purposes of mechanisms like overloading and templates.

  • The int and unsigned int types have a size of four bytes. However, portable code should not depend on the size of int because the language standard allows this to be implementation-specific.

  • C/C++ in Visual Studio also supports sized integer types. For more information, see __int8, __int16, __int32, __int64 and Integer Limits.

  • For more information about the restrictions of the sizes of each type, see Built-in types.

  • The range of enumerated types varies depending on the language context and specified compiler flags. For more information, see C Enumeration Declarations and Enumerations.

Compilers[🔝]

Use every available and reasonable set of warning options. Some warning options only work with optimizations enabled, or work better the higher the chosen level of optimization is, for example -Wnull-dereference with GCC.

You should use as many compilers as you can for your platform(s). Each compiler implements the standard slightly differently and supporting multiple will help ensure the most portable, most reliable code.

GCC / Clang[🔝]

-Wall -Wextra -Wshadow -Wnon-virtual-dtor -pedantic

  • use these and consider the following (see descriptions below)

see descriptions below

  • -pedantic - Warn on language extensions

  • -Wall -Wextra reasonable and standard

  • -Wshadow warn the user if a variable declaration shadows one from a parent context

  • -Wnon-virtual-dtor warn the user if a class with virtual functions has a non-virtual destructor. This helps catch hard to track down memory errors

  • -Wold-style-cast warn for c-style casts

  • -Wcast-align warn for potential performance problem casts -Wunused warn on anything being unused

  • -Woverloaded-virtual warn if you overload (not override) a virtual function

  • -Wpedantic (all versions of GCC, Clang >= 3.2) warn if non-standard C++ is used

  • -Wconversion warn on type conversions that may lose data

  • -Wsign-conversion (Clang all versions, GCC >= 4.3) warn on sign conversions

  • -Wmisleading-indentation (only in GCC >= 6.0) warn if indentation implies blocks where blocks do not exist

  • -Wduplicated-cond (only in GCC >= 6.0) warn if if / else chain has duplicated conditions

  • -Wduplicated-branches (only in GCC >= 7.0) warn if if / else branches have duplicated code

  • -Wlogical-op (only in GCC) warn about logical operations being used where bitwise were probably wanted

  • -Wnull-dereference (only in GCC >= 6.0) warn if a null dereference is detected

  • -Wuseless-cast (only in GCC >= 4.8) warn if you perform a cast to the same type

  • -Wdouble-promotion (GCC >= 4.6, Clang >= 3.8) warn if float is implicitly promoted to double

  • -Wformat=2 warn on security issues around functions that format output (i.e., printf)

  • -Wlifetime (only special branch of Clang currently) shows object lifetime issues

  • -Wimplicit-fallthrough Warns when case statements fall-through. (Included with -Wextra in GCC, not in clang)

Consider using -Weverything and disabling the few warnings you need to on Clang

  • -Weffc++ warning mode can be too noisy, but if it works for your project, use it also.

- Visual C++ CRT 오류 -

  1. VS에서 scanf, strcpy를 썼을 때 오류가 난다면 맨 위에 #define _CRT_SECURE_NO_WARNINGS를 붙여주세요.

  2. #define _CRT_SECURE_NO_WARNINGS는 #include보다 위에 놓아야 합니다.

  3. scanf_s에서 %c 또는 %s를 쓸 땐 주소가 가리키는 영역에 할당된 크기를 추가로 넣어야 합니다. 예) scanf_s("%s %c", &s, sizeof s, &c, sizeof c);
