The Microsoft C++ 32-bit and 64-bit compilers recognize the types in the table later in this article.
Microsoft C++ 32 位和 64 位编译器可识别本文后面的表中的类型。

int (unsigned int)
__int8 (unsigned __int8)
__int16 (unsigned __int16)
__int32 (unsigned __int32)
__int64 (unsigned __int64)
short (unsigned short)
long (unsigned long)
long long (unsigned long long)

If its name begins with two underscores (__), a data type is non-standard.
如果其名称以两个下划线 (__) 开始，则数据类型是非标准的。

The ranges that are specified in the following table are inclusive-inclusive.
下表中指定的范围均包含起始值和结束值。

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.
根据使用方式，变量 __wchar_t 指定宽字符类型或多字节字符类型。在字符或字符串常量之前使用 L 前缀来指定宽字符类型的常量。

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.
signed and unsigned 是可以与除 bool 以外的任何整数类型一起使用的修饰符。请注意，就重载和模板等机制而言，char, signed char, and unsigned char 是三种不同的类型。

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.
int and unsigned int 类型具有四个字节的大小。但是，可移植代码不应依赖于 int 的大小，因为语言标准允许它是特定于实现的。

C/C++ in Visual Studio also supports sized integer types. For more information, see __int8, __int16, __int32, __int64 and Integer Limits.
Visual Studio 中的 C/C++ 还支持按大小分类的整型。有关详细信息，请参阅 __int8, __int16, __int32, __int64 和整数限制。

For more information about the restrictions of the sizes of each type, see Built-in types.
有关每种类型的大小限制的详细信息，请参阅内置类型。

The range of enumerated types varies depending on the language context and specified compiler flags. For more information, see C Enumeration Declarations and Enumerations.
枚举类型的范围因语言上下文和指定的编译器标志而异。有关详细信息，请参阅 C 枚举声明和枚举。
