2012年3月14日 · int is a primitive type allowed by the C# compiler, whereas Int32 is the Framework Class Library type (available across languages that abide by CLS). In fact, int translates to Int32 during compilation. Also, In C#, long maps to System.Int64, but in a different programming language, long could map to Int16 or Int32.

The int and unsigned int types have a size of 4 bytes. However, portable code shouldn't 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.

2018年12月4日 · 本文详细解析了int8_t、int16_t等跨平台整型数据类型，包括它们的定义、位数、字节数及取值范围，对比了size_t与ssize_t的用途，适合所有对跨平台编程感兴趣的开发者。

The minimum size for char is 8 bits, the minimum size for short and int is 16 bits, for long it is 32 bits and long long must contain at least 64 bits. The type int should be the integer type that the target processor is most efficiently working with.

2008年9月19日 · Simply use: Integer.MAX_VALUE in Java. 2,147,483,647 = 0x7FFFFFFF, if you wanna remember it, just use hex. The most correct answer I can think of is Int32.MaxValue. Before this existed, I used to #define INT32_MIN and INT32_MAX in all my projects. When you are programming: yes in 99% of cases.

2023年6月19日 · 使用 size_t 来代替 int 或 unsigned 可以保证在同一个平台中，始终得到得到一个数据类型或变量的字节大小，保证了程序对该数据类型或变量的统计方式始终一致，不会因为平台的改变而出现错误。

inttypes.h 是 C 标准库中一个非常重要的头文件，它提供了一组固定宽度的整数类型和相应的格式化宏，通过使用这些类型和宏，开发者可以确保在不同平台上，整数的大小和格式化输出是一致的，从而避免潜在的问题。 inttypes.h 定义了一组固定宽度的整数类型，这些类型在不同的平台上具有相同的大小。 以下是常见的固定宽度整数类型： 这些类型确保了在不同平台上，整数的大小是一致的，从而提高了代码的可移植性。 inttypes.h 还定义了一组格式化宏，用于在 printf 和 …

2021年8月2日 · Microsoft C/C++ features support for sized integer types. You can declare 8-, 16-, 32-, or 64-bit integer variables by using the __intN type specifier, where N is 8, 16, 32, or 64. The following example declares one variable for each of these types of sized integers:

2013年1月25日 · Where int8_t and int32_t each have a specified size, int can be any size >= 16 bits. At different times, both 16 bits and 32 bits have been reasonably common (and for a 64-bit implementation, it should probably be 64 bits). On the other hand, int is guaranteed to be present in every implementation of C, where int8_t and int32_t are not. It's ...

2013年6月5日 · size_t ： unsigned signed size of computer word size。 它们也是表示计算机的字长，在32位机器上是int型，在64位机器上long型，从某种意义上来说它们等同于intptr_t和 uintptr_t。 它们在stddef.h里面定义。 #endif /* Unsigned. */ . #endif #if __WORDSIZE == 64 . #else . #endif. /* Minimum of signed integral types. */ . /* Maximum of signed integral types. */ . /* Maximum of unsigned integral types. */ .
