unsigned int类型可以简写为unsigned,也就是说,unsigned后不加其他类型说明符就意味着是unsigned int。 一字节表示八位,即:1byte = 8 bit; int: 4byte = 32 bit 有符号signed范围:2^31-1 ~ -2^31即:2147483647 ~ -2147483648无符号unsigned范围:2^32-1 ~ 0即:4294967295 ~ 0 long: 4 byte = 32 bit...
原因是早期的C编译器定义了long int占用4个字节,int占用2个字节,long int是名副其实的长整型。在ANSI C的标准中,对长整型的定义也是long int应该至少和int一样长,而不是long int 一定要比int占用存储字节长。所以,正确的关系应该是—— l o n g ≥ i n t ≥ s h o r t long\geq int\geq short ...
在计算机编程中，long 和 int 都是整数类型，用于存储整数值。它们之间的主要区别在于存储空间的大小和平台依赖性。存储空间大小：int：在大多数现代编程语言中，int 类型通常用于存储在内存中的整数值。其大小通常是32位（即4个字节），它可以存储的值的范围从 -2,147,483,648 到 2,147,483,647（...
此外，`int`不能比`short`大，`long`不能比`int`大。在大多数电脑操作系统中，如Windows和Mac OS，...

将类型为 INT8 的值转换为 ULONGLONG 类型的值。语法cpp 复制 HRESULT Int8ToULongLong( [in] INT8 i8Operand, [out] ULONGLONG *pullResult ); 参数[in] i8Operand要转换的值。[out] pullResult转换后的值。返回值如果此函数成功,则返回 S_OK。 否则,将返回 HRESULT 错误代码。
