When the Linux kernel is transplanted between platforms with large differences in architecture, problems related to data types will occur. . Use the-wall-W strict-prototypes option when compiling the kernel to avoid many errors. The basic data types

This table is the data type supported by the visual C ++ 7.1 compiler, that is, the "root" of various data types in windows. Data Type name Bytes Alias Value Range Int * Signed, signed int

In the previous blog "read safearray data", we introduced C # To Read secure arrays. How can we compile com?1. Define the safearray variable SAFEARRAY *pSArray = NULL; 2. Release this variable SafeArrayDestroy(pSArray); 3. Create a vector

  # Include Struct s {Char CH, * PTR;Union {Short A, B;Unsigned int C: 2, D: 1;};Struct s * next;}; Int main (){Printf ("% d \ n", sizeof (struct s ));Return 1;} Answer: 16 1 byte ch 3bytes completion4 bytes PTR4 bytes Union4 bytes next--------------

3.3 Numeric data typesFrom the moment we open our eyes every morning, we deal with numbers almost every hour: from 6:30 on the alarm clock to the 216 bus to work, from the news that the house price fell to 100 yuan per square meter to go home to buy

The type of int is special, and the specific number of bytes is related to the machine word length and compiler. If you want to ensure the portability, try to use __int16 __int32 __int64.__int16, __int32 This data type allocates the same bytes under

The idea is that Ida F5 is really powerful, and will later use F5 to extract the code and record the ideas in the process of extracting the code.The first thing to note is that the local variables in the pseudo-code function generated by F5 are all 1

Reference: http://blog.csdn.net/vast_sea/article/details/8076934On this basic question, it is clear from a long time ago that the C standard does not specify the number of bytes that the basic type should be, and this is also related to the machine,

As a program developer, generally will not be limited to understand a language, with the understanding of language, often will be mixed, in order to facilitate memory, deliberately summed up the Java, PHP, C + + language data types, easy to compare,
