  1. Representation of the source code, reverse code, and complement code   (1) original code: directly add a sign before the value.   For example, the symbol bit value   [+ 7] original = 0 0000111 B   [-7] original = 1 0000111 B   Note: a. The

Many times we need to convert a byte array into a 16 binary string to save, such as when I am I/O byte stream operation, especially in a lot of encrypted scenes application is more extensive.In Java, Byte uses a binary representation of 8 bits, and

8 Basic data types of Java1 English letters, 1 digits, 1 symbols each in one byte; 1 Chinese characters account for two bytes; 1 bytes = 8 bitsNumeric type:A byte is 1 bytes. 8 bits, 0 or 1 on each bit. Value range: 128 ~ 127Short is 2 bytes. 16

Met the big end of data storage and small-ended problems, this your sister's confused, found that I have a serious lack of basic knowledge, ah, first understand the C + + data types on their own machine accounted for how many bytes, and these data

"Here we are going to discuss some advanced bit manipulation techniques that will greatly increase the speed of your program if used properly" We have discussed some simple bit manipulation methods, and if you are not familiar with bit operations

I ' m confused about unaligned memory accesses on ARM.My understanding was, they ' re isn't allowed-that is,Dereferencing a 32-bit value from a pointer this ' s not four-byte aligned would crash.I ' ve run into such crashes before.But right now I '

 In a computer system, all values are represented (stored) by supplementary codes ). The main reason is that the complement code can be used to process the symbol bit and other digits in a unified manner. At the same time, the subtraction can also

BOOL: Boolean value (Boolean value, TRUE or FALSE) BSTR: 32-bit character pointer BYTE: an 8-bit integer with no plus or minus signs COLORREF: 32-bit value, representing a color value DWORD: 32-bit integer without plus or minus signs LONG: 32-

Bool a Boolean value. BSTR a 32-bit character pointer. Byte an 8-bit integer that is not signed. Colorref a 32-bit value used as a color value. DWORD a 32-bit unsigned integer or the address of a segment and its associated offset. Long a 32-bit

For ix86 programming, sometimes it is necessary to change from the real mode to the protection mode (for example, to access extended memory in the DOS era, or to write pilot code, of course, if you program in a 32-bit operating system, you won't be

When talking about Operation permissions in Linux, three permissions (R, W, and X) are assigned to the corresponding three roles (owner, group member, and others, is 3*3 = 9. The records are recorded with 9 flag positions respectively. When LS-L is
