Brief history of self-modified code Self-modified code has a wide range of uses: 1. It was very difficult to use SMC (self-protection code) to protect applications 10 to 20 years ago, even if it was used to put compiled code into the memory. 2. the

C ++ starts from scratch (2) -- What is an expression? This is the beginning of this series. When learning English, the first thing to learn is letters, which is the basis of English. Similarly, in C ++, all code is composed of identifier,

Sha isData EncryptionAlgorithmThis algorithm has been developed and improved by encryption experts over the years and has become one of the most secure and widely used Hash algorithms. The idea of this algorithm is to receive a piece of plain text,

Bitwise AND operator (&) The two data involved in the operation perform the "and" Operation in binary bits. Calculation rule: 0 & 0 = 0; 0 & 1 = 0;  1 & 0 = 0;   1 & 1 = 1;       That is, if the two digits are "1" at the same time, the result

The data is merged through id2d1geometry. combinewithgeometry (), but id2d1simplifiedgeometrysink (parent object of id2d1geometrysink) is returned ); You need to add id2d1simplifiedgeometrysink to id2d1pathgeometry for use. Uses direct2d, d2d1;

Operation Change operations: 0 a B change all characters into '0's in [a, B] 1 a B change all characters into '1' s in [a, B]2 a B change all '0' s into '1' S and change all '1' s into '0' s in [a, B] Output operations:3 a B output the number of '1

Question: The minimum integer in an array that is at least startno and does not exist in an unordered integer. For example, the minimum integer not less than 3 in, is 3.   The following test code shows that the implementation is not

Bitwise operations are binary operations. In system software, binary bitwise is often required. The C language provides six operations Operator. These operators can only be used for integer operands, that is, they can only be used for signed or

Question: Read 10000000 (10 ^ 7) unsigned 32-bit integers and take one from them. The remaining 9999999 integers. Find out which one is taken. Requirements: The code can contain up to four unsigned 32-bit integer variables.   Solution: The XOR

Key words: CRC algorithm principle; CRC verification; modulo 2 (mod 2); mod 2The CRC verification algorithm adopts a binary algorithm called "modulo 2 operation. The modulo 2 operation is the core part of the CRC operation. Therefore, before

The setxormode (true) method is used to make the target color the result value of the XOR operation of the source and target colors. When the parameter is false, the difference or effect of the drawing is canceled. Before using setxormode, you

Mode operation After the reset response, the card is in one of the following two operation modes: --If TA (2) exists, it is in a specific mode; --If TA (2) does not exist, it is in the negotiation mode. The figure shows how to select and switch the

Abstract:Many companies often add their logo to the QR code for commercial purposes. However, if the logo block area is large enough, the QR code Becomes unrecognizable. Is there a way to "empty" the above area in advance (to specifically place the

In an array of integers, except for two digits, the other numbers appear two times. Please write the program to find the two only occurrences of the number.The number appears two times, then the XOR or affirmation is 0.Consider the simplified

Design and simulation verification of integer multiplier based on Verilog HDL1. Pre-KnowledgeIntegers are divided into short integers, medium integers, long integers, and only short integers are involved in this article. Short integer: Occupies a

The implementation of the custom encryption algorithm requires a secret ID, so symmetric encryption is used. However, the string encrypted by the mcrypt_encrypt algorithm is too long. therefore, to implement a custom encryption algorithm, the idea

Recently made a vote, need to do anti-brush ticket measures. But it is very difficult to avoid the ticket, after all, more means. In order to prevent the swipe ticket to the maximum extent, this method is used. First define a string ' www.bkjia.com
