bitwise computers

The bitwise XOR operator (^) is a bitwise XOR on two expressions, and the following is an introduction to its specific useThe bitwise XOR operator (^) performs a bitwise XOR on two expressions. How to use: The code is as follows: result = expression1 ^ expression2 where result is any variable. Expression1 is any expres

router sends the data packet to other networks until the destination is reached. Determining whether different hosts are in the same network is the network ID corresponding to the Host IP address. The network ID length determines the IP address type. As long as the network ID length is the same, it belongs to the same type of network. In this way, only one network can exist in one network segment, because their network subnet mask is the same. The network ID includes the network ID and subnet I

(Reprint statement:Source: http://blog.csdn.net/vebasan/article/details/6193916Vebasan）The bitwise operator is primarily for binary, and it includes: "and", "Non", "or", "XOR". On the surface it seems a bit like a logical operator, but the logical operator is a logical operation on two relational operators, while the bitwise operator is mainly for the bits of two binary numbers. Each bit operator is describ

bit operations in Boolean algebra. Bit operations are the most common way we use masks. For example, we know an integer x, and if we want to get the integer value of the last byte of this integer, we can take a bitwise operation. Just like this.#include int main () { int0x12345678; int 0xFF ; int k = i j; printf ("%x\n", k);}Eventually we want the result to be 78, which is the value of the last byte of the integer I, and we use a

The bitwise operator is primarily for binary, and it includes: "and", "Non", "or", "XOR". On the surface it seems a bit like a logical operator, but the logical operator is a logical operation on two relational operators, while the bitwise operator is mainly for the bits of two binary numbers. Each bit operator is described in detail below.1. With operatorAnd the operator is denoted by the symbol "", which

1. Boolean operators logic and;|| logical OR;! = does not equal;Ternary operator:?:; expression is condition? Expression1:expression2 (returns the value of expression1 when the condition is true, otherwise returns the value of expression2); "and" and | | " Or "are evaluated in a short-circuit manner, so the first operation can determine the value of an expression without calculating the second operation.For example: x!=01/x>x+y//Avoid infinite error when x=0;2.

Bitwise operation Bitwise operations in C include bitwise operations (), (|), (^), and non (~). The following code package expands these basic operations, and there is also a two-digit Exchange (not a third number ). #include Logical operation Logical operations include || ,,!, Corresponds to the OR, and, not. There are only two types of logical operations: t

Today, when I read the tree array, I suddenly found this thing and thought about it. Then I briefly proved it with text: 2^k = L and (L xor (L　－　１) ) Set the first K-bit of I from the end of the binary value not to 0. first use C = I ^ (I-1), then the K to the left number to 0, from K to the right are 1 and then I C because the end of C K is 1, K to left 0, I at the end of the k-1 is 0, K is 1, K to left do not know. After bitwise AND, the remainin

single-digit domains. (Note that the value assignment cannot exceed the permitted range of the bit field) The program outputs the content of the three fields in integer format in line 1. Row 3 sends the bit address of the bit field variable to the pointer variable pbit. Row 14th re-assigns a value to bit field A as a pointer and assigns it to 0. Row 15th uses the compound bitwise operator " =", which is equivalent to 7 in the original value of pbit->

Back to directory In this article, "2" refers to binary, that is, when we see 2, it is also called every two, and it is the simplest and clearest data. In real life, the most commonly used data is decimal data, that is, every 10 to one. Let's take a look at the example: Binary: decimal 0 0 01 01 10 02 11 03 100 04 As you can see, in binary, there will be no numbers greater than 1, except that 0 is 1, but in decimal, there will be no 10, which is from 0 ~ 9. In our C #,
