The shift operation of C language is one of the most frequent operations that programmers use every day, and the shift operation can save us a lot of time and the program can be written more beautifully. We say that the shift operation can be

1. Left shift operatorThe left shift operator 1) Its general format is as follows:Value NUM Specifies the number of bits to shift the value to move.Left-shift rule remembers only one point: Discard the highest bit, 0 the minimum bitIf the number of

On most machines, the division of integers is slow and requires more than 30 clock cycles, divided by the power of 2, and can be implemented with shift operations. Code on first #include "stdio.h"int main (){int x=-128;int Y=X/4;printf ("y=%d", y);}

Big integer algorithm [05] shift operation, integer 05 In the previous blog post, we talked about operations related to the entire number of digits. This time the content is still related to bit operations: shift operations. It should be noted that

Let's say move left, move left to shift all bits of a number to the left, and in C with the int i = 1;i = i In other words, 1 of the 2 binary is 000 ... 0001 (here 1 the number of front 0 is related to the number of int, 32-bit machine, GCC has 31 0)

Depending on the result of the operation, other arithmetic shifts and logical shifts have no effect other than the right shift of negative numbers.(It usually happens in negative numbers)Logical right Shift: When you shift to the right, because the

About the shift left operator in C language, the shift left Operator Referring to c and pointer, the result of left shifting in c language is the same regardless of arithmetic or logical left shifting. In addition, perform the same operation for the
