No matter left shift or right shift, the result's sign should always bethe same as its left operand. By default, const numbers in C/C++ is signed. -Wsign-compare { unsigned intj = 3; intk = 5; if (j == (1 << (j))); //warning: comparison between signed and unsigned integer ...
A bit shift moves each digit in a number's binary representation left or right. There are three main types of shifts: Left Shifts When shifting left, the most-significant bit is lost, and a 00 bit is inserted on the other end. The left shift operator is usually written as "<<"....
The bitwise shift operators are the right-shift operator (>>), which moves the bits of an integer or enumeration type expression to the right, and the left-shift operator (<<), which moves the bits to the left.1 Syntax shift-expression: ...
位操作，比如输出变量的二进制形式：include <stdio.h> void binprint(void* x, int n){ typedef unsigned char byte;byte* p = (byte*)x + n - 1;byte a;while(p != (byte*)x - 1) { a = 0x80;do { putchar(*p & a ? '1' : '0');if(a & 0x11)putchar('_');}w...

1 row in set (0.00 sec) MySQL Right Shift operator MySQL Right shift operator returns an unsigned 64 bit integer. The return value will be zero when the shift count is greater than or equal to the width of a 64 bit unsigned number. It shifts the BIGINT number to the right. ...
The <<= operator shifts the bits of result left by the number of bits specified in expression. The operator masks expression to avoid shifting result by too much. Otherwise, if the shift amount exceeded the number of bits in the data type of result, all the original bits would be shifted...
