In practice, the value of some variables is limited to a limited range. For example, there are only seven days in a week, 12 months in a year, and six courses per week in a class. It is obviously inappropriate to describe these values as integer,

I. Six operators in C language: & Bitwise AND | By bit or ^ Bitwise OR ~ Invert > Right shift  1. bitwise AND OPERATION Bitwise AND operator "&" are binary operators. Its function is the binary phase corresponding to the two numbers involved in the

Analysis on the Application of JavaScript bitwise operators Next, let's talk about the bit operations in js (also applicable to other languages) based on your own cognition. If there are any errors, please correct me. Most languages provide bitwise

Next, let's talk about the bit operations in js (also applicable to other languages) based on your own cognition. If there is an error, please note that most languages provide bitwise operators, bitwise operators are widely used in c, c ++, and

K&r Exercise 2-6,setbits (x,p,n,y), set the n bits from the p bit in x to the rightmost n-bit value in Y, and the rest of the x remain unchanged. #include unsigned setbits (unsigned x, int p, int n,unsigned y) { int mask; int pos=p+1-n;

I still don't like bitwise operations... Ah... I just saw a post about a netizen's bitwise operation reversing one byte on the Internet and posted it to learn to accumulate...Code: UnsignedCharReverse8 (unsignedCharC){C = (C &0x55) 1| (C &0xaa)>1

The bitwise inverse operator is reversed by each bit of the binary, such as the byte type, and the result of ~0 is 255.This function can do some reversal operation in maskThe following code, a contains three values of 2,4,8. Invert with bitwise

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
