Bitwise operator in C/C++ 歡迎來到二進位的世界。電腦資料都是以二進位儲存,想當然程式語言的變數也都是以二進位儲存。在C/C++當中有幾個位元運算子:<< SHIFT LEFT、>> SHIFT RIGHT、& AND、| OR、^ XOR、~ NOT,可以對變數進行位元運算。接下來要介紹位元運算的一些用途。 << SHIFT LEFT >> SHIFT RIGHT ...
This complement operation is also called 1’s complement. The left shift (<<)and right shift (>>) are binary infix operators used, as in val << n and val >>n. They shift the bits in the first operand (val) by several bit positions specified in the second operand (n). When a ...
The compiler swap the given numbers, first, it converts the given decimal number into binary equivalent then it performs a bitwise XOR operation to exchange the numbers from one memory location to another. Explore our latest online courses and learn new skills at your own pace. Enroll and beco...
35 = 00100011 (In Binary) Bitwise complement Operation of 35 ~ 00100011 ___ 11011100 = 220 (In decimal) Twist in Bitwise Complement Operator in C Programming The bitwise complement of 35 (~35) is -36 instead of 220, but why? For any integer n, bitwise complement of n will be -(n ...
As a result, the bitwise left-shift operation for 13 (and any other number) can be different depending on the number of bits they are represented by. Because in 32-bit representation, there are many more bits that can be shifted left when compared to 4-bit representation.Previous...
Logical Shift: a logical shift is very similar to the arithmetic shift in that when you shift the digits, zero’s are filled into the void. So they perform exactly the same operation, it just that the logical will set 0’s on either end of the digits instead of setting the sign bit ...
In C, the Bitwise OR | operator is used to perform a bitwise OR operation between two integer operands. The operation compares corresponding bits of both
an in-place OR operation an in-place OR operation via special method 示例代码: s1 = {"a", "b", "c"} s2 = {"d", "e", "f"} s_or = s1 | s2 # OR, | print("s1: " + str(s1)) # s1 is unchanged print("s_or: " + str(s_or)) s1 |= s2 # In-place OR, |= pr...

Bitwise XOR ^, takes 2 bit patterns and perform XOR operation with it. 0101 0110 --- XOR 0011 --- The Bitwise XOR will take pair of bits from each position, and if both the bits are different, the result on that position will be 1. If both bits are same, then the result on ...
