>> Shift right Bitwise AND Operator & The output of bitwise AND is 1 if the corresponding bits of two operands is 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0. In C Programming, the bitwise AND operator is denoted by &. Let us suppose the...
shift_amount:指定变量需要右移的位数。 示例: #include <stdio.h>int main() {unsigned int num = 20; // 20的二进制表示为00010100int shift = 2;unsigned int result = num >> shift; // 右移2位printf("Original number: %u\n", num);printf("Shifted number: %u\n", result); // 输出应为...

XOR (^) operator NOT (~) operator Left Shift (<<) operator Right Shift (>>) operator Using Bit Masks AND (&) Operator: Performs a bitwise AND operation. Each bit is compared, and the result is 1 only if both corresponding bits are 1. When to Use: When you need to check if certa...
right shift operator>> shifts the binary bit of theequivalent to dividing by the n power of 2, which is more efficient Demo1 d << 2; // error, 左操作数必须是整型 int x = 10 >> 1; // ok,"右移等效除以2的n次方",输出5

voidbit_ctrl_1 (char*pflag,intbit) { (*pflag)=(*pflag)|(1<<bit); } 回想基礎知識所談的,假設我們要將一數的第2個bit設為1,我們會 | MASK,也就是 | (0000_0100),其中(0000_0100)就是(1 << bit),在此處bit為2,所以透過 << 這個shift operator,我們就能將MASK寫成活的。
