C语言篇——使用运算符将16进制数据反转

        比如：将一个16进制0xFD，即11111101，反向，输出10111111，即0xBF。

#include <stdio.h>unsigned char reverseBits(unsigned char num) {unsigned char reverse_num = 0;int i;for (i = 0; i < 8; i++) {if ((num & (1 << i)))reverse_num |= 1 << ((8 - 1) - i);   }return reverse_num;
}int main() {unsigned char original = 0xFD; // 11111101unsigned char reversed = reverseBits(original); // 反转后的结果printf("Original: 0x%02X\n", original);printf("Reversed: 0x%02X\n", reversed); // 反转后的值return 0;
}
