Demo2:bit operation method: XOR (two identical values XOR result is 0, any number and 0 XOR is still itself) #define SWAP(a, b) \ { \ a = a ^ b; \ b = a ^ b; \ a = a ^ b; \ } Anatomy of bitwise operators The C language was originally designed to develop the UNIX ...
printf("a=%d/nb=%d/nc=%d/n",a,b,c); } 2. 按位或运算 按位或运算符“|”是双目运算符。其功能是参与运算的两数各对应的二进位相或。只要对应的二个二进位有一个为1时,结果位就为1。参与运算的两个数均以补码出现。 例如:9|5可写算式如下: 00001001|00000101 ...
