∧: The function of the bitwise operator XOR "C"

Transferred from: http://blog.sina.com.cn/s/blog_74a459380101d6xl.htmlThe XOR operator, ∧, is also called. The rule is that if the two binary numbers of the operation are the same, the result is 0 (false); The XOR is 1 (true). That is 0∧0=0,0∧1=1,1∧1=0. such as:   071∧052, the result is 023 (octal number). "XOR" means to determine whether the two corresponding bit values are "XOR", for "XOR" (the value is different) to take the true (1), otherwise (0)
