c/c++面试题,很多经典的题，比如
/a和b交换面试题2.cpp
//如何将a、b的值交换，并且不使用任何中间变量？
//解析：
//简而言之，用异或语句比较容易，不用担心超界的问题。
//如果采用：
// a=a+b
// b=a-b
// a=a-b
//这样做的缺点就是如果a,b都是比较大的两个数，a=a+b时就会超界。
//而采用：
// a=a^b b=a^b a=a^b 无须担心超界的问题，这样就比较好。
//参与运算的两数个对应的二进制位相异或，当对应的二进制位相异时，结果为1。参与运算数仍以补码
//形式出现-c/c++ surface test, many of the classic title, such as/a and b exchanged face questions 2.cpp// how to a, b the value of the exchange, and do not use any intermediate variable?// Analysis:// In short, the use of different or expressions easier to not have to worry about the problem of super-sector.// If:// a = a+ b // b = ab // a = ab // of the shortcomings of doing so is that if a, b are two relatively large number, a = a+ b when super-sector.// Used:// a = a ^ b b = a ^ b a = a ^ b not have to worry about the problem of super-sector, so that is better.// Participate in a number of operations corresponding to the two binary bit different, or, when the corresponding binary bit different, the result is 1. Involved in computing the number of still meeting code// form
