对于指向同一对象或函数的两个指针a和b,在哪种情况下C标准保证a == b？当a和b指向同一个对象时,是否有任何平台可以保持！= b？
解决方法
根据C标准(6.5.9平等操作符来自N1548委员会草案 – 2010年12月2日ISO / IEC 9899：201x)
6 Two pointers compare equal if and only if both are null pointers,
both are pointers to the same object (including a pointer to an object
and a subobject at its beginning) or function,both are pointers to one past the last element of the same array object,or one is a pointer to one past the end of one array object and the other is a pointer to the start of a different array object that happens to immediately follow the first array object in the address space.109)
