angular interview question

size of the entire struct should also be an integer multiple of the maximum alignment value of the struct body.Of course, if the single-byte alignment is the ideal memory footprint.This is the most basic problem, if the answer is wrong, it should be despised.I hope I can shame and then brave.Reference Links:Why do I need byte alignment?http://blog.csdn.net/zkf11387/article/details/7662450Explain the structure, class and other memory byte alignmenthttp://zhangyu.blog.51cto.com/197148/673792/32-b

); }} Output[Email protected] The above example uses a factory to create instances of different objects, in this way can reduce the coupling degree of code, the code is greatly expanded, the previous to create Apple objects need to create Apple objects through the new keyword, if we also want to create an orange object? It would be cumbersome to create an instance from the New keyword and transform it up to fruit.Now we have a factory directly, you just configure the information in

cause any problems, that is, there is no reason to prohibit such assignment. In fact, the compiler does allow this assignment, which is where unique_ptr is smarter.in summary, when the program attempts to assign a unique_ptr to another, if the source unique_ptr is a temporary rvalue, the compiler allows this, and if the source unique_ptr will exist for some time, the compiler will disallow this , such as:Unique_ptr#1留下悬挂的unique_ptr (PU1), which can cause harm. and # # does not leave the danglin

Title Requirements:An array is formed by moving several bits to the left of a descending sequence, such as {4,3,2,1,6,5} is formed by {6,5,4,3,2,1,} left two bits, in which a number is found.Topic Analysis:Method 1 finds each one, iterates through the array, and the time Complexity O (N).Method 22 points to find, time complexity O (LOGN).

Recently encountered a technical interview question, here to share. The title is to design a function f that makes F (f (n)) =-N Here n is a 32-bit integer. You cannot use imaginary or plural operations. If you can't design a function to make it work for all integers under 32 bits, design this function so that it can be applied to as many integers as possible. Design a function f, such that: f (f (n))
